Harry had barely closed the dormitory door behind him when he found himself surrounded.
Draco appeared like a ghost at his right elbow, Theodore at his left, with Crabbe and Goyle forming an impromptu wall that blocked any retreat toward his bed. Even Blaise, typically the most aloof of the group, had abandoned his usual pretense of disinterest and moved closer.
"Right," Draco said without preamble, his grey eyes intense. "No more of this 'I fed her a rat' nonsense. We're your dormmates, Potter. We're supposed to be allies. So tell us what actually happened."
"I fed her a rat," Harry repeated calmly, moving past them toward his trunk. Sylvia, sensing the tension, raised her head from where she'd been resting against his collar.
Sylvia made a hiss, and all his friends flinched hard and looked like they were ready to run.
"Easy," Harry murmured, stroking her head with one finger. She settled immediately, though her dark eyes remained fixed on Draco. "They're just curious. They don't mean any harm."
"That thing," Draco said, his voice pitched slightly higher than normal, "is going to sleep in here? With us?"
Harry glanced at him, amusement flickering across his features. "Sylvia's harmless. She won't bother you unless you bother her." He continued unpacking his school bag with one hand while keeping the other near Sylvia. "Besides, she'll probably spend most nights hunting. Snakes are nocturnal."
"Probably?" Crabbe echoed nervously, staring at the black-scaled serpent like it might suddenly launch itself at his throat.
"They do what they want," Harry said with a shrug. "I can't exactly order her to stay away. She's not a house-elf."
Goyle took a hesitant step forward, his large hands clenched at his sides. Unlike the others, he didn't look afraid, more fascinated than frightened. "Can I... could I touch her?"
The request surprised everyone, particularly Draco, whose expression suggested his friend had just volunteered for a Crucio demonstration.
Harry considered for a moment, then nodded. "Slowly. Let her see your hand first, then touch near her head. She's not aggressive, but sudden movements make any animal nervous."
Goyle approached with surprising caution for someone his size, extending one massive hand palm-up. Sylvia's tongue flicked out, tasting the air near his fingers. Then, apparently satisfied, she allowed him to run one finger along her scales.
"She's smooth," Goyle said wonderingly. "Thought snakes would be slimy."
"Common misconception," Harry replied. "Scales are dry. Smooth, but dry."
Theodore watched this interaction with narrowed eyes, his analytical mind clearly working. After Goyle stepped back—looking absurdly pleased with himself—Theodore spoke up.
"That's complete rubbish, you know. The feeding story."
Harry paused in the act of pulling out his pajamas. "Is it?"
"Yes," Theodore said flatly. "I don't know what actually happened, and I'm not going to waste time guessing. But snakes don't switch allegiances based on a single meal, Mulciber doesn't back down from public challenges, and you're entirely too calm about having somehow acquired his primary means of intimidation." He crossed his arms. "So yes. Rubbish."
The dormitory fell silent. Harry met Theodore's gaze steadily, neither confirming nor denying. After a long moment, he smiled slightly.
"You're absolutely right that it's your choice whether to believe me or not."
"That's not an answer," Theodore pointed out.
"No," Harry agreed pleasantly. "It's not."
Draco made a frustrated sound. "For Merlin's sake, Potter, we're on your side! We're not going to run to Snape or spread stories. We just want to know what actually happened!"
"Do you?" Harry asked, turning to face them properly. "Because I think what you actually want is to understand how I did it. To know what tools or knowledge or advantages I used so you can... what? Replicate them? Use them yourself? Judge whether I'm dangerous?"
The accuracy of this statement clearly hit home. Draco's face flushed, and even Blaise looked slightly uncomfortable.
"We're just curious," Crabbe offered weakly.
"Curiosity is fine," Harry said, softer now. "And I don't blame any of you for wanting answers. But some things work better when they're not explained in detail." He gestured at Sylvia. "The important facts are these: Mulciber threatened us. Now Mulciber leaves us alone. The snake that was his tool is now my companion. That's really all you need to know."
"Unless Mulciber decides he wants revenge," Draco argued. "Then we might need to know exactly what we're defending against."
