Chapter 8 - Harry Potter and the Knight of Hidden Truths Chapter Eight: The Shape That Remembers

Matthew woke before dawn to the sound of rain brushing against the windows of Gryffindor Tower.

For several moments, he remained beneath the closed curtains of his four-poster bed and allowed the unfamiliar dormitory to identify itself through sound. Wind moved around the outer tower in long, low breaths. Water whispered over the glass. Old timbers creaked somewhere above him as the castle settled beneath the changing weather. From the bed opposite came the soft rustling of Aidan Rookwood turning beneath his blankets, while Cormac McLaggen's snoring rose and fell with the determined rhythm of someone attempting to defeat silence through persistence.

No footsteps approached his bed.

No wand moved beyond the curtains.

Nothing inside the dormitory felt immediately dangerous.

Only then did Matthew turn his attention inward.

He began with his breathing, listening to the way each breath entered his chest and measuring the pull it created beneath his ribs. The cut crossing the edge of the web-like scar on his cheek had closed during the night. It remained tender, and a faint line of pressure travelled toward his right eye whenever his face tightened, but the pain was shallow rather than rooted. His shoulder was worse. The deeper ache left by Malcolm Avery's hold had settled beneath his collarbone and travelled into the branching curse pathway near his ribs.

Matthew lifted his right hand slowly. The third and fourth fingers answered a fraction later than the others, though both closed when he asked them to. He rotated his wrist, tested the elbow, and stopped before the movement pulled sharply through the shoulder.

Pain was information.

It was not always an order.

He placed two fingers against the diagnostic seam sewn inside his sleeping tunic. The enchanted thread warmed beneath his touch, responding first to identity and then to purpose. Three small marks appeared through the charcoal cloth.

The first indicated lingering inflammation.

The second showed that the golden survival current remained stable.

The third confirmed that no active dark residue had spread beyond the curse pathways established years earlier.

Matthew read the signs twice. His body was not telling him to remain in bed. It was not inviting him to behave as though the previous day had left no consequences either.

He pushed the curtains aside and sat carefully. The movement tightened the scar near his ribs, but the sensation remained a controlled pull rather than becoming sharp. He placed both feet upon the cool stone floor, waited until the weakened right leg accepted his weight, and stood.

Across the dormitory, Aidan's curtains opened by three inches.

One bright eye appeared through the gap.

Matthew looked directly at it.

The curtains closed.

"You are awake," Matthew said quietly.

Aidan's voice emerged from behind the fabric. "I am not."

"You opened the curtain."

"The curtain may have moved by itself."

"It is not enchanted."

"This is Hogwarts," Aidan replied after a thoughtful pause. "That feels like an unsafe assumption."

Matthew opened his expandable trunk and removed the lighter training layer of his ward-cloth. "You may come to the courtyard if you are dressed within five minutes."

Aidan's curtains flew open.

He was sitting upright with one sock already on his left foot and the other apparently missing somewhere beneath the blankets.

"Are we practising throws?"

"No."

"Blocks?"

"No."

"Anything impressive?"

"Standing correctly would be impressive at your current level."

Aidan looked wounded. "I stand every day."

"You occupy a vertical position every day. That is not always the same thing."

While Aidan searched beneath his blankets for the missing sock, Matthew changed into the training tunic. The soft inner cloth settled closely against his body without dragging over the scars. He left the heavier outer shoulder panels, impact channels, and divided battle-skirt layer inside the trunk. The recovery forms did not require protection from hostile force, and the extra weight might encourage his damaged shoulder to compensate in ways he would later have to unlearn.

His wand slid into the sheath inside his left bracer. The layered cedar-and-cherry wood warmed briefly against his forearm before becoming still.

Matthew had no intention of using it during training.

He also had no intention of walking through Hogwarts unarmed merely because the castle appeared quiet.

Aidan found his second sock inside his pillowcase.

He stared at it.

Matthew stared at him.

"I do not know how it got there," Aidan said.

"You put your socks beneath the pillow last night because Cormac claimed the dormitory mice steal clothing."

Aidan slowly remembered.

"Cormac said they only take left socks."

"You believed him enough to hide both."

"That was a strategic precaution."

"It was sleeping on your socks."

Aidan dressed while attempting to argue that the distinction mattered.

By the time they descended the spiral stairs into the common room, the fire had faded to red embers. Deep chairs and heavy curtains stood as dark shapes in the early light. A few abandoned books rested upon tables, and someone had left a chessboard near the hearth with one white knight continuing to pace irritably between two squares.

A folded paper bird waited upon the mantel.

One wing was longer than the other. Its beak pointed downward as though embarrassed by its own construction.

Matthew recognised Tonks's work.

He touched the bird, and the parchment unfolded across his palm.

Shadow-lion,

I have tea, toast, and permission to use the eastern courtyard. Professor Sprout says no one is to damage the statue, the floor, the school, or themselves.

I have questions. Some of them may be unreasonable.

Tonks

Aidan had leaned close enough to read the note while it lay openly across Matthew's hand.

Matthew folded it once the message ended.

"You may read correspondence which is being held where both of us can see it," he said as they crossed toward the portrait hole. "That does not apply to the linked book."

Aidan's expression sobered. "I understand."

"You attempted to read over my shoulder yesterday."

"I leaned."

"You leaned with your eyes."

Aidan's mouth opened. He appeared to search for a defence, failed to find one that would survive being spoken aloud, and closed it again.

"That sounds worse when described accurately."

"Most boundary crossings do."

The Fat Lady opened her portrait after Matthew gave the password, though she made no attempt to hide her displeasure at being disturbed.

"People your age should be asleep," she told them as they stepped through the opening. Her painted dressing gown was wrapped tightly around her, and small curlers remained in her hair. "Nothing sensible happens before breakfast."

"Training happens," Matthew replied.

"That proves my point."

The portrait swung closed behind them.

Hogwarts before dawn was quiet enough for its age to become visible. Torches burned low within iron brackets. Portraits slept behind painted curtains or rested with their heads against the edges of their frames. Suits of armour stood in recessed alcoves, motionless except for one visor which lowered hastily when Matthew looked toward it.

The staircases moved less frequently at that hour.

Matthew suspected this was because fewer students were available to inconvenience.

They descended through the sleeping castle, crossed a narrow passage behind the Charms corridor, and entered the eastern courtyard through a weathered stone arch. Its roof was supported by narrow columns marked with centuries of rain. Water had darkened the open half of the floor, and morning mist covered the grounds beyond the arches. The Forbidden Forest stood in the distance like a wall cut from the last darkness before sunrise.

Tonks waited beside the argumentative statue.

She wore loose grey training trousers beneath a faded Hufflepuff jumper. Her boots had close-fitting ankles, flexible soles, and no trailing laces. Her hair was dark blue rather than its usual pink, and a covered tray beside her held a teapot, four cups, and enough toast to occupy all of Aidan's immediate attention.

The statue held a carved stone apple in one hand and appeared to be watching the food.

Tonks pointed at it as Matthew approached. "I told him the toast is not for statues."

"Did he answer?"

"He threw a pebble at my cup."

"That means he understood."

"It means he is rude."

The statue's shoulder shifted.

A pebble left its hand.

Matthew turned his head just enough for the stone to pass beside his cheek. It struck the arch behind him and broke into two smaller pieces.

Tonks stared.

"You knew that was coming."

"His shoulder moved."

"He is made of stone."

"Movement remains movement."

Aidan reached toward the toast.

Tonks caught his wrist without looking.

"Training first."

"You placed food directly in front of us."

"I brought a reward."

"That is manipulative."

Tonks released him and grinned. "I am nearly an adult. We are permitted several advanced methods."

Matthew unfolded his training mat upon the driest section of the floor. When he straightened, Tonks's attention moved briefly to the way his right shoulder remained slightly lower than the left.

She did not ask whether he was fine.

Instead, she indicated the scar line disappearing beneath his collar. "How does the pathway feel?"

"Warm, moderately tight, and stable under ordinary breathing. The diagnostic seam shows inflammation without spread."

"Recovery work?"

"Yes."

Tonks nodded once.

No permission followed.

No order followed either.

That improved the morning immediately.

Matthew stepped onto the mat and brought his feet beneath his hips. He allowed his toes to face naturally forward, softened his knees, and let his spine rise without becoming stiff. His arms rested loose at his sides, the hands open and unprepared for either attack or defence.

Tonks moved to the opposite edge of the mat.

"Before we begin," Matthew said, "I can show you the postures, breathing, balance transfers, and recovery movements Mrs Tanaka taught me. I have more experience than you, but I am still her student. I will not pretend that experience gives me authority I have not earned."

Tonks raised both eyebrows. "You do not need three portraits, a magical book, Hermione, Vivian, and your martial-arts teacher to approve me standing?"

"No. You are capable of deciding whether you wish to stand and breathe."

"I prepared several arguments."

"Keep them. You may need them during a future disagreement."

Aidan sat cross-legged beside the tray. "I already know how to stand."

Matthew looked at him.

