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 long moment before she went in. Her delivery bag hung heavy off one shoulder, still smelling of ginger and hoisin from the Golden Empress. She had meant to go straight up the stairs to her flat. Instead she pushed through the door of the Raven's Nest because her feet had decided before the rest of her did. Inside, the bar was nearly empty. Old maps curled on the walls, and black-and-white photographs of men in overcoats watched from the frames with the patience of people who knew how things ended. Silas was behind the bar, polishing a glass with the careful unhurried motion she had come to find steadying. He glanced up, nodded once, and then his eyes went past her to the corner booth and stayed there a beat too long. She followed his look. A man sat with his back to the wall, a half-finished pint in front of him and a rain-darkened coat folded on the bench beside him. He had been handsome at nineteen, in the way that boys from the Cardiff valleys were handsome when they didn't yet know it was a currency. Now his face had settled into something sharper. There was grey at his temples. There was a stillness in him that she didn't recognise. "Rory," Owen Pryce said. Nobody had called her that in three years. Not since Eva, not since the last phone call she had let ring out. She heard it land in her chest like a dropped stone. "Hello, Owen." "Christ. It is you." He stood, and she saw him decide not to hug her, saw the small adjustment of his shoulders that meant he had read her face and understood the rules. "Sit down. Please. I'm not going to make a scene." "I wasn't worried about a scene." "No. You never were." She sat across from him. Silas set a glass of red wine in front of her without asking, then drifted back toward the far end of the bar, close enough to hear but polite enough to pretend otherwise. For a while neither of them spoke. The rain ticked against the window. Somewhere in the back a fridge hummed. "You look well," Owen said finally. "I look tired." "That too." His gaze drifted, not rudely, to her left wrist, to the thin pale crescent just below the cuff of her jumper. She had stopped noticing it years ago. He had not. She knew it from the way his eyes settled there, as if the mark were a sentence he had once learned by heart. "You remember the fence," he said. "I remember you screaming louder than I did." "You weren't screaming. You were holding your arm out like it belonged to someone else and telling me it was fine." He turned his pint glass slowly on its mat. "I thought you were going to die. I was nine. I ran the whole length of Cowbridge Road with you bleeding into my shirt." "You were a good friend." "I was a terrible friend." He said it without self-pity, the way someone might state the weather. "I stopped ringing. After your dad. After Cardiff. I didn't know what to say, and then it had been too long to say anything at all." She had expected anger, if she'd expected anything. Instead she felt the familiar ache of a story with no clean edges. She thought of her father in his good suit, the courtroom voice that had gone quiet at the kitchen table. She thought of Evan's hand closing on her wrist in a flat in Canton, the same narrow place where the old scar lay, and how she had told herself for months afterward that the two marks were unrelated. "It's all right," she said, and heard how little she meant it. "It isn't. But thank you for saying so." He looked up. "What happened to you, Rory? Really. Eva said you'd gone to London and that was the last anyone heard." She could have made something light up. A job, a flat, a man who didn't matter. Instead she turned her glass by its stem and watched the wine tilt. "I stopped being the person who was going to be a barrister," she said. "I stopped being anyone's good idea. I deliver dumplings to people who don't look at me. I sleep above a bar in Soho and I've learned to check the locks twice." She smiled, and it hurt a little at the corners. "I'm good at it, Owen. That's the strange part. I'm very good at staying out of sight." He was quiet. Behind the bar, Silas set down a bottle with a soft, deliberate click, and Owen's eyes flicked toward the sound and back. "Is he dangerous?" Owen asked quietly. "No," she said. "He's the only one who ever asked me what I wanted without wanting something back." Owen nodded slowly, as if that were an answer he could live with. "I'm glad you have that." "Are you?" "Yes." He hesitated. "I'm sorry I wasn't there. For the bits that mattered." The words sat between them, plain and heavy. She felt the old fence splinter under her palm, the blood warm down her arm, a small boy running with her through a street that had since been paved over and renamed. "I know," she said. "I was waiting for you to come anyway." He laughed, a rough sound, and wiped one eye with the heel of his hand. "God, we were stupid." "We were nine." "We were twenty-two, Rory. Some of us are still stupid." She finished her wine. When she stood, her bag bumped against the table and the old wrist throbbed faintly in the cold. Owen rose too, awkwardly, and for a moment they simply looked at each other, two people who had once known every crack in each other's lives and now could barely recognise the outlines. "Take care of yourself," he said. "You too." She walked to the door. Under the green glow of the sign, she glanced back. Owen had sat down again, his face bowed over his untouched pint. Silas was watching her from behind the bar, and he gave her the smallest nod, the kind that meant *I see you, and I'm not going to ask.* She pushed the door open and stepped out into the rain, and for the first time in years the cold felt like something she could walk through.