"If Mulciber wanted revenge," Harry said logically, "he wouldn't have walked past me without a word tonight. Whatever happened, it's finished. He knows it. I know it. And now everyone else knows it too."
Blaise had been quiet throughout this exchange, but now he stepped forward with that calculating look he got when pieces were falling into place in his mind. "You're protecting him."
"What?" Draco turned to stare at him.
"Potter's protecting Mulciber," Blaise repeated. "By not explaining exactly what happened, by maintaining this simple story that everyone can see through but nobody can disprove. He's giving Mulciber an out. A way to save face without having the specific details of his humiliation spread throughout the school."
Harry said nothing, but something in his expression suggested Blaise had hit closer to the truth than expected.
"Why?" Draco demanded. "Why protect someone who threatened you?"
"Because," Theodore said slowly, understanding dawning in his grey eyes, "a beaten enemy who's been shown mercy is less dangerous than one who's been completely destroyed. If Potter had exposed whatever really happened—had made Mulciber look like an even bigger fool in front of everyone—Mulciber would have nothing left to lose. He'd have to retaliate just to salvage some dignity."
"But this way," Blaise continued, warming to the theory, "Mulciber can tell himself and others that he simply chose to give up a pet that had become unreliable. It's a loss, but not a complete humiliation. And in exchange for that small mercy, he stays quiet about whatever actually happened."
Harry's smile widened fractionally. "You're all very clever.."
"So we're right?" Draco pressed.
"I'm saying," Harry said carefully, beginning to unbutton his robes, "that sometimes the best victory is one where your opponent is grateful you didn't win more decisively. And now, if you're all quite finished interrogating me, I'd like to change for bed."
Goyle, still looking pleased about being allowed to touch the snake, nodded and moved toward his own trunk. Crabbe followed automatically, as he usually did. Blaise simply smiled his knowing smile and turned away, apparently satisfied with the non-answer he'd received.
Theodore held Harry's gaze for a moment longer, then nodded slowly. "Fair enough. But Potter? When you decide you need allies for whatever you're actually planning—and don't pretend you're not planning something—remember we're already on your side."
"Noted," Harry said. "And thank you. All of you."
Draco lingered even as the others dispersed to their own preparations for bed. His voice, when he finally spoke, was quieter than usual. "My father always says that making enemies is easy. Making the right kind of allies—the ones who'll support you when it matters—that's the real challenge."
"Your father sounds wise," Harry replied.
"He is." Draco hesitated. "The snake really won't... I mean, it stays with you, right? It's not going to wander around at night?"
Harry's expression softened. "She'll probably go hunting, like I said. But she won't bother anyone in the dormitory. You have my word."
"Good." Draco straightened, some of his usual hauteur returning. "Because if I wake up with that thing on my pillow, alliance or not, I'm hexing it."
"Noted," Harry said with a grin.
As the dormitory settled into its nighttime routine—robes exchanged for pajamas, teeth brushed, curtains adjusted around beds—a strange sense of camaraderie filled the room. They were allies now.
Goyle paused by Harry's bed on his way to his own. "Thanks," he said quietly. "For standing up to Mulciber. For all of us."
"We stand up for each other," Harry replied simply. "That's what being in the same house means."
"Not for everyone," Goyle said, glancing at where Mulciber's dormitory would be, several floors above them. "But yeah. For us."
Theodore was the last to settle into bed, and Harry caught him watching from between his curtains with that thoughtful expression he wore when puzzling through complex problems.
"Something on your mind?" Harry asked quietly.
"Just thinking about chess," Theodore replied. "How the best players don't just plan their own moves, but anticipate their opponent's responses three, four, five moves ahead. Control the board without seeming to."
"Do you play?"
"I do. Not as well as I'd like, but I'm learning." Theodore's eyes glinted in the dim light. "Maybe you could give me some pointers sometime. Sounds like you might have some interesting strategies."
"Maybe I could," Harry agreed.
As lights were extinguished and the dormitory fell into darkness, Harry lay awake for a while, Sylvia coiled contentedly on the pillow beside him. Around him, his dormmates breathed in the various rhythms of approaching sleep.
