The post-Christmas air in the Hogwarts corridors was thin and cold, the stone walls radiating a familiar chill that even warming charms couldn't quite chase away. It was late afternoon, and the golden light of the setting sun was filtering through the high Gothic windows, striping the polished stone floor with long, dusty shadows. James Potter, Sirius Black, Remus Lupin, and Peter Pettigrew—the Marauders—were strolling through a deserted third-floor corridor, their arms linked, discussing the imminent end of the holiday break and the cruelty of upcoming assignments.
"I'm telling you, Moony, that new essay topic on the ethical uses of polyjuice is a load of rubbish," Sirius complained, shaking his head dramatically. "It's clearly just an excuse for Cleen to try and catch a student attempting an illegal transformation."
"Or," Remus countered, a faint, tired smile on his face, "it's a simple essay, Padfoot. You just don't want to write it. Besides, the only one who needs to worry about illegal transformations is Echo, and he does them for fun."
"Exactly," James agreed, adjusting his robes. "Speaking of which, has anyone seen our resident menace since he got aggressively hugged by that Durmstrang gorilla?"
Peter, clinging nervously to Remus's arm, squeaked, "He said he needed a decade of solitary confinement to recover from the squishiness."
They all shared a laugh, the sound echoing slightly in the empty corridor. It was James who spotted it first. "Hey. Look at that."
He nudged Sirius, drawing their attention to a break in the shadows about twenty feet down the hallway, near an unused tapestry. Curled up asleep on a plush, velvet runner—a piece of forgotten decor that must have dated back centuries—was a Kneazle. It was a magnificent creature, about the size of a bobcat, with the tufted ears and long tail characteristic of the breed. But its fur was unlike any Kneazle any of them had ever seen. Instead of the usual spotted or tabby pattern, this creature's fur was a shimmering, soft black—a color that seemed to absorb the light rather than reflect it. As they watched, James reached out to scratch a faint, phantom itch behind his ear, the gesture completely unconscious. The Kneazle's eyes, which had been barely open, snapped shut. Instantly, the black fur on its entire body flushed a dark, annoyed maroon.
"Did you see that?" Sirius whispered, his voice laced with the kind of excitement usually reserved for pulling off a complex prank. "Its fur changed color!"
Remus nodded, his intelligent eyes fixed on the animal. "It's reacting to James's gesture. Maybe a very sensitive, mood-reactive breed? It certainly looks magical."
The four boys slowly approached, their footsteps muffled by the runner. They stopped a few feet away, watching the creature warily.
"Look, it's going back to neutral black now," Peter murmured.
Just as he spoke, Sirius leaned down and gave a soft, wolf-like woof—a noise he often made when trying to cheer up Remus. The Kneazle's eyes shot open, and its black fur instantly snapped to a vibrant, outraged crimson. It let out a sharp, high-pitched hiss that sounded uncannily like a very annoyed, muffled swear word.
"Oh, that's not right," James whispered, now openly grinning. "That is exactly the color of Echo's hair when he's furious."
Remus's eyes widened, a sudden, cold wave of realization washing over him. He lowered his voice, his gaze unwavering as he stared at the spitting, crimson-furred creature.
"The color changes based on emotion," Remus stated, the words slow and deliberate. "The complexity of the change, the intensity of the hue… and the absolute precision of the emotional trigger. It's not a reaction to magic, or a natural trait, or a mood ring, is it?"
Sirius finished the thought, his voice breathless with a combination of dread and utter fascination. "It's Echo. He didn't transfigure himself into a creature; he transfigured his consciousness into a familiar form using that insane Beast Magic of his, didn't he?"
James stared at the brilliant, furious Kneazle. "He's done it again. He's found a new way to be a curious lunatic." He sighed, but the corners of his mouth were twitching with amusement. "Alright, Echo. Come on, you big magical cat. The joke's over. Transform back."
