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 green neon above the door threw its color across the wet pavement, and Aurora Carter stood under it for a moment longer than she needed to, a stack of insulated delivery bags still hooked over one shoulder. Golden Empress had kept her until nine. Her shirt smelled of ginger and hot oil. She pushed the door open. Inside, the Raven's Nest was doing its quiet Thursday business. Old maps curled on the walls beside black-and-white photographs of men in suits who had long since stopped mattering to anyone. Silas stood behind the bar with his weight on his right leg, polishing a glass with the careful patience he gave everything. The silver ring caught the light when he lifted his hand. He saw her, nodded once, and tilted his head toward the corner booth without saying anything. Silas had never needed to say much. Then she saw who was in the booth. Eva Morgan sat with her back to the wall, the way she always had, though the girl who used to sit that way had chewed her cuticles and watched the door with a nervous energy. This woman wore a charcoal coat with the collar turned up, and her black hair had been cut into a sharp bob that sat just above her jaw. She had a glass of sparkling water in front of her and a phone face-down beside it. Her left hand rested on the table, a thin gold band on the third finger. For a second neither of them moved. Rory's first thought was absurd: *she's got her mother's chin.* Her second was worse. *She knew I'd come here. Silas told her.* "Hello, Rory," Eva said. Nobody had called her Rory in four years. In London, she had become Aurora, or Carter, or nothing at all. The name landed in her chest like a dropped coin. "Hi, Eva." She slid into the booth opposite, and the vinyl stuck to the backs of her legs. "You look well." "I look like someone who has a mortgage." Eva almost smiled. "You look like you've been carrying bags of noodles across Soho." "Dumplings, mostly. Some of the noodles." Rory tried to laugh and failed. "What are you doing here?" "Silas called me. Last month." Eva glanced past her toward the bar. "He said you were living upstairs and working nights and that I should stop being stupid about it. He didn't use those words. He's very diplomatic for a man who used to break people's fingers for a living." "He never broke anyone's fingers." "No. I suppose he didn't need to." Rory looked at her friend's hands. The wedding band. The nails painted a pale, expensive pink, not a bitten edge anywhere. Eva had been the one who found the train timetable at fourteen, who had marked the Cardiff to Paddington line in highlighter and said, *We'll go together when we're grown*. Then Eva had stayed in Cardiff, and Rory had gone alone, and the highlighter had gone wherever such things go. "You got married," Rory said. "Two years ago. Daniel. He's a decent man. He reads the instruction manuals before he tries to assemble anything." Eva turned her glass slowly on its coaster. "I qualified as a solicitor last spring. Family law, mostly. Which I suppose is funny, considering." "It's not funny." "It's a little funny." Eva's gaze settled on Rory's left wrist, where the sleeve had ridden up. The small crescent scar showed pale against her skin. Eva had been there the day it happened, aged seven, when they had climbed the fence behind the allotments and Rory had landed badly on broken glass. Eva had held a tea towel to the wound and told her not to cry, and Rory had cried anyway, and Eva had cried too, out of sympathy. "You still have it," Eva said. "It's hard to lose." "Mm." A pause. "I didn't call, you know. After you left." "I know." "You didn't call either." "No." The word hung there. Behind the bar, a glass clinked. Somewhere in the back room, a door Rory had never seen opened and closed. She thought of the night she had left Cardiff, the bus station rain, the bruise along her jaw that she had covered with a scarf. Evan's voice through the flat door, sweet and reasonable, promising he'd be different. Eva's voice on the phone the next morning, steady as a tripwire: *Get on a train. Don't tell him where. Get on the train, Ror.* She had got on the train. She had not once, in four years, picked up the phone to say thank you, or sorry, or anything at all that might have required Eva to answer. "I was ashamed," Rory said. The admission surprised her. "Of how I left. Of what I left you with." Eva's expression did not soften, exactly, but something in it loosened. "Evan came round looking for you. Twice. Once with the police, once without." She let that sit. "I told him you'd gone to Scotland. He didn't believe me, but he got bored of asking." "Thank you." "Don't thank me. I'm not sure I did it for you." Eva's voice roughened. "I did it because you were the only person who ever made me feel like I'd get out of there. And then you did, and I was still in Cardiff, selling conveyancing to people in Penarth." "You didn't have to stay." "Oh, Rory." Eva finally laughed, low and tired. "I did, though. That's the thing about the people who get left behind. We're not stupid. We just don't have anyone holding a train ticket for us." Rory had nothing to say to that. She reached across the table instead and rested her fingers, very lightly, on the back of Eva's hand. Eva did not pull away. At the bar, Silas set down a fresh glass of sparkling water and a half-pint of bitter, then turned away to give them the room they needed. Rory watched his straight back and the faint hitch in his left stride as he walked toward the shelves of old books. The bookshelf did not move. She had never once seen anyone open it except him. "Stay for one drink," Eva said. "Just one. Then you can tell me everything you've become, and I'll pretend I'm not impressed." Rory thought about the bags waiting at the door, the flat upstairs with its single window over the alley, the years she had spent learning to be somebody no one from Cardiff would recognise. "One drink," she said. Eva pushed the bitter across the table. It was, Rory noticed, exactly the drink she used to steal from her father's study, in another life, when they had both been too young to know how little time they had.