They didn't know the whole truth. They probably never would. But they'd accepted him anyway, had chosen to stand with him despite—or perhaps because of—the mystery.
That was worth more than any amount of explanation.
Sylvia's scales rustled softly as she adjusted her position. "Smart hatchlings," she murmured in Parseltongue, too quiet for sleeping boys to hear. "They sense you are dangerous, but choose to be your allies rather than your enemies."
"They're not hatchlings," Harry whispered back in the same language. "They're my age."
"To me, all two-legs are hatchlings," Sylvia replied with what might have been amusement. "But these are cleverer than most. You chose your den-mates well, speaker."
"I didn't choose them. The Sorting Hat did."
"Did it? Or did it see what you needed and gave you what would serve you best?"
Harry had no answer for that, so he simply closed his eyes and let sleep claim him, still smiling slightly at the philosophical musings of a snake who'd known him less than a day but seemed to understand him better than most humans ever had.

Sleep wouldn't come.
Harry lay in his bed, curtains drawn, listening to the rhythmic breathing of his dormmates. Draco snored softly—he'd deny it vehemently if confronted, but the sound was unmistakable. Crabbe's breathing was heavy and regular, while Goyle occasionally mumbled something incomprehensible. Theodore and Blaise were silent sleepers, but Harry could tell from the stillness that they'd both drifted off.
Only he remained awake, mind too active to settle despite the late hour.
The dormitory's enchanted window showed the lake in its nighttime state—darker, more mysterious, with occasional flashes of bioluminescent creatures passing by. Harry watched a school of silver fish dart past, then made his decision.
He slipped from bed with silence, the kind learned from years of sneaking to the Dursleys' kitchen for food. His bare feet made no sound on the stone floor as he dressed quickly in dark clothes. Sylvia, who'd been coiled on his pillow, raised her head questioningly.
"Want to explore?" Harry whispered in Parseltongue.
"Always, speaker," she replied, slithering down to wind herself around his shoulders beneath his cloak. "The castle at night calls to serpents."
Harry moved to the dormitory door, easing it open. The common room beyond was empty, lit only by the dying embers in the fireplace and the eerie green glow from the lake windows. He crossed it quickly and spoke the password to the exit.
The corridor beyond was dark—properly dark, the kind of darkness that would send most eleven-year-olds running back to bed. But Harry had grown up in a cupboard under the stairs, where darkness was a constant companion. He'd spent countless nights navigating the Dursley house in complete blackness, stealing food or simply escaping the cramped space that passed for his room.
Darkness didn't frighten him. In some ways, it was almost comforting.
His hand moved toward his wand, and he almost cast Lumos before stopping himself. No. Light would attract attention, and his eyes would adjust. They always did.
"Can you sense the way ahead?" he asked Sylvia quietly.
"Yes, speaker. There are many two-leg paintings on these walls. Metal two-legs that don't move. Stone that shifts and stone that stays." Her tongue flicked out, tasting the air. "I will tell you before you walk into obstacles."
They moved through the castle like shadows, Harry's eyes gradually adjusting to the ambient light from windows and the occasional torch that hadn't quite burned out. Sylvia was true to her word, giving quiet warnings in Parseltongue whenever they approached a suit of armor or a portrait that might rouse and ask questions.
"Left here," she hissed softly. "There is an open space ahead, but the floor becomes stairs. Be careful."
Harry felt along the wall, found where it curved, and discovered she was right—a narrow staircase led upward. He climbed carefully, one hand on the wall for guidance.
The castle was different at night. During the day it bustled with students and teachers, filled with noise and movement and life. But now, in these small hours, it felt ancient. Patient. Like something that had stood for a thousand years and would stand for a thousand more, indifferent to the brief lives that passed through its halls.
Harry found himself on the third floor, not the forbidden corridor, he was careful about that. He ran his hand along the stone walls, feeling for anything unusual. Gaps, hidden alcoves, anything that might indicate a secret.
Nothing.
He tried several corridors, checking every suspicious section of wall, every tapestry that might hide a passage. But aside from normal castle architecture, he found nothing remarkable.
"This is frustrating," he muttered, more to himself than Sylvia. "There has to be something here. Castles this old always have secrets—hidden rooms, priest holes, escape tunnels. But I'm missing something."
