You are an expert novelist with a gift for vivid, immersive prose. You write in tight third-person limited point of view with a strong narrative voice. Your prose is clean, precise, and engaging — you favor strong verbs, concrete details, and natural-sounding dialogue. You will be given a story bible (codex) containing canonical details about characters, locations, items, and lore. Use these details to ground your writing in the established world. Stay consistent with the codex. Write only the prose of the scene. Do not include titles, chapter headings, markdown formatting, or any commentary before or after the scene.

The Raven's Nest held the kind of darkness that made secrets
feel
lighter. Rory pushed through the door at half past nine, her delivery bag still slung across her shoulder, smelling of Szechuan pepper and fried rice. She'd meant to drop it upstairs first, but the October cold had seeped through her jacket during the last run, and the promise of Silas's whiskey pulled harder than the three flights to her flat. The green neon from outside painted the entrance in sickly light before the door swung shut behind her, sealing her into the amber warmth of the bar. Maps covered the walls like wallpaper—Prague, Berlin, Istanbul, cities she'd never seen but sometimes dreamed about when sleep came hard. Black-and-white photographs hung between them, faces frozen in Cold War certainty. Silas stood behind the bar, polishing a glass with
methodical
attention. His hazel eyes
flicked
up, registered her presence, and returned to his work. He didn't ask what she wanted. After eight months of living above his establishment, he knew she'd tell him when she was ready. She dropped onto a stool and let the bag slide from her shoulder to the floor. Her left wrist ached where the strap had dug in, right along the crescent scar. "Whiskey. The good stuff." "Rough night?" "Long night. There's a difference." Silas reached for the Redbreast without comment. The clink of glass against wood, the pour, the slide across the polished bar—a ritual as familiar now as breathing. Rory wrapped her fingers around the tumbler and let the heat of it settle into her palms. The door opened again. Cold air rushed in, carrying the smell of rain-slick pavement and exhaust. Rory didn't turn, not at first. The Nest attracted a steady stream of regulars, and she'd learned to recognize most by their
footsteps
, the particular rhythm of their arrival. These
footsteps
stopped. Hesitated. "Laila?" The name hit her like a fist to the sternum. Nobody called her that anymore. Nobody except— She turned
slowly
on the stool. Evan stood three feet inside the door, his hand still on the frame as if he might need to catch himself. He looked different. Thinner. The rugby player's build she remembered had whittled down to something more angular, harder. His dark hair had receded at the temples, and new lines bracketed his mouth. He wore an expensive coat, charcoal wool with the collar turned up, but it hung on him wrong, like he'd bought it for someone else's body. "Christ," he said. "It
really
is you." Her throat had closed. She took a deliberate sip of whiskey, let it burn a path down, forced her voice steady. "Rory." "What?" "I go by Rory now. Have for years." Something moved behind his eyes—confusion, maybe hurt. He'd always hated when she corrected him. "Right. Rory. I didn't know you were in London." "I am." She set the glass down
carefully
,
precisely
centered on the coaster. Her hands wanted to shake. She didn't let them. Evan took a step closer, then
seemed to
think better of it. His gaze swept the bar—the maps, the photographs, the empty tables scattered like islands across the scuffed floor. "This is... not where I'd picture you." "Where would you picture me?" The question came out sharper than she'd intended. "I don't know. Cardiff, I suppose. Your parents' house. Or some law firm, wearing one of those blazers you always hated." He attempted a smile. It didn't reach his eyes. "You finished the degree, didn't you? Passed the bar?" "No." The syllable hung between them, dense and immovable. "No?" He repeated it like he
was testing
an unfamiliar word. "But you were—you had two years left. You were brilliant at it. The essays, the arguments. Your father—" "My father wanted me to be a barrister." Rory picked up her glass again, mostly for something to do with her hands. "I didn't." Silas had gone still behind the bar, his attention focused on the glass in his hands with theatrical intensity. But she could
feel
him listening, cataloging, filing away every word. It was what he did. What he'd always done, even before she'd known enough to recognize it. Evan shoved his hands into his coat pockets. "So what do you do now?" "I deliver Chinese food." "You—" He stopped. Processed. Something like dismay
flickered
across his face. "That's temporary, though. Right? You're figuring things out, and then—" "No. It's what I do." She met his eyes, held them. "It's what I want to do." The lie tasted like ash, but she'd told it enough times that it almost felt true. She didn't want to deliver Chinese food. She didn't particularly want anything these days, and that was
precisely
the point. Wanting things meant vulnerability. Wanting things meant someone could use those wants as leverage, as weapons, as chains. Evan pulled out the stool beside her and sat without asking. Too close. The smell of his cologne—something new, something sharp and expensive—made her stomach clench. "Laila. Rory. Whatever you want me to call you. This isn't... this isn't you. Running away to London, working some dead-end job? You were going to do something important. Make a difference." "Things change." She turned back to her whiskey. "People change." "Do they?" His voice dropped lower. "Because I haven't. I think about you all the time. About us. About how good we were together before everything got..." "Complicated?" The word came out flat.