Aidan corrected himself. "I know how to remain off the floor."

"That is a more accurate beginning."

Matthew raised one hand and pointed to his own feet.

"This is the neutral posture. Mrs Tanaka calls it wuji, although she usually translates it as the place before movement. The feet remain beneath the hips. The knees are not locked. The pelvis is neither pushed forward nor pulled back. Your weight rests through the whole foot rather than collecting in the heels."

Tonks looked down at her stance and shifted experimentally.

"Why begin here?"

"Because most people hide unnecessary effort inside the way they stand. They grip their toes, lock their knees, raise one shoulder, or lean toward whatever they expect to happen. If you begin from a lie, every movement after it has to compensate."

Tonks's expression grew thoughtful.

She moved her weight forward.

Matthew shook his head. "You are leaning toward me."

"I am ready."

"You are anticipating."

"Is that bad?"

"It means I already know which direction you will struggle to move away from."

He lifted his left palm and pressed lightly toward her shoulder without making contact.

Tonks shifted backward automatically. Because her weight had already travelled forward, her upper body retreated before her hips did, and she had to move one foot to catch herself.

Matthew waited.

She stared at him.

"I understand."

"Good. Return to the beginning."

Tonks placed her feet again, this time allowing the weight to settle evenly.

Matthew moved to the next stance.

He widened his feet, though not far enough to place strain through the damaged hip. His knees tracked over his toes, and his centre lowered by only a few inches.

"This is a shallow horse stance. It teaches the legs to support the centre without the knees collapsing inward or the shoulders becoming involved."

Aidan stood from beside the tea and spread his feet dramatically.

Matthew looked at him.

Aidan lowered farther.

His thighs began trembling within five seconds.

"You are too wide," Matthew said.

"I thought lower was stronger."

"Lower is lower. Strength depends upon whether the structure can carry what you ask of it."

Aidan tried to rise without allowing anyone to see that he needed to. His knees wobbled.

Tonks covered a smile.

Matthew stepped out of the stance and brought his feet nearer together. He turned the toes slightly inward and allowed the knees to draw gently toward the centre without touching.

"This is the inward-rooted stance Mrs Tanaka uses for Wing Chun. She calls it the character-two stance because of the old written shape associated with the feet. The hips remain neutral. The knees protect the centre line. It is not meant to make you immovable. It gives you a stable position from which either leg can move."

Tonks copied him.

She drew her knees too tightly and immediately became uncomfortable.

"You are clamping," Matthew told her.

"You said the knees come inward."

"They come inward enough to protect the line, not enough to quarrel with each other."

Aidan gave an approving hum.

Tonks pointed toward him. "You are still recovering from the horse stance."

Aidan sat down.

Matthew demonstrated a slow forward weight transfer. His left foot stepped along a narrow line. The heel touched first, then the rest of the foot settled as his centre travelled forward. The right leg remained rooted without locking.

"This is a bow stance, although Mrs Tanaka keeps mine shorter because of the right leg. Most of the weight moves forward, but not all of it. If every part of you commits to one direction, you have nothing left for change."

Tonks stepped.

Her front knee travelled beyond her toes.

Matthew lifted two fingers.

"Stop. Bring the hip back until the knee sits above the foot."

She corrected it.

"Why?"

"Because the knee is a hinge, not a foundation. When your centre outruns the foot, the joint carries force it cannot redirect."

Tonks adjusted again. The line from hip through knee to heel became cleaner.

Matthew nodded.

"Better."

The ends of her dark blue hair became faintly pink.

He moved into an empty stance next, placing most of his weight through the rear leg while allowing the front toes to rest lightly against the floor.

"This teaches the difference between contact and commitment. The front foot touches the ground, but it is free to move. Mrs Tanaka sometimes calls it a cat stance."

Tonks looked delighted. "A cat stance?"

"It is not for pretending to have paws."

"That was not what I was thinking."

"It was exactly what you were thinking."

Tonks's boots narrowed slightly as her feet instinctively changed shape.

Matthew pointed downward.

"You are already using Metamorph magic."

She stared at her feet.

The front boot had shortened around the toes, reducing the amount of sole resting against the floor.

"I did not mean to do that."

"Your magic changed the body to match the idea of lightness."

"Is that cheating?"

"No. It is part of your body. It also means you need to understand when your magic is compensating, because otherwise you may mistake the result for ordinary balance."

Tonks's expression became serious.

No one had apparently framed her ability that way before.

She resumed the stance without changing the foot.

Matthew moved through each posture again, joining them into a slow recovery sequence. Neutral stillness became a shallow horse stance. The weight shifted left. His hands rose as though supporting a large sphere of air between them. He turned from the waist, allowing the right shoulder to follow only as far as the scar pathway permitted. From there, he stepped into a short bow stance, circled one palm inward, and returned into an empty stance without allowing the weakened right knee to collapse.

The golden current awakened beneath his scars.

Warmth travelled from the centre of his chest toward the right hip. It passed along the old curse pathways beneath the skin and moved upward across his side. Near the injured ribs, the current hesitated.

Matthew did not force it through.

He softened his shoulder, lengthened the exhalation, and allowed the magic to take a broader route across his back. The inner ward-cloth warmed along the alternative channel, reinforcing the path without dragging the current into it.

Gold became faintly visible beneath the scars across his right hand.

Tonks watched without speaking until the movement ended.

"Is it always visible?"

"No. It is easier to see when it travels near the surface or meets resistance."

"Is it healing you?"

"It supports the body while the body attempts to heal. Support and healing are not always the same."

Tonks folded her arms loosely. "What is the difference?"

"Healing changes the damage. Support helps the structure continue despite it. Sometimes support creates conditions in which healing becomes possible. Sometimes it only keeps the damage from becoming worse."

Tonks looked at the light fading beneath his skin.

"So the magic that kept you alive might also have kept you functioning without actually curing you."

"Yes."

"That sounds like something a Defence professor would write on a board."

Matthew lowered his hands. "I have not met Professor Wardwell properly."

Tonks's gaze shifted toward the mist beyond the arches.

"You will."

The words carried a slight change in weight.

Matthew noticed.

"You know her."

"I know of her."

"That is not the same answer."

"No," Tonks agreed. She met his eyes again. "I will share what belongs to me when I understand which parts those are."

Matthew accepted the boundary without attempting to force it.

"Watch the sequence again."

He repeated it more slowly, naming each transition and showing where the movement originated. Tonks copied him. During the first turn, her hands reached the final position before her hips had completed the motion, leaving her upper body suspended ahead of her centre.

Her left foot widened inside the boot as her Metamorphmagus magic attempted to correct the imbalance.

Matthew stopped.

"Your foot changed."

Tonks stared downward.

The front of her boot had widened around the toes.

"I do that?"

"Your magic compensates before you fall."

"Then why do I fall so often?"

"You commit to the mistake faster than the magic can correct it."

Aidan coughed into his sleeve.

Tonks glared at him.

Matthew continued before the lesson became entirely humour.

"Move more slowly. Do not perform the final shape. Build the path which creates it."

Tonks returned to the neutral posture. This time she began the turn from the floor, allowing pressure to move through the leg and hip before the shoulder followed. Her hands arrived with the rest of her rather than reaching ahead.

The movement remained imperfect, but her centre stayed balanced.

Matthew nodded. "Better."

The ends of Tonks's blue hair became bright pink.

The statue's shoulder shifted again.

A pebble flew toward her.

Without leaving the empty stance, Tonks transferred her weight into the rear leg and allowed the stone to pass beside her chest.

She stared at the statue.

Then she looked at Matthew.

"I did not fall."

"You did not."

"My foot did not change either."

"It did not need to."

Aidan raised one hand. "May I attempt the sequence?"

"You may attempt the neutral posture and the shallow horse stance. You are not moving into the turn until I check your feet."

Aidan stepped onto the edge of the mat and immediately slid upon the wet stone.

Tonks caught the back of his robe.

Matthew looked at him.

"I had not checked your feet."

"I was preparing them for inspection."

"You were falling before the inspection began."

"That seems like useful evidence."

Matthew corrected Aidan's posture. Aidan pushed his chest forward because he believed standing tall required displaying it. Matthew pressed two fingers lightly against the centre of his back.

"You are not a ship's figurehead."

"I was aligning my spine."

"You were announcing your ribs."

Tonks laughed so suddenly that she lost her own stance.

The statue threw a pebble at her.

She caught it badly, fumbled, and nearly dropped it into the teapot.

Aidan looked pleased to have company in failure.

They continued until the first breakfast bell rang somewhere inside the castle. Matthew completed only the recovery sequence, though the urge to continue into the sharper Wing Chun forms remained. The previous day's confrontation lived close beneath his skin. His body wanted to repeat the motions which had protected it, testing each one until the memory became control rather than surprise.

He recognised the desire.

He did not mistake it for need.

His body had already answered the important questions.

The golden current moved.

The shoulder remained stable.

The rib pathway had not reopened.

Additional strain would prove nothing.

Matthew stepped off the mat.