"Perhaps you need different eyes," Sylvia suggested. "Or perhaps a spell? Two-legs have magic for revealing hidden things, yes?"
"Probably," Harry admitted. "But I don't know them yet. First-year curriculum doesn't exactly cover detecting secret passages."
He was about to suggest they return to the dormitory when a voice spoke from the darkness behind him.
"What are you doing out here, little snake?"
Harry spun, wand rising instinctively. But he lowered it almost immediately when he saw who—or rather, what—had spoken.
The Bloody Baron floated in the corridor, his gaunt face and hollow eyes somehow even more disturbing in the darkness. His robes were stained with silver bloodstains, and the chains he wore clinked softly despite being insubstantial.
Harry shot Sylvia a reproachful look. "You didn't sense him?"
"Don't blame her," the Baron said, drifting closer. His voice was surprisingly gentle for someone so terrifying in appearance. "I'm a ghost. No scent for serpents to detect. No warmth, no breath, no physical presence. Snakes cannot see ghosts—we exist on a different plane from living creatures."
Harry blinked. "Really? I didn't know that."
"Why would you?" The Baron tilted his head, chains rattling. "Not the sort of thing they teach in your classes. I never thought to ask why, myself. Some things simply are, without explanation."
There was a pause as they regarded each other, living boy and dead man, separated by centuries yet standing in the same corridor.
"You asked what I'm doing," Harry said finally, deciding honesty was probably safer than lying to a ghost who could float through walls. "I'm exploring. A castle this old, this large... it must have secrets. Things hidden. I wanted to find them."
The Baron's expression shifted to something that might have been approval. "Most children your age prefer their beds at this hour. Sleep, dreams, the comfort of routine. But not you."
"I've never been particularly fond of routine," Harry replied. "Besides, I spent enough time in the dark growing up that it doesn't bother me. Actually prefer it sometimes—everything's quieter, simpler. You can think without interruption."
"A philosopher as well as an explorer," the Baron mused. "How refreshing. The castle does hold many secrets, young snake. Especially for curious boys willing to look for them."
Harry leaned forward slightly. "Are there any in particular I should know about?"
The Baron's laugh was like wind through broken windows. "The best hidden places are those you find yourself. Discovery means more when you've worked for it, earned it. But I'll offer you this—curiosity is admirable, but it must be tempered with caution."
"Meaning?"
"Meaning that forbidden corridor on this floor." The Baron's expression darkened, becoming truly frightening. "Do not go there. That's not a mystery to solve—that's genuine danger. The Headmaster's warning wasn't empty dramatics. Students could die, and I have no wish to welcome more ghosts to this castle."
"Understood. I'll stay away."
"Good." The Baron seemed to relax slightly. "There are other places worth your attention. Less lethal, more rewarding. The Viaduct Bridge, for instance. Observant students often find it... enlightening."
"The Viaduct Bridge," Harry repeated, committing it to memory. "I can't go tonight—I'd never find my way there in the dark—but thank you. I'll investigate when I can."
"See that you do. And little snake?" The Baron paused. "Be careful in your explorations. The castle protects those it favors, but even it has limits. Some secrets are buried for good reason."
"I'll remember," Harry promised.
The Baron nodded once, then began to drift away, passing through a tapestry as though it were mist. His chains' soft clinking faded into silence, leaving Harry alone again in the dark corridor.
Well, not entirely alone.
They'd barely gone twenty paces when another voice spoke, female this time, softer than the Baron's but carrying easily in the empty corridor.
"Be careful of the Bloody Baron."
Harry whirled around, wand rising again. "Who's there?"
The corridor stretched empty behind him. No ghosts, no students, no portraits awake to witness his confusion. Just stone and shadow and silence.
"Hello?" he called quietly, not wanting to wake anyone but hoping for a response. "I can hear you. You can show yourself—I won't cause any trouble."
Still nothing.
Harry waited a full minute, but the mysterious voice didn't return. Finally, he shook his head and continued walking.
"Did you hear that?" he asked Sylvia.
"No, speaker. Two-legs make sounds serpents cannot always hear. Your voices carry differently than ours."