The crimson Kneazle simply stared back at him, its eyes—which were a startling, familiar ice-blue—blazing with contempt. It let out another long, sustained hiss that ended in a sound suspiciously like a throat clearing.
"Echo, seriously," James insisted, dropping his voice to a coaxing level. "It's us. You know we don't mind. Just pop back to normal. We can go find you a bucket of eel guts or whatever it is you eat."
The Kneazle responded by calmly turning its back on them, raising its long, tufted tail in a gesture of utter, regal dismissal, and settling its nose on its paws. The crimson fur on its back slowly began to soften, fading to a weary, neutral gray—the precise shade of his hair when he was utterly exhausted.
"He's ignoring us!" Peter squeaked.
"Well, that's certainly Echo," Sirius chuckled, kneeling down. "Alright, mate. If you want to play cat, we'll play cat."
The rest of the afternoon was spent in surreal, quiet chaos. The four Marauders used the color-changing Kneazle as their personal, furry mood indicator. They scratched it gently behind the ears, eliciting a soft, contented rose color. James tossed a small, shiny galleon across the floor, and the Kneazle's fur snapped instantly to a triumphant emerald green as it leaped, batting the coin across the floor before losing interest. Sirius tried to feed it a sausage from the Great Hall, and the Kneazle's fur turned a disgusted dark blue before it spat the food out. They spent the better part of an hour trying to get it to chase the rat (Peter), which only made the Kneazle's fur cycle between bored gray and annoyed crimson. It was fun, bizarre, and perfectly fit the chaotic tenor of their friendship with Echo. The Kneazle tolerated them with a quiet, judgmental patience, allowing them to stroke its fur and occasionally curling up on Remus's lap when his gentle presence made the Kneazle's fur glow a deep, trusting lavender. Finally, as the last remnants of light faded from the sky and the dinner bell was about to ring, James stood up and dusted off his robes.
"Alright, time to wrap this up," James said briskly. "Dinner will start soon, and Madam Pince will have a fit if she sees a giant mood-cat running around the non-Restricted Section. Come on, Echo. The show's over. Time to be human."
James snapped his fingers and pointed his wand at the Kneazle, offering a familiar, non-verbal Transfiguration spell to encourage the reversal. Nothing happened. The Kneazle—curled securely on Remus's lap, its fur a calm, sleepy gray—didn't twitch a whisker.
Sirius frowned. "Okay, that's weird. Try again, Prongs."
James repeated the gesture, focusing his intent, but the result was the same: the Kneazle merely blinked its ice-blue eyes slowly.
Remus, his hand automatically stroking the creature's soft back, felt a knot of dread tighten in his stomach. "Maybe it's not Transfiguration, James. It's his Beast Magic. Echo, if you can hear me, just think the change. You can do it."
The Kneazle stretched languidly, yawned, and then—to their collective horror—began to groom its paw with a long, wet, and utterly animalistic tongue. The sleepy gray of its fur did not waver.
James felt the humor instantly drain from the situation, replaced by a cold, sharp panic. "It's not doing anything," he whispered. "He's not even trying to do anything, Padfoot."
"Maybe he's just being dramatic," Peter offered weakly, though his voice was trembling.
Sirius, however, had gone completely pale. He knelt beside Remus, placing a trembling hand on the Kneazle's shoulder. He looked closely into the animal's intelligent eyes, searching for the arrogant, mocking intelligence of his friend. He found only the deep, slightly detached patience of a high-functioning predator.
"His fur is gray, Remus," Sirius said, his voice low and tight. "Completely gray. That means he's exhausted, but not emotionally engaged. He's not reacting to the urgency of us asking him to change back. He's reacting to us like… like a cat reacting to a breeze. He's physically Echo, but…"
Remus finished the sentence, his hand tightening in the fur. "He's mentally a Kneazle. He pushed his mind into the form, and now he can't pull it back. He's not being dramatic, he's… he's forgotten how to be human."
A wave of profound, sickening fear washed over the four boys. Their genius, self-proclaimed Alpha friend, the source of half their ongoing problems, was now a plush, color-changing housecat.