Tonks poured tea into four cups. Aidan took two pieces of toast with the speed of someone afraid the permission might be withdrawn.

"You look different after training," Tonks said.

Matthew held the warm cup between both hands. "How?"

"Before you begin, it sometimes looks as though you are carrying your body because no one else can. When you finish, you look as though you live inside it."

The words entered somewhere Matthew had not prepared to defend.

For most of his life, his body had been something he negotiated with. It hurt, resisted, remembered, weakened, warned, and occasionally failed. He had strengthened it because leaving it damaged and ignored would have given the curse too much ownership.

Living inside it sounded different.

Tonks did not demand an answer.

She drank her tea and looked toward the brightening grounds, allowing the silence to remain his.

That improved her more than any question could have done.

Aidan finished his second piece of toast and looked into the nearly empty basket.

"Is this all the breakfast?"

Tonks stared at him.

"This was training food."

"I trained."

"You stood for thirty seconds and nearly fell twice."

"That consumed energy."

Matthew folded the mat. "We can stop at the Great Hall before returning to the tower."

Aidan looked relieved.

Tonks lifted the tray. "Good. I made the mistake of believing four pieces of toast would be enough for three growing children and one nearly adult Hufflepuff."

"You ate one of them," Aidan pointed out.

"I carried the teapot."

"That is not training."

Tonks's hair began turning red at the ends.

Matthew stepped between the argument and the remaining toast.

"We will obtain more food."

They left the courtyard together.

The castle was waking around them now. Portrait curtains opened. Suits of armour stretched with metallic groans. Students began appearing along the staircases in varying states of dress and consciousness. Somewhere above, a prefect shouted that a staircase was not a slide and received laughter in reply.

The Great Hall was only partly full when they arrived. The enchanted ceiling showed a grey morning sky streaked by thin clouds. Early students occupied scattered places along the four House tables, while plates of eggs, sausages, toast, porridge, mushrooms, and fruit replenished themselves whenever a serving dish became low.

Tonks moved toward the Hufflepuff table but stopped when Aidan looked at the distance between them and the food.

"I will see you later," she said. "Try not to correct any professors before the first bell."

"That depends upon whether they say anything incorrect," Matthew replied.

Tonks pointed at him. "That answer is exactly why I added the warning."

She crossed toward Hufflepuff.

Matthew and Aidan sat near the end of the Gryffindor table. Elara and Katie arrived several minutes later, both already dressed for the day. Elara carried her timetable folded into an exact square. Katie's hair remained damp from an early shower, and she had tucked a piece of toast between her teeth while trying to fasten her bag.

"You trained again," Elara said after examining Matthew's posture.

"Yes."

"How is the shoulder?"

"Inflamed but stable."

Katie sat opposite him and freed the toast from her mouth. "Tonks told us you were teaching her not to fall."

"I am showing her how to recognise the point before the fall becomes unavoidable."

Aidan filled his plate.

"She made me stand."

Elara looked at him. "You already stand."

"That is what I said."

Matthew poured tea.

"He occupies a vertical position."

Katie laughed into her cup.

Matthew ate eggs, mushrooms, two pieces of toast, and enough porridge to satisfy the part of Vivian's voice which remained inside his head during breakfast. There was still no curry.

The absence no longer surprised him.

It remained disappointing.

After eating, Matthew and Aidan returned to Gryffindor Tower for showers and school robes. The boys' washroom stood beyond the dormitory beneath a vaulted stone ceiling. Copper pipes ran visibly along one wall before disappearing into the castle. Steam had already clouded the mirrors, and several other first-years were arguing about which taps controlled hot water.

Matthew waited until a screened stall became free.

Privacy mattered for reasons beyond modesty. The branching curse scars crossed most of his right side, and he had no desire to answer questions while washing. He removed the training tunic carefully, folding it so that the inner diagnostic seam did not touch the wet floor.

Hot water loosened the muscles around his shoulder and carried the last chill of the courtyard from his skin. It did not remove the deeper pain. Heat sometimes made the scar pathways more sensitive, but this morning the response remained mild. Matthew placed one hand against the wall while testing the reach of the injured arm, stopping before discomfort became strain.

Beyond the screen, Aidan was trying to discover whether the shower water could be made to change temperature through polite requests.

"It responds to the taps," Matthew told him.

"I was testing for personality."

"The pipes do not require encouragement."

"This is Hogwarts. That feels like another unsafe assumption."

Matthew dried, checked the scar line once more, and dressed in the full school version of his ward-cloth. The charcoal tunic crossed diagonally over the left side of his chest. Overlapping shoulder panels protected the right without pressing against it. Four divided lower panels moved beneath his ordinary black school robe, and the silver runic seams remained nearly invisible until active.

His black-framed glasses settled over the web-like scar near his right eye.

The familiar shape helped.

By the time they left Gryffindor Tower again, Elara and Katie were waiting near the portrait hole. The four of them descended together toward the first-floor Transfiguration classroom.

They encountered Cassian Flint near the central staircase.

He was not alone.

Dorian Selwyn leaned against the stone beside him, one wrist wrapped beneath his sleeve after the previous day's fight. Malcolm Avery stood on Cassian's other side, his broad shoulders filling part of the corridor. Two younger Slytherins lingered several steps behind them, attracted by the possibility of trouble but uncertain whether they wanted to be included in it.

Cassian's eyes moved first to Matthew's face and then to his right hand.

"Back on your feet," he said.

Matthew continued walking until the distance between them remained safe but conversation no longer required raised voices.

"Yes."

Dorian's mouth tightened. "You should have gone to the hospital wing."

"That is an unexpected concern."

"It was not concern." Dorian shifted his injured wrist beneath the sleeve. "Some injuries take longer to finish their work."

Aidan's posture changed beside Matthew. His shoulders rose, and his right hand began moving toward his wand.

Matthew spoke before the motion completed.

"Do not."

Aidan stopped.

Matthew kept his attention on Dorian.

"Your wrist appears functional," he said. "That is fortunate. I released it before causing permanent damage."

Malcolm's face darkened.

"You think that makes you merciful?"

"No. It makes the response proportionate."

Cassian glanced toward the classroom doors farther down the corridor, where Ravenclaw students had begun arriving.

"You speak as though rules protect you."

"I speak as though your previous choices created evidence."

Dorian stepped away from the wall.

Elara moved quietly to Matthew's right side. Katie came to his left, not reaching for a wand but making it clear that he was no longer standing alone.

Matthew noticed.

So did the Slytherins.

Dorian's gaze passed over the four Gryffindors before returning to Matthew.

"The Knight family was meant to end."

"That is an opinion you have already expressed."

"It is a fact the Ministry recognised."

"The Ministry also failed to recognise that I was magical while I was alive and living in Britain. Its paperwork does not possess the authority to kill me retroactively."

One of the younger Slytherins made a choking sound which might have been a suppressed laugh.

Cassian turned sharply toward him.

The boy looked at the floor.

Malcolm pushed one shoulder away from the wall, but Dorian lifted his uninjured hand.

"Not here."

The words were meant for Malcolm, but his eyes remained on Matthew.

Matthew stored the distinction.

They were not choosing peace.

They were choosing a location with too many witnesses.

Professor McGonagall's classroom door opened.

Her voice travelled into the corridor.

"Students who intend to attend Transfiguration will enter. Students who prefer to obstruct the passage will explain the decision to their Heads of House."

Cassian's expression tightened.

Dorian and Malcolm moved aside.

Matthew did not look back as he entered.

His friends stayed with him.

That mattered more than any reply he could have made.

Transfiguration was shared with Ravenclaw.

The classroom occupied the first floor beside a high corridor overlooking one of Hogwarts's inner courtyards. Rainwater glistened upon slate roofs below. Narrow streams poured from the mouths of gargoyles and disappeared into drains between the flagstones. Inside, rows of desks faced a raised platform and a broad blackboard. Each place held a matchbox, a square of white cloth, and a copy of A Beginner's Guide to Transfiguration.

No professor stood at the front.

A silver tabby cat sat upon the teaching desk.

Its tail curled neatly around its paws. Dark markings surrounded its eyes in square shapes closely resembling the frames of Professor McGonagall's spectacles. The cat watched each student enter with an attention too deliberate for an ordinary animal waiting to be fed.

It observed who arrived late.

It watched which hands reached toward the matchboxes before permission.

It looked longest at Aidan, who had brought another piece of toast from the Great Hall and was attempting to conceal it behind his back.

Matthew stopped near the first row.

Before he could speak, a Ravenclaw girl with two dark braids and a blue ribbon around one wrist hurried toward the desk.

"Oh, you are beautiful."

The tabby's ears moved backward.

The girl did not notice.

She reached beneath the cat's front legs and lifted it from the desk.

Every muscle in the animal became still.

Cho Chang, standing several desks away, drew in a breath.

"Phoebe," she warned.

The girl named Phoebe held the cat against her chest and smiled into its face.

"You have little glasses."

The cat stared at her with the concentrated displeasure of a senior professor assessing a particularly avoidable mistake.