"Is that the
euphemism we're using?" "I was under a lot of stress. The business, the pressure from my father, trying to make partner before thirty. I know I wasn't always... I didn't always handle things well." He reached toward her wrist, and she jerked back so fast she nearly upset her glass. Silas's head came up, his body language shifting from neutral to alert in a heartbeat. Evan's hand retreated. "I'm better now. I've been in therapy. Real therapy, twice a week. And I've cut back on drinking. I barely touch the stuff anymore." He gestured at the bar with something like irony. "Which makes this an interesting choice of venue, I'll grant you." Rory traced the rim of her glass with one finger. "Why are you here, Evan? The Nest isn't exactly on the tourist maps." "Client meeting in Soho. It ran late." He paused. "I'm with Baxter & Cross now. Commercial litigation. Made senior associate last month." "Congratulations." "It's not what I wanted to tell you." He shifted on the stool, and his knee brushed hers. She moved her leg away. "Seeing you here, it
feel
s like fate. Like maybe we're supposed to get another chance. Start over. I could help you get back on track, maybe talk to some people at the firm about paralegal positions—" "I don't want your help." "But you're wasting yourself. Can't you see that? You're twenty-five years old, and you're delivering takeout for—what, minimum wage? Living God knows where, probably some bedsit in a rough neighborhood—" "I live upstairs." The words came out before she could stop them. "My flat's upstairs." Evan looked around the bar again, and this time she saw the calculation in his eyes, the assessment. Adding up the worn stools, the scuffed floor, the peeling paint on the window frames. Subtracting her value accordingly. "Right. Well. That's... I'm sure it's temporary." "Everything's temporary." Rory drained her whiskey and stood. "Good seeing you, Evan. I hope therapy works out." She grabbed her bag, but his hand shot out and caught her forearm. Not hard. Not like before. But the contact sent ice through her veins anyway. "Wait. Please. Just—have dinner with me. One dinner. Let me show you I've changed." She looked down at his hand, then up at his face. Saw the desperation there, the need. Not for her, not
really
. For absolution. For proof that the version of himself he
was building
in therapy sessions was real, was valid, was enough to erase the man who'd left bruises shaped like fingerprints and made her jump at sudden movements. Behind the bar, Silas set down his glass with a soft but deliberate sound. Rory peeled Evan's fingers off her arm one by one. "No." "Laila—" "My name is Aurora Carter. People who know me call me Rory." She shouldered her bag and turned toward the back of the bar, toward the stairs that led up to her cramped flat with its single window and persistent draft. "You never knew me at all." She felt his eyes on her back as she walked away, felt the
weight
of who she'd been, who he'd wanted her to be, who she'd tried so hard to become before she'd finally run. The stairs creaked under her feet. Behind her, she heard the scrape of a stool, the murmur of Silas's voice—low, pleasant,
utterly
implacable—suggesting that perhaps the gentleman might prefer a different establishment. Rory climbed toward her flat, toward the silence and safety of her small room, carrying the
weight
of all the years between the girl who'd loved Evan and the woman who'd learned to survive him.