"We left him in this state for too long!" James cried, running a hand through his hair. "We played fetch with him! We fed him! We encouraged the Kneazle's instincts! Merlin, what do we do?"
Peter was already dissolving into quiet tears. "His brain… It's a magical cat brain now! We turned him into a magical cat!"
Sirius grabbed the terrified Peter and shook him, his own panic barely contained. "Stop it, Wormtail! We can fix this! We have to fix this! Who knows Transfiguration better than Echo?"
"Minerva!" Remus gasped, his eyes flying open. "Professor McGonagall! She's the greatest Transfiguration master alive! She has to be able to reverse a self-Transfiguration! Bring him to her office now!"
But a fresh wave of panic hit James, his voice cracking with desperation. "What if it's too late, Moony? What if his consciousness, his Echo-ness, has permanently dissolved into the creature's instincts? What if we've lost him? What if we're too late and we accidentally turn our friend into a highly intelligent, mood-based pet?"
The crimson of the Kneazle's fur briefly flashed to a bewildered, shimmering violet before snapping instantly back to a sleepy gray, showing the fleeting remnants of Echo's own internal confusion at their distress.
"We don't have time for this!" Sirius shouted, scooping the Kneazle up off Remus's lap. The massive cat, surprisingly heavy, didn't struggle; he merely rested his head on Sirius's arm, his fur a calm, neutral gray. "We're taking him to Minerva! Now!"
The four boys, adrenaline surging through their veins, ran. They sprinted through the deserted corridors, Sirius carrying the bizarrely calm Kneazle, the other three Marauders scrambling to keep up. They skidded to a halt outside Professor McGonagall's office, their breathing ragged and their faces pale with terror. James threw open the door, and they tumbled inside, interrupting the stern-faced witch who was grading papers at her desk.
"Professor!" James gasped, completely out of breath. "It's Echo! He's a cat!"
"A magical cat!" Sirius panted, holding up the Kneazle, whose fur was now a vivid, flustered pink from the sudden, jarring motion and loud noises.
"And he won't change back!" Remus added, leaning against the doorframe, trying to catch his breath. "We think we broke his brain, Professor! He thinks he's a Kneazle! We were having fun with him, and now he won't do anything!"
Peter was whimpering behind Remus. "It's our fault! We played with him for too long! He's a magical cat forever!"
Professor McGonagall, who was already accustomed to the catastrophic nature of the boys' lives, simply pushed her half-moon spectacles up her nose and regarded the hysterical cluster of students, the panicked human babbling, and the flustered, pink-furred magical cat. She held up a single, sharp hand, cutting through the noise like a well-placed Silencing Charm.
"Silence!" she commanded, her voice ringing with authority. "One at a time! Sit down, all of you! You, Black, place that creature gently on the floor. Now, start from the beginning, Mr. Lupin. Slowly. And try to refrain from using the words 'cat,' 'brain,' or 'forever' if you can manage it."
"Professor, it was my fault," Remus said, pushing himself off the doorframe and stepping forward, his voice tight and desperate, overriding James's attempt to speak. The Kneazle, resting peacefully in Sirius's arms, was now a warm, soft rose color, reacting to Remus's proximity and distress. "We found him—found it—in the corridor. It has fur that changes color with emotion, exactly like Echo's hair. We thought it was a new way he was experimenting with his Beast Magic, a self-Transfiguration gone… stable."
Remus swallowed hard, his eyes glued to the Kneazle. "We played with him, Professor. We encouraged the animalistic behavior. We thought it was fun. But when we tried to make him change back, he wouldn't. He just… started grooming himself. His fur turned gray, Professor. That means exhausted and disengaged. We realized he didn't just change his body; he pushed his consciousness into the form, and now he's mentally a Kneazle. We left him in that state for too long."