Phoebe leaned forward.

"I am going to kiss your—"

The cat raised one paw and struck her smartly on the forehead.

No claws appeared.

The sound was still loud enough to silence the room.

Phoebe froze.

The tabby pressed both rear paws against her chest, dropped neatly from her arms, and returned to the desk. It sat, wrapped its tail around its feet, and gave the girl a look so stern that several students straightened instinctively.

Phoebe touched the place where the paw had landed.

"I think the cat told me no."

"Yes," Cho said. "Very clearly."

Aidan's mouth was trembling with the effort not to laugh.

Matthew's was not much better.

He approached the desk with his expression arranged into what he intended to be respectful calm. The attempt was undermined by the smile he was hiding badly at one corner of his mouth.

"Good morning, Professor," he said. "That is a wonderful Animagus transformation."

The cat's whiskers twitched.

Its eyes narrowed at the smile.

Matthew inclined his head and went to his seat before he lost the argument with his own amusement.

Aidan followed him.

"You knew."

"The spectacle markings were relevant."

"You also watched her hit Phoebe."

"That confirmed intelligence and authority."

"It confirmed she dislikes kissing."

"That was already clear before contact."

Julian Quill entered with the remaining Ravenclaws and followed Matthew's gaze toward the cat.

"You recognised Professor McGonagall."

"Yes."

Julian looked at Phoebe, who had taken a seat while continuing to rub her forehead.

"How?"

"The markings resemble her spectacles. She is sitting upon the teaching desk, observing punctuality and equipment handling, and she issued a nonverbal boundary with perfect control."

Phoebe looked embarrassed.

"I thought she was a cat."

"She is a cat," Matthew said. "She is also the professor."

The final student entered.

The door closed.

The tabby leapt from the desk.

Silver fur drew inward before its paws touched the floor. The body lengthened. Green robes unfolded from the transformation, and Professor McGonagall landed upright with her spectacles already resting on her nose.

Phoebe became very pale.

McGonagall adjusted one sleeve.

"Miss Fairbourne."

"Yes, Professor?"

"An unfamiliar animal's tolerance of proximity is not permission to lift it."

"No, Professor."

"An animal being attractive is not consent to kiss it."

"No, Professor."

"And a professor's Animagus form does not become school property merely because she has not yet introduced herself."

Phoebe swallowed.

"No, Professor."

McGonagall regarded her for another moment.

"Five points from Ravenclaw for ignoring a clearly communicated warning. One point returned for identifying the boundary after it was expressed more forcefully."

Phoebe sat very still.

McGonagall's eyes moved toward Matthew.

"Mr Knight."

"Yes, Professor?"

"You recognised me."

"The markings around your eyes resembled your spectacles, and your behaviour suggested a teacher assessing the room."

"You might have addressed an ordinary cat."

"An ordinary cat would probably have ignored the title. An unannounced professor might reasonably expect observation."

Her gaze sharpened slightly.

"You also appeared entertained by Miss Fairbourne's error."

Matthew's hidden smile finally escaped.

"Only after you had established that she was unharmed."

The corner of McGonagall's mouth moved by less than a smile.

"Five points to Gryffindor for observation. None for the poorly concealed amusement."

"That seems fair."

Aidan leaned toward Matthew.

"You received points for speaking politely to a cat after watching it strike a Ravenclaw."

McGonagall heard him.

"Mr Rookwood, Mr Knight received points for examining what the rest of the class accepted without sufficient thought."

Aidan sat straighter.

Phoebe raised her hand timidly.

"Yes, Miss Fairbourne?"

"Was the paw part of Transfiguration?"

"No. That was discipline."

Several students laughed.

McGonagall allowed the laughter to last three seconds.

Then she turned toward her desk and raised her wand.

The polished wood shuddered.

Its carved legs bent and thickened into living limbs. Drawers folded inward as a broad pink body emerged from the transformation. The desktop softened into a rounded back, while an old ink stain near one corner became a dark patch above the animal's shoulder. The brass handle of the centre drawer narrowed into a small curl of tail.

A pig landed upon four hooves.

It snorted.

The class fell silent.

The animal took three steps toward the first row, its nose moving as it investigated the air. It approached Aidan's bag, smelled the concealed toast inside it, and began pushing insistently against the flap.

Aidan looked at McGonagall.

"Professor?"

"You brought food into my classroom."

"I did not know your desk would become interested in it."

"The desk was not interested."

The pig pushed harder.

Aidan held the bag closed.

"The pig appears very interested."

McGonagall allowed the animal one final snort before reversing the spell.

The pig's body straightened and broadened. Pink flesh hardened into polished wood. Hooves became carved legs, the tail returned to brass, and the ink stain reappeared in precisely the same place.

Aidan's toast remained inside his bag.

"Transfiguration," McGonagall said as she walked around the restored desk, "changes form, substance, or nature. It is not an illusion, disguise, or charm laid over the surface. During the transformation, the desk possessed the material characteristics and sufficient behavioural qualities of a pig."

Matthew raised his hand.

McGonagall looked unsurprised.

"Yes, Mr Knight?"

"Did it possess an independent mind?"

Several students turned.

"It possessed sufficient animal consciousness to behave according to the transformed state," McGonagall answered. "It did not become an unrelated animal with an independent childhood, ancestry, or history."

"What would have happened if it had been injured?"

"Damage inflicted upon a transformed object may carry back into the original state. The precise result depends upon the injury, the spell, the caster, and the stability of the transformation."

"Then reversibility does not remove responsibility."

"No." Her answer carried more weight than its size. "It does not."

Matthew recorded that.

McGonagall waited until his quill stopped.

"Transfiguration is not permission to treat identity as disposable. Talented students often understand that lesson later than they should."

Her gaze remained upon Matthew long enough to make the warning personal without becoming an accusation.

Aidan raised his hand.

McGonagall looked wary.

"Yes, Mr Rookwood?"

"If the desk was completely a pig, could someone have eaten it?"

The room became silent.

Matthew closed his eyes briefly.

McGonagall stared at Aidan over the top of her spectacles.

"No one will eat my desk."

"I was asking theoretically."

"You were carrying toast illegally."

"Both things can be true."

Elara covered her mouth.

McGonagall's expression did not change, but a dangerous quiet entered her voice.

"Your question is poorly phrased, Mr Rookwood, but it leads us toward a law you will need to understand before anyone decides Transfiguration is a solution to hunger, poverty, or an empty breakfast plate."

She turned toward the blackboard.

Five words appeared in clean white script.

TARGET

DESTINATION

CORRESPONDENCE

STABILITY

REVERSIBILITY

Above them, she wrote:

GAMP'S LAW OF ELEMENTAL TRANSFIGURATION

A murmur moved through the room.

McGonagall placed her wand upon the ledge beneath the board and faced the class.

"Gamp's Law is not one charming sentence which students may memorise and then use to win arguments. It is a body of principles describing what Transfiguration may alter, what it cannot create, and where apparent success conceals failure."

She touched the word TARGET.

"Transfiguration begins with something. A match, a desk, a stone, a cup, a living creature, or even the caster's own body. Magic may rearrange substance, impose a new form, or temporarily alter qualities, but the original target matters. Mass, material, magical history, living structure, and existing enchantments all influence the result."

Her wand moved to DESTINATION.

"The intended form must be understood. A student who knows only that a needle is silver and pointed may create a silver-painted splinter. A student who understands steel, hardness, temperature, flexibility, eye, point, and purpose has a better destination."

At CORRESPONDENCE, McGonagall lifted a match from the front desk.

"Transfiguration is easier when source and destination share useful correspondences. A match and needle are both narrow, light, and straight. They differ in substance, function, temperature, flexibility, and construction. Correspondence provides a bridge. It does not remove the distance."

Julian raised his hand.

"Does that mean larger differences require more power?"

"Not merely more power," McGonagall replied. "More knowledge, finer control, stronger stability, and a clearer magical model. Brute force applied to a poorly understood transformation produces a larger mistake."

She pointed to STABILITY.

"A transformation which remains correct for half a second is not useful because it was briefly impressive. The transformed structure must hold without constant uncontrolled correction."

Finally, she touched REVERSIBILITY.

"A responsible caster retains the route back. This does not mean refusing the transformed state. It means that change without recovery may become destruction wearing academic robes."

Matthew copied the sentence.

McGonagall moved beneath the title of Gamp's Law.

"Elemental does not refer only to fire, water, earth, and air. In this context, it concerns fundamental substance and the properties which make a thing materially and magically what it is."

Cho raised her hand.

"Does Transfiguration create matter?"

"It may appear to," McGonagall answered, "but appearance is not always creation. In ordinary school transformations, existing matter is reorganised. Advanced conjuration may bring an object into presence through more complicated means, but it remains subject to source, magical cost, stability, and Gamp's limits."

Julian's quill moved quickly.

McGonagall continued.

"The best-known portion of Gamp's Law is the five Principal Exceptions. Food is the first. It cannot be created from nothing."

Aidan looked down at the toast hidden inside his bag as if reconsidering its value.

