It snowed on Saturday.
Not the polite, decorative kind of snow that settled on windowsills and made everything look like a greeting card. The proper Scottish kind — horizontal, committed, with wind that had come a long way and had opinions about it.
Mia stood at the castle doors and looked at it.
"We don't have to go," Bellatrix said, appearing beside her in a long dark coat that somehow made her look like she'd been planning to conquer something.
"We've been inside for three weeks."
"We went to Little Hangleton."
"That doesn't count as a day out." Mia pulled her own coat tighter. "Come on."
Hogsmeade in a snowstorm was quieter than usual, which suited them. Most students had looked out of a window and made sensible decisions. The streets were half empty, the shop windows warm and lit against the grey, and they walked without particular destination in the kind of comfortable silence that had become, over months, one of Mia's favourite things.
Bellatrix had her hands in her pockets. She was looking at the street with the alert, taking-everything-in expression she wore when she wasn't performing anything for anyone — not the composed public face, not the focused working face, just her, paying attention to the world.
"You're doing it again," Mia said.
"Doing what."
"Looking at things like you're memorising them."
Bellatrix glanced at her sideways. "I always look at things like that."
"I know. I like it." She paused. "You see things other people miss."
"Most people aren't looking properly." She stopped outside Tomes and Scrolls and looked at the window display with what was clearly involuntary interest — a new collection of advanced charms theory, just in. "We could—"
"Yes," Mia said.
"I didn't finish the sentence."
"You were going to ask if we could go in."
"I was going to suggest it as a possibility."
"Bellatrix."
"Fine. Yes."
They spent forty minutes in Tomes and Scrolls, which was forty minutes longer than most people spent in Tomes and Scrolls but about right for them.
Bellatrix moved through the shelves with the focused energy of someone doing something they genuinely loved, pulling volumes and reading the first chapter before deciding. She had opinions about everything — strong ones, delivered in the quiet decisive way she delivered most things, and Mia argued back when she disagreed and agreed when she didn't and the conversation ran through three subjects and never quite stopped.
At some point Mia realised they'd been standing in the same aisle for twenty minutes and she was no longer looking at books at all.
Bellatrix was reading the back of a volume on advanced rune theory, her brow slightly furrowed, lips moving fractionally with the text. She had snow still melting in her dark hair from outside. There was the faintest flush on her cheeks from the cold.
She looked up and caught Mia watching.
"What," she said.
"Nothing," Mia said. "I'm buying that for you."
Bellatrix looked at the book. "You don't have to—"
"I want to." Mia took it from her hands. "Consider it a thank you for the Little Hangleton counter-curses."
"That was a practical necessity."
"Still." She went to the counter before Bellatrix could argue further, which she absolutely would have, and paid for it and came back and handed it over.
Bellatrix looked at it in her hands for a moment with an expression Mia had never quite seen on her before — slightly off-balance, like she'd stepped expecting one stair and found two. Like she wasn't entirely sure what to do with being given something with no strings attached.
"Thank you," she said. Quiet and genuine.
"You're welcome," Mia said, just as simply.
They stood in the bookshop while the snow came down outside and Bellatrix tucked the book inside her coat with the careful deliberateness of someone putting something somewhere safe, and Mia thought she might actually burst with how much she loved her.
Not almost. Not getting there.
Completely.
She'd known it for a while. She just hadn't said it yet.
They went to the Three Broomsticks because Bellatrix said Madam Rosmerta made the best Butterbeer in Britain with the authority of someone who had conducted a thorough survey, and Mia had no grounds to dispute it.
It was warm inside and loud with the students who'd braved the weather, and they found a table in the back corner and sat with their drinks and let the noise of everyone else wash around them.
Bellatrix wrapped both hands around her mug. She was looking at the room with that same alert attention she'd given the street, cataloguing everything automatically.
"Avery's watching us," she said, without inflecting it as anything concerning.
Mia didn't look over. "Since we came in?"