He took a trembling step closer to her desk, his voice cracking. "Professor, you're the best Transfiguration master alive. Please, you have to reverse it. If he stays like this, the change could become permanent. We can't let him stay a magical cat forever. His genius, his Echo-ness, we need to pull it back!"
Peter let out a high-pitched, choked sob, clutching his hands together. "B-but what if you bring the body back, Professor, and his mind doesn't follow? What if we get Echo back, but he's just… a Kneazle in a boy's body? W-what if he's just a cat-brained vegetable?"
The horrifying, clinical possibility sent a fresh wave of sick panic through James and Sirius. James immediately slapped a hand over his mouth, his eyes wide with terror, while Sirius's arms, holding the sleeping Kneazle, began to shake violently.
Professor McGonagall's expression hardened, her jaw setting with grim determination as she took in the boys' sheer terror. She rose from her desk, her towering form commanding immediate attention. "Silence, all of you," she commanded, her voice firm and ringing. "Mr. Pettigrew, that is an alarmist and frankly unhelpful assessment. You are all students of Transfiguration; you know the principles of mass and mental substitution. There is always a way. We will not panic. This is not the end."
She walked around the desk, her gaze sweeping over their distraught faces, trying to project a calm she didn't quite feel.
"We will contain the creature," she continued, speaking slowly and deliberately. "We will examine the magical signature. If necessary, we will attempt a forceful, focused counter-Transfiguration. Even if, hypothetically, Mr. Echo's core consciousness has suffered a degree of magical shock—a temporary vegetative state, as you so dramatically put it, Mr. Pettigrew—then we will find a way to repair it. We will fix this, gentlemen. Together. But you must be calm."
Her attempt at reassurance had the opposite effect. Remus, the usually stoic one, finally broke. He staggered back, his face crumpling, and he sank down to his knees, burying his face in his hands as quiet, ragged sobs shook his frame.
"A vegetable," Remus whispered, the sound thick with self-recrimination. "We were having fun, Professor. Just having fun. And now I've… I've helped turn my friend into a brain-damaged magical housecat."
The three other Marauders gathered around Remus instantly, their fear now mixed with crushing guilt.
"Oh, there you are, you little rascal. I've been looking all over for you."
The voice was calm, utterly out of place, and sounded exactly like the one boy who was currently a magical cat cradled in Sirius's arms. The four Marauders and Professor McGonagall instantly snapped their heads toward the open doorway. Leaning casually against the doorframe stood Echo. He was wearing his usual dark robes, his hair a tired, thoughtful shade of gray, and he looked perfectly human, if a little exhausted.
Sirius, his arms still clamped around the Kneazle, let out a startled yelp. The Kneazle, hearing the voice of its master, instantly leaped from Sirius's arms with a joyful chirrup. It shot across the room and sprang onto the chest of the standing boy, nuzzling its head enthusiastically against Echo's chin. Its fur immediately flushed a vibrant, contented rose.
Echo chuckled, gently petting the magnificent, rose-furred Kneazle that was now purring loudly against his neck. He looked up from the cat and surveyed the scene: four boys frozen in various states of shock and hysteria, and a Professor with her hand hovering over her wand, her face a perfect mask of utter confusion.
"What?" Echo said, adjusting the Kneazle's grip on his shoulder.
The four Marauders began to babble incoherently.
"But—you—the cat—" James sputtered, pointing wildly between the purring animal and Echo.
"The color—your hair—we thought—" Sirius stammered, shaking his head as if trying to clear water from his ears.
"Forever—vegetable—oh, Merlin, I'm so sorry," Peter wailed, clinging to Remus.
Echo raised an eyebrow, the tired gray of his hair softening slightly with amusement. "Take it easy, guys. Don't you usually babble like a group of drunk geese on the third Tuesday of every month? And it's only a Saturday."
Remus, finally pulling himself together, staggered toward Echo. He pointed a trembling, accusatory finger at the Kneazle, then at Echo, his mouth working furiously, but only managing a series of choked, half-formed sounds. He shook his head, unable to articulate the central, terrifying contradiction.