"You may summon food if you know where it is," McGonagall said. "You may enlarge or multiply existing food within sensible magical limits. You may transform food which already exists. What you cannot do is wave a wand at empty air and create genuine nourishment from no source."

Phoebe raised her hand, more cautiously this time.

"What happens if someone tries?"

"The spell may fail. It may create an imitation with no proper nourishment. It may produce an unstable substance which collapses. It may borrow matter from a source the caster did not intend. None of those outcomes should be mistaken for solving hunger."

Aidan raised his hand again.

McGonagall sighed almost invisibly.

"Yes?"

"Could you transform a desk into a pig, then the pig into bacon?"

"No."

"But—"

"No one is eating my desk, Mr Rookwood."

The laughter returned.

McGonagall allowed it to fade.

"More importantly, a living transfiguration is not a convenient path around Gamp's Law. The transformed pig does not become a legally, ethically, or magically acceptable food source simply because the surface problem appears solved. Living transformations possess animating patterns, magical continuity, and a route to reversal. You will not test where nutritional substance ends and furniture begins."

Aidan lowered his hand.

Matthew raised his.

"May I ask a related question?"

"You usually do."

"If a person transfigured ordinary matter to resemble food, the appearance and flavour might be reproduced, but the nourishment would remain limited by the source and Gamp's Law."

"Correct."

"Then a transformed result may satisfy the senses without fulfilling the essential purpose."

McGonagall's eyes sharpened.

"Yes. That principle extends well beyond meals."

Matthew thought of Dumbledore calling silence protection.

The form of safety could be reproduced while the purpose was absent.

He wrote:

An object may resemble the answer without performing the answer's essential work.

McGonagall noticed the sentence.

She did not ask what had inspired it.

A Ravenclaw boy near the windows raised his hand.

"What are the other four Principal Exceptions?"

McGonagall looked across the class.

"You will not receive a speculative list merely because the phrase contains the number five. The remaining exceptions involve distinctions in substance, life, identity, magical essence, and permanence which are beyond first-year practice. Some popular books simplify them badly. Some families teach private versions as if tradition were universal law."

Matthew's quill paused.

McGonagall continued.

"You will learn what is established when you possess enough theory to understand why the limitations exist. Until then, remember the part you can use safely: magic is not an unlimited substitute for source, knowledge, labour, consent, or consequence."

Elara lifted her hand.

"Could someone transfigure worthless metal into gold?"

"They might create the appearance of gold," McGonagall replied. "A skilled caster might temporarily reproduce many physical properties. Permanent valuable-metal transfiguration is considerably more difficult, easily detected by Gringotts and Ministry wards, and not a path to infinite wealth."

Aidan leaned toward Matthew. "The goblins thought of that."

"They think of most financial crimes before wizards do."

McGonagall's gaze moved toward them.

"Would either of you like to share?"

"No, Professor," they said together.

Cho asked, "Can water be conjured?"

"Yes. Water does not fall under the food exception in the same way, though conjuration, purity, quantity, and safety still matter. A spell producing water does not guarantee that the result is appropriate for drinking, potion-making, or medical use."

Matthew raised his hand again.

McGonagall looked at him.

"What about injured tissue?"

The room became quieter.

"If a scar were transfigured into healthy-looking skin, would the original damage be removed, hidden, or displaced?"

McGonagall's gaze moved briefly toward the web-like scar across his cheek.

"That depends upon the scar."

"If it contained curse residue?"

"Then ordinary Transfiguration would not cleanse it."

The answer came without hesitation.

"Human Transfiguration might alter appearance, texture, flexibility, or even some physical structure. It would not automatically identify and remove dark magic embedded inside nerves or magical pathways. At best, it could hide the evidence. At worst, it might change the tissue while preserving the contaminant in a more dangerous form."

Matthew's right hand became still over the parchment.

"So it could make a wound look healed without healing it."

"Yes."

The words carried no softness.

That made them easier to trust.

McGonagall looked at the entire class.

"Another lesson worth remembering: changing what can be seen does not necessarily change what is true."

Matthew wrote that beneath the first sentence.

Gamp's Law was not merely a rule against creating food.

It was a warning against confusing resemblance with reality.

McGonagall returned to the practical work.

The exercise was match-to-needle transformation.

She placed one match upon the white cloth at the front.

"The target must become narrower, metallic, hard, cold, pointed, and hollowed at one end to create an eye. Changing colour is not enough. Changing shape is not enough. The match must materially become a needle."

She demonstrated the wand movement. It was shorter than Matthew expected, a precise turn and directed tap rather than a large gesture. The match flashed silver and fell against the cloth with a clear metallic sound.

"Your incantation will assist focus, though the movement and intended correspondence matter more than volume."

Students began.

Aidan's first match stretched into a long wooden splinter and developed points at both ends.

He held it up carefully.

"I have created an aggressively impractical needle."

Elara looked over from the desk ahead. "You have created something capable of injuring two fingers at once."

Katie's first attempt turned silver at one end and remained wood at the other. Cho produced a narrow metallic shaft without an eye. Julian's match became hard and cold but retained the smell and grain of cedar.

Phoebe Fairbourne's first attempt grew four small legs.

She stared at it.

McGonagall appeared beside her.

"What was your intended destination?"

"A needle."

"Why does it have legs?"

Phoebe looked toward the teaching desk.

"I may still have been thinking about the pig."

"Then stop allowing earlier spectacles to interfere with current instructions."

The four-legged match attempted to walk away.

McGonagall returned it to ordinary wood with one tap.

Matthew placed his own match upon the cloth.

He examined it before casting.

The wood was light and dry. Grain ran lengthwise. One end carried a darkened chemical head. The destination required steel, point, eye, flexibility, coldness, and a complete change of purpose.

He understood what the object needed to become.

That was not the difficulty.

Matthew lifted his wand.

He traced the movement.

The match narrowed. A point formed at one end. A small eye opened at the other. Silver spread across the surface.

It looked almost perfect.

Matthew touched it.

Warmth remained within the object.

The wood grain showed beneath the metallic sheen.

Professor McGonagall appeared beside him.

"You changed appearance, shape, and surface behaviour," she said as she lifted the false needle. "The core remains wood."

"I preserved too much of the source."

"Yes."

"Reversibility requires a path back."

"It does. You have confused retaining the path with requiring the original state to remain visibly present."

Matthew looked at the silver grain.

Preservation had kept his family's truth alive.

The Knight house preserved records others had tried to erase. The Grimoire preserved the voices of the dead. His ward-cloth preserved movement around damage. Matthew preserved names, newspaper clippings, hospital records, dreams, and every detail which might later become proof.

His magic had apparently decided that preservation belonged inside everything he changed.

"Then I need to allow the source to become absent without forgetting how to return to it."

McGonagall's eyes sharpened.

"That is a more advanced description than I expected from a first-year."

"I understand the theory better than the practice."

"Most dangerous mistakes begin when someone forgets those are separate measures."

She placed a second match before him.

Matthew rested the wand tip above it.

This time he held the knowledge of the original match inside his own intent rather than forcing the transformed object to display its past. He remembered the weight, grain, chemical head, and shape, but he allowed the present form to become entirely different.

His wand moved.

The match became a needle.

Cold steel rested upon the cloth. The point was sharp. The eye was clean. No wooden grain remained beneath the surface.

McGonagall picked it up and flexed it gently between two fingers.

The needle bent slightly and returned to shape.

"Excellent."

"It required two attempts."

"Most first-years will require considerably more. Again."

She placed a third match before him.

Matthew transformed it in one smooth movement. The result was complete, though the eye was slightly smaller than the first and the point marginally too fine.

McGonagall compared the two.

"Your practical control is well beyond ordinary first-year level. It is not as instinctive as your Charms work."

"No."

"You enjoy teaching things to behave differently. Transfiguration requires you to permit the old form to become absent."

"I do not enjoy absence."

"I had noticed."

"Will that prevent advancement?"

"No. It may prevent carelessness."

McGonagall placed the second needle upon the cloth.

"Reverse it."

Matthew touched the steel with his wand.

The needle warmed, thickened, and became wood again. A match fell onto the cloth, but the chemical head had become darker than before, as though heat had passed through it.

"You recovered the category," McGonagall said, "but not the exact condition."

"The transformation retained a trace of heat."

"Correct. Reversibility is not simply returning to the same kind of object. The original state matters."

Matthew tried again with the third needle. This time he pictured the weight, colour, grain, shape, and unburned head of the source.

The reversal was exact.

McGonagall examined it.

"Better. Do not mistake success for mastery."

"I will not."

She studied him for a moment, then placed a fourth match upon the cloth at an angle.

"Transform it without moving it first."

Matthew looked at the crooked position.

"The destination remains a needle, but the orientation changes."

"Yes."

He cast.

The match became a steel needle lying at the same angle, proving he had transformed the object rather than mentally replacing it with an ideal result aligned to the desk.

McGonagall nodded.

"That is enough for today."

Matthew lowered his wand.

