She had expected them to disperse. They did not. Instead, like a pack of circling predators, a group of older boys joined Malfoy, Crabbe, and Goyle, along with some senior year girls forming a loose, intimidating semi-circle that cut off her path to the dormitories. The other first-year girls, seeing their chance to escape the tense atmosphere, scurried away towards their dormitory, leaving Hermione alone with the boys.
"Well, well," Malfoy began, his earlier bravado returning now that he had a wall of older students behind him. His voice took on that practiced, mocking drawl. "Look what the Hat dragged in. A filthy little Mudblood, all alone."
A ripple of cruel laughter went through the circle surrounding her.
Hermione looked him straight in the eye, an expression of pure boredom. "Really, Malfoy? Is that the best you could do? Must have taken all three of your braincells a whole day to come up with that."
The laughter died instantly. A heavily built sixth-year stepped forward, his jaw tight. "Watch your mouth, you little bitch. You are not better than us, you filthy Mudblood."
Hermione laughed at that, derisively. "Ah, that's where you are wrong, you idiot. I am better than you. Not having a pretzel like family tree already makes me a lot better than you lot. Seriously, how many of your parents are first cousins? Because it really explains the collective brain damage in this room."
The sixth-year turned a violent shade of purple, taking a threatening step forward. Malfoy, desperate to keep the spotlight, shoved his way back to the front. "My father says your kind are animals," he spat, spittle flying from his lips. "Pretending to be people. You ought to be put on a leash."
Hermione mimed her hands, mocking him, disgust and amusement on her face evident about what she thought about his father. "'My father this, my father that'. Are you physically capable of an original thought, Malfoy, or is your father's hand just permanently shoved so far up your arse, working your mouth like a puppet? Do you need him to tell you how to wipe your own shit, too?"
The silence that followed was suffocating. Malfoy's face went stark white, then flushed a furious, ugly red. He was physically shaking, his mouth opening and closing without sound.
Another senior student, lounging against a stone pillar with his arms crossed, scoffed loudly to break the tension. He pushed off the stone, his wand slipping into his hand with a practiced flick. "All bark," he sneered, pointing the tip loosely at her chest. "How about I hit you with a Stinging Hex right now? Give you some nice, weeping boils to match your filthy blood. Let's see how much you talk when your face is swollen shut."
The threat hung in the air, a direct escalation. They smirked, expecting her to shrink back, to prove she was the helpless fraud they wanted her to be.
Hermione looked at the wand, then up at the boy's face.
"A Stinging Hex?" she asked, her voice dropping into a dangerous, deadpan quiet. "That's the best you can do? Well then, I believe its going to be short fight before I put you in the hospital wing drinking your meals through a straw for weeks. Don't beg for things you can't survive."
An older, imposing seventh-year student with a cruel face stepped forward, clearly the leader of the group, his patience finally snapping. Her complete and utter dismissal of their magic was a far greater insult than anything she had said about their heritage. "Clever mouth for a filthy Mudblood," he snarled, his wand now in his hand. "Let's see if you're still so clever after a curse."
He raised his wand, the tip glowing with a faint, ugly purple light.
Hermione's expression did not change, but her eyes went cold, losing any hint of the child she had been pretending to be. "I see," she said, her voice dropping into a quiet, almost contemplative tone. "You've chosen the educational path."
And the room changed.
The first thing to go was the warmth. The grand, crackling fire in the hearth didn't just go out; it was smothered, the flames sputtering from a cheerful orange to a sickly blue before dying completely, leaving only a pile of silently glowing embers. A profound, unnatural cold radiated from her in a silent, creeping wave. The temperature in the common room plummeted so sharply that students gasped, their breath misting in the air. The chill wasn't just physical; it was a deep, primal cold that felt wrong, alien, and sank straight into the bone.
The seventh-year's bravado faltered, the spell on his lips dying as he felt the impossible chill. Before he could even process the change, he suddenly choked, his eyes widening in pure, animalistic terror. His hands flew to his throat, clawing at an invisible force that had completely cut off his air. A horrifying, rasping sound was the only thing that escaped his lips as his face began to turn a dusky, mottled purple. He stumbled back, his wand clattering uselessly to the stone floor.
It wasn't just him. The other students in the circle felt it too. A heavy, crushing pressure descended on the room, like the weight of the lake above was pressing in on them. Knees buckled. Two of the older girls stumbled and fell to the floor, gasping. Malfoy, his arrogant sneer completely gone, was pale and on his hands and knees, the front of his robes rapidly darkening with a stain, his cronies looking desperately for a way to escape the invisible weight.
With the entire room held in her silent, terrifying grip, Hermione finally spoke. Her voice was quiet, almost a whisper, yet it carried to every corner of the frozen common room with absolute, chilling clarity.
"I am to be left alone. This… is your only warning."
The effect vanished as quickly as it had begun. The fire roared back to life with a loud whoosh, bathing the room in warmth again. The pressure disappeared. The seventh-year collapsed to the floor, sucking in a shuddering, desperate breath, his face a mask of pure terror. The others scrambled back, their bravado shattered, their eyes fixed on the small, eleven-year-old girl who hadn't moved a muscle.
No one saw a spell. There was no proof. There was only the memory of that impossible cold and the quiet girl who was its undeniable source.
Hermione turned and walked towards the girls' dormitories without a word.