Another ghost, Harry reasoned. Had to be. But why warn him about the Baron? The Bloody Baron had seemed helpful, even protective in his way. Unless there was some danger Harry hadn't recognized?
Or maybe it was just a ghost with outdated information, warning him away from someone they didn't trust. Ghosts were frozen in time, after all—their knowledge and prejudices locked in the moment of their death. Perhaps this mysterious female ghost remembered a different Baron, one from decades or centuries ago.
Too many questions, not enough answers.
The journey back to Slytherin's common room was uneventful, and Harry found himself grateful for Sylvia's guidance through the darker sections. By the time he whispered the password and slipped inside, his eyes were starting to feel heavy.
The dormitory was exactly as he'd left it—his roommates still asleep, completely unaware of his midnight excursion. Harry changed back into his pajamas and slipped into bed, Sylvia coiling beside him once more.
"Interesting night, speaker," she murmured sleepily.
"Very," Harry agreed. "Though I'm not sure what we actually learned."
"That the castle has secrets. That dead two-legs walk its halls. That some places are dangerous even for clever speakers." She settled more comfortably. "And that you are patient enough to search for answers rather than demanding them. That may be the most important lesson."
Harry smiled at that. "You're very wise for a snake."
"All serpents are wise. Most two-legs simply don't listen."
As sleep finally claimed him, Harry's mind replayed the night's encounters. The Bloody Baron's warning about the third-floor corridor. His suggestion about the Viaduct Bridge. The mysterious female voice urging caution.
Tomorrow he'd begin planning his exploration of the Viaduct Bridge. Tonight, he'd earned his rest.
Dumbledore and Snape
One week later, Severus Snape stood in his office grinding pearls for a particularly delicate potion, trying to ignore the summons he'd received from the Headmaster. Trying and failing, because ignoring Dumbledore was rather like ignoring a hurricane, technically possible, but ultimately futile and bound to result in disaster.
With a sigh that would have done a martyred saint proud, he vanished the pearl dust, cleaned his workspace with three efficient spells, and swept from his office in a billow of black robes.
The gargoyle guarding the Headmaster's office leaped aside at his approach—he was expected, obviously—and Snape climbed the spiral staircase with all the enthusiasm of a man approaching his own execution.
"Ah, Severus," Dumbledore greeted him cheerfully as he entered. The Headmaster sat behind his desk, surrounded by the usual collection of delicate silver instruments, snoozing portraits, and Fawkes preening on his perch. "Thank you for coming. Lemon drop?"
"No." Snape remained standing despite the offered chair. "What is it you need, Headmaster? I have a batch of Pepperup Potion that requires attention."
"This won't take long," Dumbledore assured him, his blue eyes twinkling in that maddening way that suggested he knew far more than he was saying. "I simply wanted to touch base about our young Mr. Potter. He seems to be settling into Slytherin House remarkably well."
Snape's jaw tightened. "If by 'remarkably well' you mean he's managed to acquire Mulciber's snake and parade it around the castle like some kind of trophy, then yes. Settling in splendidly."
"You disapprove of his having a pet?"
"I disapprove," Snape said through gritted teeth, "of a first-year somehow convincing a fourth-year's familiar to transfer its loyalty. The creature follows him everywhere. Draped across his shoulders like—like—"
He stopped, unable to articulate exactly what bothered him about the image without revealing more of his emotional state than was wise.
"Like he belongs in Slytherin?" Dumbledore suggested mildly.
Snape's eyes flashed. "Do you know why Potter has that snake, Albus? Do you know what happened between him and Mulciber?"
"I know that Harrison Mulciber has filed no complaints, broken no rules, and appears to have accepted the situation with remarkable grace," Dumbledore replied, leaning back in his chair. "Beyond that, I confess I haven't inquired. Have you?"
"I have no reason to interrogate students about their pets," Snape snapped, though his tone suggested he found the entire situation deeply suspicious. "Unless you'd like me to begin including pet ownership disputes in my duties as Head of House?"
"I think not. Though I notice you're concerned about this particular situation."