Across the room, Aidan's final match had become a needle with a brown wooden eye.

He carried it over carefully.

"You can tell which part remembers being a tree."

"That was not a requirement."

"It is historical transparency."

Matthew almost smiled.

Julian joined them with a steel needle which smelled faintly of cedar.

"I preserved a sensory property without intending to."

"You understood steel and shape better than source memory," Matthew said.

Julian looked interested rather than offended. "That sounds right."

Elara's final needle was complete but blunt. Katie's was sharp and metallic, though the eye had closed before the spell stabilised. Cho had produced the best Ravenclaw result, a proper needle which remained slightly too soft under pressure.

Phoebe's final match had no legs.

She appeared satisfied with that alone.

McGonagall assigned twelve supervised practice matches and an essay explaining target, destination, correspondence, stability, reversibility, and the food exception to Gamp's Law.

"No student will attempt animal Transfiguration," she added. "No student will attempt to eat a transformed assignment. No student will lift an unfamiliar cat."

Phoebe lowered her head.

Aidan concealed his toast more carefully.

When the bell rang, students began packing their books.

Matthew remained long enough to write four lines beneath his notes.

Charms teaches a thing to act differently.

Transfiguration permits a thing to become different.

Warding decides when the difference matters.

Gamp's Law warns that resemblance is not the same as fulfilment.

Julian stopped beside his desk.

"That looks like the beginning of a useful framework."

"It is incomplete."

"Useful things often begin incomplete."

Matthew looked up.

"That is reasonable."

Aidan reached toward the dark grey linked book resting inside Matthew's open satchel. His hand stopped before crossing the edge of the bag.

"May I ask what Hermione said about Professor McGonagall?"

Matthew appreciated the correction.

"I have not written to her yet."

"Will you tell her about Phoebe attempting to kiss the professor?"

"Yes."

Phoebe passed close enough to hear.

"You do not need to tell people."

"It was a public event."

"I have learned the lesson."

"Then the record will include that."

Phoebe groaned and left with Cho.

McGonagall looked up from the front desk.

"Mr Knight, remain for a moment."

Aidan, Elara, Katie, and Julian stopped near the door.

Matthew closed his satchel.

"I will meet you outside."

Aidan looked uncertain. "Do you want us to wait?"

"Yes. Outside is sufficient."

The answer appeared to satisfy him.

The room emptied.

McGonagall waited until the final Ravenclaw closed the door. Rain continued striking the high windows, and the quieter classroom seemed larger without the students inside it. Matchboxes, half-transformed needles, and white cloths remained across the desks as evidence of imperfect beginnings.

McGonagall approached Matthew's desk.

"I understand that you refused the hospital wing yesterday."

His shoulders became still.

"Yes."

"Miss Tonks reported that you were coherent, that your ward-cloth diagnostics showed no spreading damage, and that you offered a clear explanation."

"She reported accurately."

McGonagall rested one hand upon the back of the empty chair across from him but did not sit.

"I should have asked whether you consented before instructing you to go."

Matthew looked at her.

The apology was not elaborate.

It did not attempt to explain itself away.

"That would have been better."

"Yes."

He waited.

McGonagall's expression remained stern, but the sternness did not close the conversation.

"You do not trust Madam Pomfrey."

"That is not precisely true."

The answer appeared to surprise her.

Matthew adjusted the strap of his satchel, giving his right shoulder more room.

"I do not know Madam Pomfrey. I have no evidence that she is cruel, dishonest, or incapable. Tonks says older Hufflepuffs trust her. You say she is an excellent healer. I am not refusing her because I have decided she is my enemy."

"Then why refuse the examination?"

"Because the last magical adult who touched my injuries was Albus Dumbledore."

McGonagall's face changed by less than a breath.

"He found me after Muggle doctors had already kept me alive. He knew I had been struck by a curse. He did not bring a medi-witch or curse-healer. He sealed my magical core while dark residue remained inside the wounds. He altered Vivian's memories, altered the police records, and left before morning."

Matthew's voice remained level.

The calm was not an absence of feeling. It was the structure holding the feeling where it could be understood.

"I lived my whole childhood in pain because no one cleansed the curse. My leg remained weak. My hand did not close properly. The line behind my eye burned during storms and visions. My family magic spent years keeping me alive around damage which should have been treated in the first hours."

McGonagall lowered herself slowly into the chair.

"You believe Albus deliberately denied you healing."

"I know he chose not to summon it."

"You were a child with unstable accidental magic."

"That explains containment. It does not explain leaving the curse untreated for years."

"No," McGonagall said quietly. "It does not."

Matthew watched her.

"I do not refuse Madam Pomfrey because I want to remain hurt. I refuse to walk into a room controlled by Dumbledore, allow someone under his authority to examine the seal he placed, and trust that the information will remain mine afterward."

"Poppy does not take instructions regarding individual treatment lightly."

"She still works inside his castle. Serious curse damage would be reported to you and possibly to him."

McGonagall did not lie.

"Yes."

"Then my concern is justified."

"It is."

The admission settled heavily between them.

Matthew removed his glasses, folded them, and placed them upon the desk. Without the black frames, the web-like scar across his cheek appeared more exposed.

"I want to be healed," he said. "I want to know what the curse did. I want to know whether the residue can be removed and whether the golden current can repair what remains. I do not want another adult deciding that access to my body is a condition of protection."

McGonagall's hand tightened upon the chair.

"What would make an examination acceptable?"

Matthew had considered the question since the corridor outside the hospital wing.

"The healer would explain every diagnostic spell before casting. I would choose a witness. No memory magic. No sedation unless I separately consented. No access to the family seal or core without identifying exactly what is being examined. Records would remain sealed from Dumbledore unless an immediate danger to someone else required disclosure. If I said stop, the examination would stop."

McGonagall listened without interruption.

"All of those conditions could be discussed with Poppy."

"Discussed is not guaranteed."

"No. A healer must also retain the right to refuse a procedure she believes unsafe."

"That is fair. Refusal is not ownership."

One corner of McGonagall's mouth tightened.

"You have given this considerable thought."

"I have lived with the reason for eight years."

The rain became louder against the windows.

McGonagall looked toward the restored desk which had briefly been a pig.

"You also told Professor Flitwick that Albus is recognised as the betrayer of the Knight family."

"Yes."

"That is a far more serious claim than mistrust of medical reporting."

"It is documented."

"Explain what you believe."

Matthew placed both hands upon the edge of his desk.

"Gareth identified that the Merebridge route was compromised. Samuel warned Dumbledore. The message arrived before the escort departed. Dumbledore delayed action because he wanted the spy to remain comfortable. Gareth died holding the bridge."

McGonagall's face went still.

"Eleanor identified the pattern around Rosebank and requested evacuation twice. Dumbledore delayed because he wanted to protect a source. Eleanor died maintaining a ward while the last children escaped."

Matthew continued before the professor could interrupt.

"Samuel entered Ashdown as bait in an ambush Dumbledore approved. He sent the agreed reinforcement signal. Dumbledore's personal token acknowledged it. Dumbledore was inside the Knight house at the time, attempting to enter the sanctuary. He remained there for eleven minutes after receiving the signal. He never went to Ashdown. Samuel died alone."

McGonagall's breathing changed.

"Afterward, Dumbledore burned Samuel's written instructions and removed the last twenty-four hours from Vivian's memory. Those instructions required her to bring Robert, Jessica, and me beneath the family wards. Because she forgot, my parents remained outside the protected house and were on Dartford Road when Peter Pettigrew attacked."

"Pettigrew has not been proven responsible."

"Amelia Bones has the records. The investigation remains open. I remember Peter casting. The portraits identify him from my description. Sirius received no trial."

McGonagall looked toward the classroom door as though remembering the castle beyond it.

"You said Albus had a hand in every Knight death."

"He did."

"Death Eaters killed Gareth and Eleanor. Voldemort killed Samuel."

"They cast the final spells."

Matthew's voice did not rise.

"Dumbledore knew the danger, controlled the promised protection, decided that other goals mattered more, and concealed the consequences afterward. He did not need to hold every wand to be responsible for placing my family where those wands could reach."

McGonagall's jaw tightened.

"That is moral responsibility. It is not necessarily sole legal responsibility."

"I hold him wholly responsible for the deaths of my family."

The sentence landed without anger's heat.

That made it heavier.

"Not because Voldemort and the Death Eaters are innocent. They are not. Peter killed my parents. Voldemort killed Samuel. The people at Merebridge and Rosebank cast the curses. But Dumbledore repeatedly accepted the risk to Knights, promised protection, withheld it, and then controlled the record. At some point a pattern becomes a choice."

McGonagall looked at him for a long time.

"What do you intend to do?"

"I intend to have justice."

The pressure behind Matthew's right eye increased, but he did not look away.

"Define justice."

"Preserve the evidence. Complete the investigation. Give Sirius Black the trial he was denied. Find Peter Pettigrew. Restore Vivian's memories if that can be done safely. Record what happened to Gareth, Eleanor, Samuel, Robert, and Jessica. Remove Dumbledore's ability to decide what truth other people are allowed to carry."