James, finally finding his voice, pointed an accusing finger at Echo, his breathing still ragged. "But why were you here, Echo? Why were you in the corridor? Why did you let us think that was you?"
Echo looked at James with an expression of honest, utterly bewildered confusion. The amused yellow in his hair snapped back to a tired, neutral gray. "Why was I here? Is it a crime for me to visit my favorite Professor in the entire school?" Echo looked from Remus's distraught face to the speechless Professor McGonagall. "Professor?" he asked, a touch of genuine confusion entering his voice. "A little help? I seem to have missed the inciting incident."
Professor McGonagall slowly lowered her wand, her sharp eyes moving between Echo and the magical cat purring contentedly on his shoulder. "I confess, Mr. Echo, I would also like an explanation," she said, her voice dry and clipped. "But what I have managed to gather from this alarming display is that your friends believed that Kneazle was you."
Echo took a moment, his brow furrowing as he put the pieces together—the color changes, the Marauders' hysteria, Remus's tears. A slow, self-aware smile spread across his face.
"Oh," Echo said, his hair flashing briefly to an amused, sharp yellow. "Oh, that makes sense. I can see where the confusion is."
McGonagall stepped forward, her hands now planted firmly on her hips. "While the sight of four panic-stricken young men is often illuminating, Mr. Echo, I must ask: Why is there a Kneazle with mood-changing fur like your hair? And where did you get it?"
Echo ran a hand gently over the Kneazle's purring fur, which was still a warm, contented rose color. He turned his attention from the Professor to the four still-shaking boys.
"Gentlemen," Echo said, his voice calm and patronizing, the gray in his hair settling into a thoughtful, neutral hue. "Cast your minds back. Second year. Start of the term, I believe. Does anyone recall a certain prank involving my favorite hair care product and a questionable, color-changing potion?"
James and Sirius exchanged a sheepish, nostalgic glance.
"Ah, the Chromatic Conditioner Caper!" James exclaimed, a wide grin spreading across his face as the sheer terror of a moment ago vanished. "That was a classic, mate! You looked utterly fabulous for weeks! Still do."
Sirius nodded enthusiastically, running a hand through his own dark hair. "It was a stroke of genius, Echo! We thought you'd lose your mind, but you just incorporated it into your entire chaotic persona! Best two galleons I ever spent on dodgy potion ingredients."
Remus, however, shook his head, his face still pale. "I had nothing to do with that one, I swear. I was with Lily in the library when they planned it."
The Kneazle, resting on Echo's shoulder, turned its head and fixed its ice-blue eyes on James and Sirius. Its fur snapped instantly to a vibrant, unamused gray. Echo mirrored the expression, his own gray hair holding the same dull, weary hue.
"Let me remind you of something, gentlemen. That whole episode—the color-changing hair—happened after a Dementor kissed me. I was, at the time, devoid of all pleasant memories, stripped down to an empty, hollow shell of a person."
The Marauders flinched visibly, the memory of Echo's near-death experience—and the horrifying sight of his soulless state—hitting them with fresh force. Remus closed his eyes, his pale face draining further of color.
Echo continued, his voice utterly flat. "My emotions, my internal landscape, were a void. And the first thing that managed to provoke a reaction from that empty husk of a soul was your prank. The first emotion I felt was fury, directed entirely at the four of you."
He paused, a dark, dangerous energy beginning to swirl around him. "Do you recall what I did next, after seeing my hair?"
Peter gulped, his eyes wide with fear. "You… you furiously hunted us down to Gryffindor Tower. And tried to… end us with a griffin." He shivered violently. "I remember that. I even… peed myself a little."
Echo gave a short, hard nod. "Precisely. But I spared you the indignity of being eaten. I decided a quick death was too kind. I chose to instead 'throw hands,' as you put it, with all four of you simultaneously."
James winced, rubbing the back of his neck and looking anywhere but at Echo. "The whole school didn't let us live down the fact that we 4v1 a second year and lost."