The door to the girls' dormitory was a heavy slab of dark, polished wood set into the stone. It swung open silently at her touch, revealing a circular room beyond. Five four-poster beds, each hung with emerald green silk curtains embroidered with silver thread, were arranged around the room. Her trunk was already at the foot of one. The air was cool and smelled faintly of lavender and old stone.
The other girls were already there. Tracey Davis and another girl with blonde hair, Lily Moon, were quietly unpacking on the far side of the room, talking among themselves. Daphne Greengrass was already sitting on the bed next to Hermione's designated spot, watching the door with a calm, assessing gaze.
But it was Pansy Parkinson and Millicent Bulstrode who stood near the center of the room, their expressions curdling into familiar, sneering arrogance. Having missed the confrontation in the common room, they saw only the target they had been waiting for. As Hermione moved towards her bed, they shifted, deliberately blocking her path.
"The Hat might have made a mistake, but we won't," Pansy sneered, her hand on her wand. "You don't belong here, Mudblood."
Hermione sighed, "This again." She didn't even glance at Pansy's wand. She looked directly at her mouth. "That is not a word you will ever use again in my presence."
Pansy opened her mouth to deliver a scathing retort, but no sound came out. Her eyes widened in confusion. Then, the true terror began. She felt the sensation of her mouth completely vanishing, the skin smoothing over in a seamless, horrifying blankness. A choked, panicked squeal was trapped in her throat. Her hands flew to her face, feeling the unnatural smoothness where her mouth should be.
Millicent was frozen, her face white with shock. Daphne Greengrass sat up straighter, her face a poor attempt at maintaing composure as panic and fear bled through.
The silence that followed was thick and absolute, broken only by Pansy's muffled, terrified squeals. A soft sound cut through the tension. Her grey kitten, who had been napping at her bed, hopped down from her four-poster bed. He trotted across the stone floor, tail held high, utterly indifferent to the whimpering girl in the corner or the frozen statues of the others. He wound himself around Hermione's ankles, letting out a small, questioning meow.
Hermione bent down in one smooth, unhurried motion and scooped him into her arms. The kitten settled instantly, tucking his head under her chin and beginning to purr. She glanced over at the still-squealing Pansy, her expression one of mild annoyance. With a casual, dismissive wave of her free hand, the squealing noises abruptly stopped, though Pansy's mouth remained gone, her panic now utterly silent.
"That's better," Hermione murmured, more to the cat than anyone else. "The noise was getting tiresome." The cat seemingly meowed in agreement.
Cradling the cat, Hermione's gaze moved slowly, deliberately, from the frozen Millicent to the watchful Daphne, and then to the other two girls in the room, Tracey Davis and Lily Moon, who were huddled by their beds, eyes wide with fear, flinching as her gaze swept over them. Only then did Hermione speak, her voice quiet, cold, and carrying to every corner of the room while her fingers stroked the soft grey fur.
"Let's establish the rules for our cohabitation, shall we? So there is no confusion in the future."
She paused, letting the words hang in the suffocating silence.
"Rule one. I don't care about your delusions of your pure-blood shit. But you will not interfere with me, you will not touch my belongings, and you will not harm my pet." She gave the purring kitten a gentle scratch under the chin, the simple, affectionate gesture a chilling counterpoint to her words. "And you will not call me that word, ever again. Is that understood?"
A series of frantic, jerky nods were her only answer. Millicent looked like she might be sick.
"Rule two," she continued, her voice even calmer, which was somehow more menacing. "What just happened here... did not happen. Slytherin business is, I believe, meant to stay within Slytherin. If I hear a single whisper of this outside these walls, I will know it came from here. And the consequences," she paused, and a small, chillingly smile touched her lips, a smile that did not reach her eyes, "will be educational."
She gave them one last look, and flicked her hands towards the still curled Pansy on the floor. Pansy's mouth reappeared with a wet, gasping sound as she sucked in a shuddering breath, collapsing into a heap of terrified sobs.
She turned her back on them then, an act of such complete and utter dismissal that it was more terrifying than any threat. Placing the cat on her shoulder, she walked to her bed and calmly began to unpack her trunk, the soft rustle of her robes the only sound in a room of frozen, terrified girls.
Later, as she lay in her bed, the green silk curtains drawn, the only sounds were the soft, hypnotic lapping of the lake water against the thick glass of the window and the quiet, contented purr of her grey cat.
A part of her, the ghost of the boy on the train, felt a profound sense of dissonance. The casual cruelty, the calculated intimidation – they were actions so alien to his nature, that she felt such dissonance at what she had done, what had happened.
She knew there would be consequences. The story of the common room incident, of multiple students being incapacitated, would undoubtedly reach her Head of House, and from there, almost certainly the Headmaster. It would bring unwanted attention, new problems to solve.
A part of her was already running through the scenarios, preparing deflections and crafting plausible denials. But another, smaller part felt a strange, thrilling surge. Let them come. She recognized the feeling with a chilling clarity. It was the high of power, the quiet, seductive whisper that told her she was strong enough not to care about the consequences. It was the first taste of what corruption might feel like, and immediately tried to rein it in.
And yet, the results were undeniable: silence, fear, and a wide, respectful berth. This was the language her new world understood. This was survival. And as the last vestiges of the day's tension bled away, she acknowledged a deeper, more profound truth.
In the cold, quiet dark of the serpent's den, surrounded by predators she had already tamed, for the first time, this strange new skin felt completely and utterly like home.