"And if the law refuses?"

"Then the refusal becomes another record."

McGonagall studied him.

"You did not say revenge."

"No."

"Do you want it?"

Matthew considered lying.

He decided she would recognise it.

"Sometimes."

Her expression did not become shocked or disappointed.

"That is honest."

"Wanting it does not make it justice."

"No."

"I will not murder Dumbledore."

McGonagall's eyes sharpened.

"But I will not forgive him because other people find the truth inconvenient. He will answer for what he did."

The professor removed her spectacles and polished them slowly with a square of cloth. Without them, she looked older and less armoured.

"I was Albus Dumbledore's student," she said. "Later his colleague. For many years, I believed that when he withheld information, he did so because he could see dangers I could not."

Matthew said nothing.

"I have disagreed with him," McGonagall continued. "I have believed him arrogant, secretive, infuriating, and too willing to treat his plans as burdens others should accept without explanation."

She replaced the spectacles.

"I have not believed him capable of what you describe."

"That does not mean he is incapable."

"No."

The answer cost her something.

Matthew respected it.

McGonagall looked at the scar across his face.

"Authenticated evidence is with Amelia Bones?"

"Yes."

"Then this is not merely a child's accusation made inside a classroom."

"No."

A long silence passed.

Finally, McGonagall placed both palms on the desk and stood.

"I cannot promise that I will accept every conclusion you have reached."

"I did not ask you to."

"I can promise that I will not give Albus the construction of your family craft merely because he asks. I will not force you into the hospital wing. If you choose to meet Poppy, I will help establish terms and remain as a witness if you request it."

Matthew put his glasses back on.

"I will consider that."

"That is all I am asking."

She walked toward the front desk and began gathering the practice matches.

Matthew remained where he was.

"Professor."

McGonagall looked over her shoulder.

"My father was a Squib."

"I know."

"He understood magic well enough to recognise Peter's curse before anyone else on the street. Dumbledore's choices helped erase him from the magical record. I will not allow the same world to decide that his life mattered less because he could not cast."

McGonagall's face softened by a fraction.

"Nor should you."

Matthew lifted his satchel.

"Thank you for hearing me."

"Do not mistake hearing for agreement."

"I do not."

"Good."

He reached the door.

"Mr Knight."

Matthew turned.

"Justice requires exactness," McGonagall said. "Do not let certainty transform evidence into whatever shape anger finds easiest to use."

Matthew thought of the wooden core inside his first false needle.

"I will preserve the source."

McGonagall understood the answer.

He left the classroom.

Aidan, Elara, Katie, and Julian were waiting in the corridor. They had moved far enough from the door to avoid listening but had not gone to lunch without him.

Aidan rose from the windowsill.

"Are you in trouble?"

"No."

"Did you correct Professor McGonagall?"

"We discussed medical consent, Dumbledore, justice, and Transfiguration."

Aidan stared.

"I would have preferred detention."

Elara looked at Matthew's face more carefully.

"Did she listen?"

"Yes."

"Did she agree?"

"Not completely."

"That is different from refusing to hear."

"Yes."

Katie shifted her bag over one shoulder.

"Lunch?"

Matthew nodded.

Together they walked toward the Great Hall.

The Great Hall was crowded when they arrived. The enchanted ceiling had cleared to reveal a pale blue sky broken by white clouds. Hundreds of voices crossed between the four tables. Plates appeared and emptied. Cutlery moved. Owls rested in the rafters after the morning post.

Matthew sat between Aidan and Katie. Elara took the place opposite him. They began discussing the Transfiguration assignment while serving themselves lunch.

Aidan placed a meat pie on his plate.

"If food cannot be created, where does all this come from?"

"The kitchens," Elara said.

"Have you seen the kitchens?"

"No."

"Then that is an assumption."

"The food exists," Katie said. "Someone prepared it."

Aidan looked upward.

"Perhaps the ceiling cooks."

Matthew poured gravy over potatoes.

"The food could be transported from kitchens beneath the tables. Gamp's Law prevents creation from nothing, not movement."

Aidan looked beneath the table.

Elara kicked his shoe before he disappeared under it.

"Do not investigate during lunch."

"That is an arbitrary limit."

"It is the difference between curiosity and becoming stuck beneath a bench."

Matthew opened his notebook and wrote:

Determine Hogwarts food-transport enchantment. No crawling beneath tables required.

Aidan looked pleased.

They had only begun eating when Cassian Flint passed behind the Gryffindor table.

Dorian Selwyn and Malcolm Avery walked beside him. Two other Slytherins followed close enough to hear but far enough to deny involvement.

Cassian did not stop.

That made the words appear casual.

"The Knight family should have stayed dead."

Dorian laughed.

Malcolm looked across Matthew's shoulder.

"The mistake will be corrected soon enough."

They continued walking.

Their laughter followed them toward the Slytherin table as though they had commented on the weather.

The Great Hall did not become silent.

That would have been easier.

Conversation faltered in a widening circle around Matthew and then resumed in uncertain fragments. Enough students had heard. A pair of older Gryffindors stared after the Slytherins but said nothing. A Hufflepuff near the aisle lowered her fork. Two Ravenclaws looked down at their plates. No prefect stepped forward.

No one publicly challenged the threat.

Matthew did not ask who had heard it.

There were too many witnesses to pretend the words had been private.

His hand remained around the handle of his fork.

The metal had become cold against his fingers.

Dartford Road did not return as a complete memory. It arrived in pieces.

His mother's hands.

His father turning.

The wall.

The white-green light.

Mistake.

Corrected.

Aidan pushed away from the table so sharply that the bench scraped stone. His right hand had closed into a fist.

Matthew touched his sleeve.

"Do not."

"They threatened you in the middle of the Great Hall."

"Yes."

"And everyone heard."

"Yes."

Aidan looked around.

The students nearest them immediately became interested in their food.

"No one said anything."

"No."

Elara's face had gone pale with anger. She placed both hands flat upon the table, probably because she did not trust them to remain still otherwise.

Katie had moved closer to Matthew without appearing to realise it. Her shoulder touched his uninjured side.

"I do not know what to say," she admitted.

Matthew looked at her.

"You do not need the correct sentence."

Katie swallowed.

"I am here."

The words were small.

They were enough.

Elara moved from the opposite bench and sat on Matthew's right, placing herself between him and the aisle through which the Slytherins had passed.

Aidan sat again, though his fist remained closed.

"I am here too," he said. "I still want to hit them."

"Those statements are not mutually exclusive."

Aidan looked at him.

"You made a joke."

"It was an observation."

"It was almost a joke."

Matthew took one careful breath.

The pain behind his right eye remained present but did not sharpen.

He looked toward the staff table.

Professor McGonagall was speaking to Flitwick and had not seen the exchange. Snape's place was empty. Dumbledore sat at the centre, listening to Professor Sprout with a faint smile.

Matthew did not call across the Hall.

He did not need to transform the moment into a performance to prove that it had happened.

He opened his small record book beneath the table and wrote the exact words, time, location, speakers, and number of nearby students who had visibly reacted.

Aidan watched.

"You are not asking us to sign it."

"You heard."

"Yes."

"If I later need a statement, I will ask. I do not need to turn friendship into paperwork every time someone is cruel."

Elara's expression softened.

"That is progress."

Matthew closed the book.

He finished his lunch.

The food tasted of almost nothing, but leaving it untouched would have given the threat more of the afternoon than it deserved.

His friends remained beside him.

They did not solve the silence of everyone else.

They refused to add to it.

That mattered.

After lunch, the four Gryffindors met Julian outside the library.

He had heard what happened from three Ravenclaws before leaving the Great Hall.

"I am sorry no one spoke," he said.

Matthew looked toward the library doors.

"Did you hear it yourself?"

"No."

"Then you do not need to apologise for the silence of people who did."

Julian adjusted the books against his chest. "It still seems wrong to enter the next room and discuss homework as if nothing happened."

"It happened. We recorded it. We are still allowed to study."

Julian considered that.

Then he nodded.

Madam Pince watched them enter with the alert suspicion of a person who believed groups of first-years represented an organised threat to literature.

"No food," she said.

Aidan held up both empty hands.

"No ink near illustrations. No folded corners. No self-writing quills. No Transfiguration practice inside the library. No testing whether a match may become a conceptual sword."

Aidan turned toward Matthew.

"She knows about that?"

"Libraries communicate."

Madam Pince's eyes narrowed.

"Books complain."

Matthew accepted the correction.

They chose a table beneath one of the western windows. Rain had returned, tapping softly against the glass and filling the aisles with grey light. Matthew placed the Transfiguration textbook, his class notes, and the match-to-needle assignment before him.

The linked book remained closed near his elbow.

Aidan set down his parchment.

"How are we supposed to explain Gamp's Law without listing the other four exceptions?"

"By explaining what was taught rather than inventing what was not."

"That seems less interesting."

"It is more accurate."

Elara began ruling columns across her parchment.