"Right," Echo drawled, his voice flat. "Well, I was sitting around a bit ago, and I thought, 'Huh. If those three nitwits could procure such a dangerously potent color-changing potion with such ease, who's to say some other, even more brain-dead moron couldn't do the same and cause a school-wide epidemic of mood-ring hair?'" He tapped the Kneazle gently on the nose. "The thought of an entire school of students with involuntarily expressive hair—imagine the psychological damage!—was frankly unconscionable. So," Echo continued, his tone shifting to one of scientific detachment, "I decided to try and find a counter-measure that removed the effect without resorting to the only known natural cure."
Professor McGonagall stepped forward, her professional curiosity overriding her annoyance. "And what, Mr. Echo, is the natural way?"
Echo sighed dramatically. "To shave your head bald, Professor. The potion bonds with the hair follicle, not the skin. I am not shaving my head bald in the middle of January, and frankly, I like my long hair since Skate gets to braid it."
He gestured to the Kneazle. "So, I simply took a willing test subject—this fine Kneazle, whose name is actually Lycan—brewed a slightly stronger version of the same potion, and applied it. He was in great control. Now I have to figure out an alternative countermeasure without shaving the cat. The only reason I haven't started that work yet is that the spot where I left the Kneazle to let the potion set in permanently suddenly vanished." Echo frowned, a look of genuine annoyance crossing his features. "He was supposed to be waiting by the third-floor gargoyle. So I've been looking all over the school all day. Why did something happen with the Kneazle?"
The four Marauders and Professor McGonagall stared at him, their earlier fear transforming into profound, exhausted stupefaction.
James finally broke the silence, his voice a disbelieving whisper. "You mean… You didn't Transfigure yourself. You just permanently afflicted an innocent creature with your own affliction, and then lost it, causing us to believe you had become a brain-damaged housecat?"
Echo blinked, the gray in his hair flashing briefly to an offended yellow. "Afflicted? It's a magical enhancement! And technically, you caused my affliction, James! And I didn't lose him. He merely…left, and by the looks of it. Your four took him." Echo shrugged, the Kneazle—Lycan—purring contentedly on his shoulder. The tired gray in his hair was tinged with a thoughtful, analytical blue. He looked at the four bewildered boys and the highly annoyed Professor.
"And of course I didn't transform myself into a Kneazle. The reason, even if I was out of my mind on some kind of emotional overload, is simple, gentlemen. It's a matter of magical physics. You cannot transfigure yourself—or any object, for that matter—into a magical creature. It is one of the immutable rules of Transfiguration. The fundamental magical signature is simply too complex to be replicated or sustained by a standard wizard's core."
He gestured to the Kneazle with his chin. "This is a Kneazle. It is a magical animal with a unique, self-sustaining signature that governs its inherent abilities, including enhanced intelligence, the ability to detect unsavory persons, and the ability to see and hear through certain magical charms and illusions. To successfully transfigure me into him would require the spell to not only reshape my entire physical form and magically rewrite my DNA, but also to instantaneously and permanently generate that distinct, non-human magical core from thin air."
Echo paused, letting the information sink in. "And since my Beast Magic allows me to do a bunch of admittedly weird stuff with living things, I can confirm: it's impossible. The closest I can get is parts of different non-magical animals—like an owl's claws or a wolf's snout. But I can't generate a second, separate magical signature. If it were possible, the market would be flooded with fake magical creature parts. Everyone would be casually Transfiguring Basilisks and Dragons into existence. It would become the new Avada Cadavra. I've tried. Of course, I've tried. The immediate feedback is a magical core screaming at you to stop violating the laws of nature. It cannot be done. I merely have a magical cat that you boys accidentally treated like a brain-damaged version of me."
Professor McGonagall let out a sound that was half-gasp, half-choked laughter, clutching her hand to her chest. "Mr. Echo! You—you are incorrigible! You used an animal to solve your problem, you lost the animal, and your friends' subsequent hysteria was based on their own guilt!"