"Since we sat down. He clocked the corner table and the fact that I didn't choose somewhere more central." She took a sip. "He's not unfriendly. He's recalibrating."
"Recalibrating what."
"What I am." She said it simply. "Most of my housemates have been doing it since September. I came back to school this year different and they're deciding what that means." She looked at Mia. "You're the visible change."
"Does that bother you."
"No." Immediate, definite. "They can recalibrate. What I care about doesn't require their understanding."
Mia looked at her across the table, the noise of the pub around them, snow against the windows. "What do you care about?"
Bellatrix met her eyes. "You know what I care about."
"I like hearing it."
"That's demanding."
"Slightly," Mia agreed.
Bellatrix looked at her for a moment with an expression that was fond and exasperated and underneath both of those, completely open. "This," she said. "You. The work. Winning." A pause. "Mostly you."
Mia felt something warm settle in her chest. "Mostly?"
"The work is very important."
"Naturally."
"Don't look smug."
"I'm not looking smug."
"You're absolutely looking smug." But the corner of Bellatrix's mouth was doing the thing it did, and she was looking at Mia with all the careful management entirely absent, just warmth and something fiercer underneath it that was always there, the particular quality of Bellatrix caring about something — completely and without reservation, nothing held back.
"I love you," Mia said.
She hadn't planned it. It came out the way true things come out when you stop managing them — simply, without ceremony, the most natural sentence in the world.
Bellatrix went very still.
Not the still of someone shutting down. The still of someone receiving something they'd been waiting for without knowing they were waiting for it. The still of a held breath.
"Mia," she said. Her voice was different — lower, the last layer of composure gone from it.
"You don't have to—"
"I love you," Bellatrix said. Said it like it had been sitting in her chest for months and she was only now letting it out. Like saying it was both the easiest and the most significant thing she'd ever done. "I have for — I don't know when it started. The summer, probably. Before I admitted it to myself."
"August," Mia said. "By the lake. When you didn't take your hand away."
Bellatrix looked at her. "You noticed that."
"I notice everything about you."
A pause. Then Bellatrix reached across the table and covered her hand with hers, right there in the Three Broomsticks with Avery watching from across the room and the snow coming down outside, and didn't take it away.
Not secret. Not managed.
Just real.
"Rodolphus is going to have a difficult year," Bellatrix said, after a moment.
Mia laughed — surprised and helpless. "That's what you're thinking about right now?"
"I'm thinking about several things simultaneously." But she was smiling, the full version, warm and completely unguarded. "I'm also thinking that I'm in Hogsmeade on a Saturday with the person I love and it's snowing and you bought me a book and this is—" She paused, looking for the word.
"Good," Mia said.
"Good," Bellatrix agreed. "Yes."
They sat with their hands together on the table while the afternoon went dark outside and the snow kept falling and the pub hummed around them, and it was, for a while, just that.
The walk back to the castle was silent, but the silence was full. The snow fell in thick, lazy flakes, catching in Bellatrix’s dark hair and on the shoulders of Mia’s cloak. Their hands stayed linked, even when the path grew narrow, even when they passed a group of huddled Hufflepuffs. The cold bit at Mia’s cheeks, but the warmth where their palms met was a steady, radiating counterpoint. It felt less like walking and more like crossing a threshold, leaving one world—the public, snow-blurred one of tentative declarations—for another, private one whose shape she could already feel in the accelerating beat of her own heart.
They didn’t speak in the Entrance Hall, or on the moving staircases. The castle was quiet, absorbed in its own Saturday stillness. Bellatrix’s grip on her hand was firm, purposeful, leading them unerringly toward the dungeons and the familiar, imposing door to her private room. She released Mia’s hand only to tap the lock with her wand, the mechanism clicking open with a soft, final sound.
The room was dim, lit only by the low fire in the grate and the grey afternoon light filtering through the high, narrow windows. It smelled of parchment, ink, and the particular, dark scent of Bellatrix’s magic—ozone and old books. Bellatrix shut the door behind them and leaned against it, her eyes finding Mia’s in the gloom.