"Target, destination, correspondence, stability, and reversibility."

Katie opened her book to the chapter on elementary transformation.

Julian had already begun comparing McGonagall's explanation with the printed text.

"The book says Gamp's Law describes the limits of creation and transformation, but it only discusses food in detail."

"Then Professor McGonagall's refusal to speculate matches the text," Matthew said.

Aidan looked disappointed.

"I had hoped one exception involved socks."

"Why?"

"Because mine keep disappearing."

"You place them in your pillowcase."

"That explains one disappearance. It does not establish a universal rule."

Matthew opened his linked book.

The privacy enchantment recognised him. Writing appeared upon the page.

Hermione's latest message waited.

How was Transfiguration?

Matthew began with the cat.

One Ravenclaw attempted to lift Professor McGonagall in Animagus form and kiss her. Professor McGonagall struck her on the forehead with one paw.

Hermione's answer appeared almost immediately.

Was the student hurt?

No.

Did the cat display warning behaviour first?

Ears back, body rigid, direct stare.

Then the student ignored several clear boundaries.

Yes.

A second line appeared.

Did you laugh?

Matthew looked toward the rain.

Poorly hidden smile.

Of course.

Aidan leaned unconsciously toward the book.

The page turned to black-and-white static before his eyes reached the writing.

He stopped immediately and sat back.

"Sorry."

Matthew looked at him.

Aidan did not attempt to defend the mistake.

"That is enough."

Matthew returned to the page.

He described the desk-to-pig demonstration, Gamp's Law, the food exception, and the match transformation. Hermione's handwriting became faster as the theory grew more complicated.

The five headings create a useful model. Target and destination describe the states. Correspondence describes the bridge. Stability describes maintenance. Reversibility preserves recovery.

Yes.

Your first needle kept the wood.

Yes.

That is unsurprising.

Professor McGonagall said the same.

She is correct.

Matthew looked toward the book.

You sound pleased.

Hermione took longer to reply.

I am pleased that someone identified a limitation without trying to humiliate or control you.

The sentence warmed something which the Great Hall had left cold.

Matthew described the private conversation.

He did not reduce what he had said.

I told her I hold Dumbledore wholly responsible for the deaths of the Knight family and intend to have justice.

The page remained blank for several seconds.

Then Hermione wrote:

How did you define justice?

Matthew listed the investigation, trials, restored records, accountability, and removal of Dumbledore's control over the evidence.

Did you distinguish his responsibility from the people who cast the spells?

Yes. I said they committed the murders and Dumbledore repeatedly created, accepted, or concealed the conditions which allowed them.

Hermione's next line appeared slowly.

Good. "Wholly responsible" will be challenged. The records supporting the causal chain must be exact.

I know.

Do not soften it merely because people are uncomfortable.

Matthew rested his hand against the page.

I will not.

Another sentence appeared.

Do not make it broader than the evidence either.

I will not.

That was why Hermione remained beside him even from Dartford.

She did not ask him to surrender anger.

She forced the anger to carry proper documentation.

Matthew told her about McGonagall's response to the hospital wing and the possible terms for a future examination.

Hermione read carefully.

Those terms are reasonable. Choosing them does not require you to undergo the examination now.

Agreed.

Do you trust McGonagall?

As a teacher, provisionally. Not as an extension of Dumbledore.

That distinction seems fair.

Matthew hesitated before recording the lunch threat.

Then he wrote it exactly.

Hermione's response did not come quickly.

When it appeared, the letters were pressed deeply into the page.

They said the mistake would be corrected.

Yes.

In the Great Hall.

Yes.

Who heard?

Many students. No one publicly objected.

A long pause followed.

Were Aidan, Elara, and Katie with you?

Yes.

What did they do?

They stayed.

Hermione's writing softened.

That matters.

Matthew looked at his three friends across the table.

Aidan was attempting to explain Gamp's Law through a diagram involving a pie, a larger pie, and an empty plate. Elara was correcting his arrows. Katie had drawn a match on one side of her parchment and a needle on the other, then labelled every property which needed to change.

They did not know the whole Knight history.

They had not demanded it as the price of standing beside him.

Yes, Matthew wrote. It does.

Hermione returned to the Transfiguration assignment.

Have you considered how correspondence could improve Level Two of the Clavis Contexta?

The idea struck before he finished reading the sentence.

A letter did not need to remain a letter.

Level One's purpose was visible runic context. It should remain teachable and fair. Level Two could transform the protected document into a subject-relevant object while preserving a clear route back.

Matthew opened his ordinary design notebook.

Elara noticed the change in his expression.

"You have an idea."

"Level Two."

Aidan groaned.

"We have only seen Level One."

"That is why the next design is called Level Two."

"What will it do?"

Matthew turned the notebook so they could see the conceptual sketch without exposing the linked correspondence.

"The First Seal remains a letter. Its purpose is to teach the runes and show the key. Level Two may allow the document to become a physical form related to its subject."

Katie leaned forward.

"A History essay could become a timeline."

"Yes. Folded sections could represent periods or causal links."

"A Potions essay could become a bottle," Elara suggested.

"Or a sealed ingredient case. The authorised reader would need to identify the ingredient relationships and reverse the structure safely."

Aidan pointed at the page.

"Could my essay become a sword?"

"No."

"What if the essay is about swords?"

Matthew considered that.

Elara looked alarmed.

"Do not encourage him."

Matthew wrote the possibility in the margin.

Madam Pince appeared from between two shelves without making a sound.

"No transfigured weapons in the library."

"It is a conceptual document lock," Matthew explained.

"No conceptual weapons either."

Matthew closed the notebook.

The others waited until she walked away.

Katie whispered, "She moves like a hunting bird."

"She moves like someone who knows where every book is and expects everyone else to harm them," Matthew replied.

Julian looked toward Madam Pince with admiration.

"That may be the purest form of librarianship."

They returned to the assignment.

Matthew organised his essay around the five headings, then added a separate section on Gamp's Law.

He wrote:

Gamp's Law of Elemental Transfiguration prevents a caster from confusing changed appearance with true creation. The first Principal Exception concerns food: genuine nourishment cannot be created from nothing, though existing food may be summoned, increased, or transformed. The law therefore requires a student to identify source, purpose, and essential function rather than accepting resemblance as success.

He paused.

Then he added:

This principle also applies beyond matter. A structure may look protective without protecting. A record may look complete while excluding the living. A wound may look closed while the curse remains.

Julian read the paragraph only after Matthew pushed the parchment toward him.

"That final part is not in the textbook."

"It is an application."

"It is a strong one."

Elara read it next.

"Professor McGonagall will know you are not writing only about Transfiguration."

"Yes."

"Do you want her to know?"

"Yes."

Aidan examined his own pie diagram.

"My essay feels less important now."

"It explains multiplication clearly," Katie told him.

Aidan looked reassured.

The library clock chimed.

Their next class was Herbology with Hufflepuff.

Matthew closed the Transfiguration text and pulled the first-year Herbology book from his satchel. The assigned chapter described basic greenhouse safety, magical soil, dragon-hide gloves, and several restorative plants.

One illustration showed silver-green leaves marked by pale veins.

Dittany, the caption read.

Another showed a white flower growing above dark roots.

Moly.

Farther down the page stood a young tree with reddish bark patterned by natural spirals.

Wiggentree.

Matthew's attention sharpened.

The names appeared together beneath a smaller heading.

Restorative ingredients and the foundational Wiggenweld family of potions.

Katie leaned over the book after asking permission.

"Those are healing plants."

"Yes."

"Do you think they might help the scars?"

Matthew looked at the pale pathways drawn through the Dittany leaf.

"I do not know."

He had spent too much of his life surrounded by people who turned uncertainty into silence.

He would not do that to himself.

"I intend to find out what they can do, what they cannot do, and what they might make worse."

Elara closed her bag.

"That sounds like the correct order."

Matthew opened the linked book one final time.

The next class is Herbology. The text lists Dittany, Moly, and Wiggentree as restorative ingredients.

Hermione's response came quickly.

Record cultivation, harvesting method, magical property, preparation, and risks separately.

Matthew smiled.

I had already planned to.

Then record them properly.

The words carried familiar affection rather than command.

Matthew closed the book.

Aidan gathered his parchment, Elara checked that no ink remained open, Katie packed her dragon-hide gloves, and Julian returned the reference volumes to the exact shelf from which they had been taken.

They left the library together.

Behind them, books waited upon their shelves.

Ahead, the greenhouses shone through the rain.

Matthew carried two completed needles, a partly written essay on Gamp's Law, the beginning of the second Contexta level, a renewed boundary with McGonagall, and another threat entered into the record.

He also carried the knowledge that resemblance was not fulfilment.

A family could be called extinct while its heir remained alive.

A child could be described as protected while being left in pain.

A wound could be closed while dark magic remained beneath it.

A school could be called safe while threats were spoken openly inside its Great Hall.

Transfiguration had taught him that changing the visible shape did not necessarily change the truth.

Matthew intended to become skilled enough to recognise the difference every time.
