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 Golden Empress had sent her out with six bags of crispy duck to Berwick Street, and by the time Rory came down the back stairs into the Raven's Nest she still smelled of hoisin and wet tarmac. She meant only to cut through the bar on her way up to the flat. Friday nights were Silas' busiest, and she had learned to move through the crush with her helmet tucked under one arm like a rugby ball. The green neon over the door threw its sickly glow across the wet pavement outside, and inside the light was low and amber. Old maps of cities that no longer had those names covered the walls, along with black-and-white photographs of men in overcoats who never quite faced the camera. Silas stood at the far end of the bar, one hand on the pumps, the silver signet ring catching the light as he pulled a pint. He gave her the barest tilt of his head. *Evening, Rory.* She was nearly past him when a voice behind her said, "Aurora?" Nobody had called her that in years. Her mother did, when she was cross. Evan had, when he wanted her to feel small. She turned. A man sat at the end of the bar with a glass of something clear and fizzing, and it took her a full three seconds to build him into someone she knew. The hair was the first lie. Owen Pryce had worn his hair to his collar at nineteen, dyed a shade of blue he called *electric* and everyone else called *Smurf*. This man's was cut short and beginning to retreat at the temples. He wore a navy jacket that fit him properly, and there was a plain gold band on his left hand. "Owen," she said. "Christ." He stood, then seemed unsure what to do with having stood. He half-lifted his arms and let them drop. "It *is* you. I thought it was. You've cut your hair." "Six years ago." "Right. Well. I wouldn't know that, would I?" It was said lightly, and it landed anyway. Rory set her helmet on the bar. "What are you doing in Soho?" "Work drinks. Round the corner, some deal closing. I came in here to get away from them." He glanced at the maps, the photographs, the low ceiling. "Funny place. I like it." "I live upstairs." "You *live* here?" He laughed, and there it was, finally, the crack of the old laugh, the one that used to carry across the Students' Union like a dropped tray. It vanished as quickly as it came. "Of course you do. You'd find the one bar in London that looks like it's hiding something." Silas drifted down the bar, wiping his hands on a cloth, his left leg favoring itself in that slight hitch he never acknowledged. He set a coaster in front of Rory without asking what she wanted and poured her a half of the bitter she liked. His hazel eyes went once to Owen, once to her, and read the whole thing. Then he found something urgent to do at the other end. Rory sat. After a moment, Owen did too. "What are you drinking?" she asked, nodding at his glass. "Soda and lime." He turned it a quarter turn on its coaster. "Three years in March." She hadn't known there was anything to count. The Owen she remembered had once drunk a bottle of Buckfast on the roof of the law library and recited the Sale of Goods Act to the pigeons. She'd held his jacket while he was sick in the fountain outside Aberconway, laughing so hard she cried. "That's good," she said. "Really. I'm glad." "Are you?" He said it without heat, almost curious. "I'd understand if you weren't. I wasn't much fun to be glad about." "You were plenty of fun." "I was a lot of things." He smiled at the glass. "Some of them fun." The bar hummed around them, a cluster of men in shirtsleeves arguing about football, a woman laughing too loudly at a joke that hadn't been funny. Rory pressed her thumb against the small crescent on her left wrist, the old scar from the garden wall in Roath, a habit she fell into when she was deciding how much to say. Owen watched her do it. "You still do that," he said. "Do what?" "That. With your wrist." He looked away. "I used to think it meant you were about to tell me to sod off." "Sometimes it did." "Yeah." A pause. "I finished, you know. The degree. Then the training contract, and now I'm at a firm in Canary Wharf doing things with words like *indemnity*. Sarah says I've become the sort of person we used to make fun of." "Sarah's your wife?" "Two years. She's a paediatric nurse. She'd like you." He said it like an offering, then seemed to hear how it sounded. "I don't mean, I'm not—" "Owen." "I heard about Evan," he said, all at once, the words tumbling out like something he had been holding in his mouth all night. "Eventually. Not from you. From Gethin, at a wedding, two years after you'd gone. He said you'd left him and gone to London, and he said it the way you'd say someone had moved house. And I sat there with a plate of chicken and thought: I *knew*." Rory said nothing. Behind the bar, Silas set down a glass with exaggerated softness. "That night at the Philharmonic," Owen went on, staring at the counter. "The sleeve of your jumper had ridden up and there were those marks, four of them, in a row. I saw. You saw me see. And I made a joke about your taste in men, and I bought a round, and I got so drunk I don't remember getting home." His jaw worked. "That's what I did. I bought a round." "We were twenty." "Twenty's old enough to say *are you all right.*" "Yes," Rory said. "It is." He flinched, and she hadn't meant it cruelly, only truthfully, and she saw he understood the difference and was grateful for it anyway. She'd spent six years assembling a version of Cardiff in which nobody had seen anything, because that had been easier than a version in which they had and looked away. It was strange to find the second version sitting beside her in a good jacket, drinking lime and soda. "I would have lied to you," she said, more quietly. "If you'd asked. I'd have said I walked into a door. I was very good at it." "I know. I'd still rather have been lied to than have said nothing." "Would you?" He thought about it, honestly, the way the old Owen never did with anything. "No," he said. "Probably not. I'd have believed the door." She laughed, and it hurt a little, and that surprised her. She reached out and touched the back of his hand, just briefly, above the gold ring. "You're different." "Am I?" "You used to fill up a room. Now you look like you're trying not to take up your own stool." "That's not the worst description." He turned his hand over and squeezed hers once, then let go. "I broke a lot of things, Rory. Not people, I don't think. Mostly promises. But the shape of it was the same. I'd rather take up less space than do that again." "And me? Am I different?" He studied her, this stranger with his old friend's face. "You stopped apologizing," he said. "You used to say sorry to furniture. You've got a look like you know exactly where the exits are." "Occupational hazard. I deliver duck." "Do you like it?" "I like knowing where I'm going at the end of the night." His phone buzzed against the bar, and he glanced at it with obvious reluctance. Colleagues, a name, a string of impatient messages. When he looked back up, the moment had already begun to close, the way rooms do when the past has been allowed in just long enough. "I should go," he said. "You should." He stood and left a twenty under the glass, which she suspected was far too much. At the door he hesitated beneath the green wash of the neon, and for an instant she saw the nineteen-year-old with the terrible blue hair, grinning on the library roof with his arms flung wide. "I'm glad you got out," he said. "I never said that either." "Say it now, then." "I'm glad you got out." "Thank you," she said, and meant it, and the door swung shut behind him. Rory sat a while longer with her half-drunk bitter. Silas drifted back, took Owen's empty glass, and studied the twenty as though it might be forged. "Old friend?" he asked. "Yes." She turned the coaster over, then back. "No. I don't know. Something we didn't get to finish." He nodded slowly, as if that were a category he had filed many times. "Those are the worst kind," he said, and went to serve the football men.