“Here,” Bellatrix said, the word barely more than an exhale. It wasn’t a question. It was an affirmation.
Mia crossed the space between them. She didn’t hesitate. She brought her hands up, cold fingers brushing the melting snow from Bellatrix’s hair, then cupping her face. Bellatrix’s skin was chilled, but her eyes were fever-bright, watching Mia with that same open, unmanaged intensity from the pub. Mia kissed her.
It was different from every kiss that had come before. Not desperate, not frantic with relief or the aftermath of danger. This was slow. Deliberate. Mia poured everything she’d said in the Three Broomsticks into it—the love, the certainty, the future she was fighting for. Bellatrix made a soft, broken sound against her mouth and kissed her back with equal measure, her hands coming up to clutch at Mia’s robes, pulling her closer until not a sliver of air remained between them.
Bellatrix’s fingers worked at the fastenings of Mia’s winter cloak, her movements slightly clumsy with urgency. Mia helped, shrugging the heavy wool off her shoulders, letting it fall to the stone floor with a muffled thump. Bellatrix’s own cloak followed. Then her hands were under Mia’s jumper, palms skating up her ribs, and Mia gasped at the touch, at the heat of Bellatrix’s skin against her own.
“I love you,” Bellatrix whispered into the space between their mouths, the words a warm, damp confession against Mia’s lips. “I love you, I love you.” She said it like she was discovering it, like each repetition made it more true.
Mia kissed her again, deeper, her tongue sliding against Bellatrix’s. She walked her backward, away from the door, toward the large four-poster bed that dominated the room. Bellatrix went willingly, her own hands busy pushing Mia’s jumper up and over her head. The cool air of the room raised gooseflesh on Mia’s arms, but then Bellatrix’s hands were on her again, tracing the line of her spine, and she was burning.
They reached the edge of the bed. Bellatrix sat, pulling Mia down to stand between her knees. She looked up, her dark hair a wild frame around her face, her lips kiss-swollen and parted. Her hands settled on Mia’s hips, thumbs stroking the sharp bones there. “I want to see you,” Bellatrix said, her voice rough. “All of you.”
Mia nodded, her breath catching. She undid the button of her trousers, slid the zipper down. Bellatrix’s gaze was a physical weight, tracking every movement. Mia pushed the fabric over her hips, let it pool at her feet, stepped out of it. Then she was standing there in just her bra and knickers, the firelight painting her skin in gold and shadow.
Bellatrix’s eyes darkened. “Perfect,” she breathed, the word full of awe and possession. She leaned forward and pressed an open-mouthed kiss to Mia’s stomach, just above the waistband of her knickers. Mia shuddered, her fingers tangling in Bellatrix’s curls.
“Your turn,” Mia managed to say, her voice unsteady.
Bellatrix leaned back, a slow, wicked smile touching her lips. She pulled her own jumper off in one fluid motion, then reached behind her back to unclasp her bra. She let it fall away. Mia’s mouth went dry. Bellatrix was all elegant lines and fierce beauty, pale skin and dark, peaked nipples, the lean muscle of a duelist. Mia reached out, traced the curve of her breast with a reverent finger. Bellatrix’s breath hitched.
Then Bellatrix was standing, pushing Mia gently back until her knees hit the bed and she sat. Bellatrix followed her down, covering Mia’s body with her own, skin to skin. The weight of her, the heat, was overwhelming. Mia arched into it, her legs falling open to cradle Bellatrix between them. The rough silk of Bellatrix’s knickers brushed against the damp cotton of Mia’s own, and a sharp, sweet ache pulsed through her.
Bellatrix kissed her neck, her collarbone, the valley between her breasts. “I have wanted this,” she murmured against Mia’s skin, her breath hot. “Not just the sex. This. Knowing you’re mine. Knowing I’m yours.”