"Well, yes," Echo confirmed, petting the Kneazle again. "But back to my point. I found him. Why were you all here?"
The four Marauders, who had been listening to Echo's lengthy, scientific explanation with growing degrees of relief, exhaustion, and embarrassment, moved as one. They converged on Echo, their earlier fear completely transforming into overwhelming fraternal relief. James was the first to reach him, wrapping his arms around Echo in a tight, bone-crushing hug. Sirius instantly joined, pushing the still-purring Kneazle, Lycan, aside to clamp his arms around both of them. Remus, his face still streaked with tears of self-recrimination, dissolved into the center of the embrace, and Peter scrambled to add his slight weight to the tangle.
"You glorious, insane bastard!" James roared into Echo's hair, squeezing him tightly. "We thought we'd turned you into a vegetable!"
"Never, ever do that again, Echo!" Sirius demanded, his voice thick with emotion, his eyes wide. "I almost had a heart attack! We were actually planning your funeral!"
Remus leaned his head against Echo's shoulder, a raw, choked sob escaping him. "I was so scared, Echo. Please, promise me you won't do anything that insane again. You're too important to us!"
Echo, pinned by the unexpected force of four panicked teenagers, let out a surprised oof. His hair snapped instantly to a flustered, confused pink, mirroring the one Gungnir had caused earlier.
"W-what?" Echo sputtered, his voice muffled by James's robes. The Kneazle, Lycan, had been dislodged and was now clinging stubbornly to Echo's head. "I already told you, I didn't Transfigure myself! It's a magical impossibility! And I did not ask for a second Alpha-level hugin thee same week! Release me now!"
James, Sirius, Peter, and Remus only squeezed harder, the profound relief overriding their ability to process his words.
Finally, Echo managed to twist his head enough to address Remus. "Moony, I promise I will never transfigure myself into a magical cat or any magical creature again. As for not doing anything insane, I cannot make that promise, as the definition of 'insane' is highly subjective, especially for me."
The Marauders finally loosened their grip, stepping back to let Echo breathe. Echo leaned against the doorframe, adjusting his robes and gently pulling Lycan off his head, his flustered pink hair slowly fading back to black. He looked at the faces of his friends—their eyes red, their expressions raw with lingering terror—and his own weary expression softened with a strange, unfamiliar guilt. He turned to Professor McGonagall, who was watching the scene with a look of profound, exhausted bewilderment.
"Professor," Echo said, his voice quiet and earnest. "I'm still very confused, and now I am mentally exhausted."
Professor McGonagall let out a long, shuddering sigh and rubbed the bridge of her nose.
"Mr. Echo," she said, her voice dry and utterly devoid of energy. "I, too, am confused. I am confused by the fact that the greatest minds of your generation have mistaken a cat for a brain-damaged version of their friend. I am confused by your constant proximity to life-altering chaos. I also am mentally exhausted."
She pointed a firm finger at the office door. "The dinner bell has rung. All five of you—including the Kneazle—are leaving my office right now. You are going to head to the Great Hall, you are going to eat a warm supper, and you are going to put an end to this entire bizarre episode. Before your food gets cold, and before I decide to assign all five of you a ten-foot-long essay on the philosophical implications of magical consciousness transfer."
Echo bowed his head, a ghost of a smile on his lips. "Understood, Professor. And my apologies for the unnecessary dramatics. It was all unplanned."
He turned and walked through the doorway, the Kneazle, Lycan, settling comfortably back onto his shoulder, its fur a calm, contented rose. The four Marauders, still pale but infinitely relieved, stumbled out of the office and into the corridor, following the retreating figure of their friend. McGonagall stood in the center of her office for a long moment, watching their departure. She sighed again, retrieved her wand from her desk, and with a simple, focused Evanesco banished the faint puddle of Peter's earlier tears from the Persian rug. She looked at the closed door, muttered "Incorrigible," and sat down heavily to resume grading the pile of essays.