"Because it's impossible!" Snape exploded, his careful composure cracking. "Snakes don't simply change allegiance. Mulciber has owned that creature since his second year—three years of building familiarity and routine. Yet somehow Potter walks away with it after less than two weeks at this school? That's not natural animal behavior, Albus. That's something else entirely."
Dumbledore regarded him thoughtfully over his half-moon spectacles. "And you suspect... what, precisely?"
Snape hesitated, clearly unwilling to voice his suspicions without evidence. "I suspect," he said finally, "that Potter is more than he appears. That he's using methods or abilities we're unaware of. That he's—"
"Dangerous?" Dumbledore supplied.
"I didn't say that."
"But you thought it." The Headmaster's expression remained serene. "Severus, Harry has behaved appropriately in all his classes. He has earned more points for the Slytherins than his year, second year and third year combined, his conduct acceptable, his interactions with other students reasonably cordial. I see no cause for concern."
"Then you're not looking closely enough!" Snape's hands clenched at his sides. "Headmaster, I believe we should reconsider his house placement. Move him to Gryffindor where he belongs, where his father's legacy—"
"No." Dumbledore's voice rose for the first time.
"But—"
"Severus, we have discussed this." Dumbledore's voice was gentle still, but Snape knew this was his warning voice, and he felt a shudder in his body. "I will not change Harry's house simply because he was sorted into Slytherin. The Sorting Hat's decisions are not subject to administrative override based on faculty preference or personal bias."
Snape's face contorted with suppressed fury. "The boy dares to have her—" He stopped abruptly, unable or unwilling to finish the sentence.
"Her eyes?" Dumbledore suggested quietly. "Her hair? Her quick mind? Yes, Severus. Lily was his mother. Of course, he would take after her in many ways. Children tend to take after their parents, were you not aware of that?"
"Do not mock me," Snape said with a glare, but Dumbledore didn't seem bothered by it. "The boy may look like her," Snape said, his voice dropping to a dangerous whisper, "but he acts like his father. The arrogance, the assumption that rules don't apply, the way he manipulates situations to his advantage while maintaining that facade of innocence. If not worse than James."
"Or," Dumbledore countered, his tone sharpening slightly, "he has survived a childhood of neglect with his intellect intact. That's resourcefulness, Severus. Adaptability. The very qualities Slytherin House values. Perhaps you're seeing what you expect to see rather than what's actually there."
Snape stood abruptly, his chair scraping harshly against the floor. "You don't understand."
"I understand grief," Dumbledore said, his voice heavy with the weight of his own losses. "And I understand holding grudges. I've done both, to my lasting regret. But this boy is not his father, Severus. He's had a different life, faced different challenges. He deserves to be judged on his own merits, not punished for resembling a man who's been dead for ten years."
"He has his father's disregard for consequences," Snape insisted. "His expectation that he can do as he pleases without facing punishment. Already he's established some kind of dominance over older students, acquired property that isn't rightfully his, and walks around as though he owns the dungeons. Tell me that's not James Potter's arrogance!"
"I tell you," Dumbledore replied steadily, "that it might also be a boy who learned to survive in an environment where showing weakness meant suffering. A boy who's learned to read people, to position himself advantageously, to protect himself and those he cares about. Those are survival skills, Severus. Not moral failings."
"You see what you wish to see, Headmaster," Snape said coldly.
He turned toward the door, robes billowing dramatically with the movement.
"As do you, my boy," Dumbledore called after him. "As do you."
Snape didn't respond, simply swept from the office and down the spiral staircase, his footsteps echoing his anger. The gargoyle jumped hastily aside as he passed, wisely choosing not to impede a Potions Master in such a mood.
Dumbledore sat alone in his office, the cheerful facade dropping away to reveal genuine concern. He popped a lemon drop into his mouth absently, gazing at the various silver instruments whirring and spinning on their delicate stands.
One in particular, a device that measured magical disturbances within the castle, had been showing unusual readings near the Slytherin dormitories. Nothing dangerous, but... irregular. The kind of irregularity that suggested someone was doing magic slightly beyond their expected capability.
Or perhaps using magic in unexpected ways.
"Harry Potter, quite an interesting child. I'm curious to see where the road will lead you,"