“You are,” Mia gasped as Bellatrix’s mouth closed over her nipple, tongue swirling. Pleasure shot straight to her core, liquid and urgent. “Bellatrix—”
Bellatrix moved lower, her kisses trailing down Mia’s stomach. She hooked her fingers in the lace of Mia’s knickers and drew them down, off, tossing them aside. The cool air touched Mia’s heated skin, followed immediately by the searing heat of Bellatrix’s gaze. She was exposed, completely, and the look on Bellatrix’s face—rapt, hungry, reverent—made her feel powerful instead of vulnerable.
Bellatrix settled between her thighs. She didn’t touch her, not yet. She just looked, her black eyes drinking in the sight. Mia felt herself flush, felt the wetness gathering, undeniable. “You’re so beautiful here,” Bellatrix whispered, her voice hushed. “All slick and ready for me.”
Then she leaned in and licked, one long, slow stripe from bottom to top.
Mia cried out, her back bowing off the bed. Bellatrix’s mouth was clever, relentless, exploring her with a focused intensity that stole all coherent thought. She licked and sucked, her tongue circling Mia’s clit before dipping inside her, tasting her deeply. Mia’s hands fisted in the sheets, her hips lifting, seeking more. Bellatrix gave it to her, one hand sliding under Mia’s arse to tilt her, to hold her right where she wanted her.
The orgasm built quickly, a tight, bright coil in her belly. “Bella, I’m— I’m going to—”
Bellatrix hummed against her, the vibration shooting through Mia like a live wire. “Come for me,” she commanded, her voice muffled against Mia’s skin. “Let me feel it.”
Mia shattered. Pleasure ripped through her, wave after wave, pulling a ragged, broken sob from her throat. Bellatrix stayed with her through all of it, gentling her touches until Mia was a trembling, boneless thing on the sheets, gasping for air.
Bellatrix crawled back up her body, kissing her way over Mia’s stomach, her ribs, between her breasts, finally claiming her mouth again. Mia could taste herself on Bellatrix’s lips, salty and intimate, and the possessiveness of it made something new clench low in her belly.
“My turn,” Mia whispered, her voice hoarse. She rolled them over, reversing their positions, Bellatrix’s dark hair fanning out across the pillow. Mia looked down at her—flushed, lips wet, eyes blazing with love and want—and felt her heart swell until it was almost painful.
She kissed her way down Bellatrix’s body, mapping the territory she already knew by heart but now claimed anew. When she reached the juncture of Bellatrix’s thighs, she found her as wet as Mia had been, her knickers soaked through. Mia peeled them off with careful hands. Bellatrix was watching her, her chest rising and falling rapidly.
Mia lowered her head. The first touch of her tongue made Bellatrix jerk, a sharp gasp tearing from her throat. Her taste was dark, addictive, utterly Bellatrix. Mia licked into her, learning her rhythm, finding the places that made Bellatrix’s thighs tremble and her breaths turn into sharp, pleading cries. Mia slid a finger inside her, then another, curling them just so.
“Mia— please—” Bellatrix’s hand tangled in her hair, not pushing, just holding on. “Right there, don’t stop—”
Mia didn’t stop. She worked her with her mouth and her fingers, until Bellatrix’s pleas dissolved into wordless sounds, until her whole body went taut and she came with a choked-off scream, her inner muscles fluttering tightly around Mia’s fingers.
Mia held her through it, gentling her until Bellatrix went limp, her grip on Mia’s hair softening to a caress. Mia crawled back up, gathering Bellatrix into her arms, pressing a soft kiss to her sweaty temple. Bellatrix turned her face into Mia’s neck, her breathing gradually slowing.
Outside, the snow continued to fall, blanketing the castle and the grounds in silent white. Inside, in the fire-warmed dark, they were tangled together, skin against skin, heartbeat against heartbeat. Bellatrix’s fingers traced idle patterns on Mia’s back.
“It is good,” Bellatrix murmured, her voice thick with satiation and sleep.
Mia smiled into her hair. “Yes,” she agreed, holding her closer. “It is.”
