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 Raven’s Nest had begun to stutter in the rain. Aurora noticed it from across the street while she wrestled a paper bag of steaming containers beneath her coat. The sign blinked RAVEN’S N—then went dark, then returned in a sickly green wash that made the wet pavement look submerged. She should have gone around to the kitchen entrance. Silas hated delivery people tracking rainwater across the bar, and Yu-Fei’s orders were already late. But the front door stood open, spilling gold light and the low murmur of voices into Soho’s damp evening. Aurora pushed inside. Heat folded around her. Beer, old wood, fried garlic, the mineral smell of wet wool. Maps crowded the walls beside black-and-white photographs of men and women whose faces had been blurred by time or cigarette smoke. Behind the bar, Silas Blackwood glanced up from polishing a glass. His hazel eyes found the bag, then her face. “You’re late,” he said. “Traffic.” “You’re on foot.” “Pedestrian traffic.” One corner of his mouth lifted. “You’re learning.” Aurora set the bag on the counter and unwound her scarf. Her straight black hair clung to her jaw from the rain. The crescent scar on her left wrist showed briefly as she pushed back her sleeve, a pale mark she had carried since childhood and rarely noticed anymore. Silas reached for the receipt. “Table six.” “I know where table six is.” “Then why are you standing there?” “Because you’re blocking the way.” He shifted aside with his familiar slight limp. It was a small movement, almost imperceptible, but she had learned to read the old injury as other people read weather. Silas moved like a man who refused to give pain the satisfaction of being seen. Aurora lifted the bag and turned. Then the man at the end of the bar said her name. Not Rory. “Aurora?” The room did not change. The music continued, a blues guitar muttering beneath the talk. Someone laughed near the window. A glass broke in the kitchen and Yu-Fei shouted something in Cantonese. But Aurora felt the evening contract around that single word. She looked toward the voice. The man stood beneath a photograph of a railway station in winter. He had one hand around a tumbler of amber liquor and the other braced on the bar. His hair, once thick and blond, had thinned at the temples and gone the colour of ash. A narrow scar cut through his right eyebrow. He wore a dark wool coat buttoned to the throat, expensive enough to be understated. His face had altered in a hundred small ways. The softness around his mouth was gone. His eyes seemed set farther back, as if they had retreated from the world. But she knew him. “Daniel.” He smiled, and the expression hurt more than recognition. Silas looked from one to the other. His hand rested on the bar, silver signet ring catching the light. “You know each other?” “We went to university together,” Daniel said. Aurora held the delivery bag against her hip. “That’s one way of putting it.” His gaze dropped to the bag, then returned to her face. “You’re working here?” “Delivering for the restaurant next door.” “I thought you were going to be a barrister.” “I thought you were going to be a journalist.” He looked down at his drink. “Things change.” There it was. The sentence people used when they wanted to close a door without admitting they had slammed it. Aurora carried the order to table six. She placed the containers carefully before a couple who thanked her without looking up from their phones. When she returned, Daniel was still there. Silas had poured her a glass of water. She drank half of it in one swallow. “You haven’t changed,” Daniel said. She set the glass down. “That’s not true.” “No?” “I’m older. Tired. I have less patience.” “You used to have plenty.” “For you.” His jaw tightened. Silas turned away to serve a customer at the other end of the bar. He did not look at them, which meant he was listening to every word. Daniel moved to the nearest empty table. “Can we sit?” “We’re already standing.” “Rory.” The old name struck with the intimacy of a hand on the back of her neck. Eva had called her Rory. Her parents had called her Aurora when they were proud or disappointed. Daniel had used Rory when he wanted something and Aurora when he wanted to remind her that he knew the difference. She sat because she wanted to see whether he would flinch at being refused. He sat opposite her. Up close, the changes sharpened. The scar in his eyebrow. The faint grey at his temples. A deep vertical line between his brows. He looked like someone who had spent years arguing with himself and lost. “You vanished,” he said. Aurora laughed once, without amusement. “I left.” “You didn’t tell me.” “I left a note.” “You left a note on the kitchen table.” “Yes.” “It said, ‘Don’t contact me.’” “That was fairly clear.” “I thought something had happened.” “Something had.” His hand closed around the tumbler. Ice clicked against the glass. Rain slid down the front windows. Outside, umbrellas moved through the neon like dark, bobbing flowers. Daniel leaned forward. “I went to Cardiff.” “I know.” “You know?” “Eva told me.” “She said you’d gone to London. She wouldn’t give me your address.” “She was protecting me.” “From me?” Aurora watched his face. He had always been handsome in a way that made other people forgive him too quickly. Even now, with the tired skin and the scar, he carried that old gravity. A quiet confidence. The sense that his version of events would be more reasonable than yours, even when it wasn’t. “From the person you were becoming,” she said. His eyes flickered. “And what person was that?” “You know.” “No. I know what you accused me of. I don’t know what you believe now.” She had spent four years trying not to believe anything about him. Belief required attention. Attention became memory. Memory became the sound of a key turning in the lock at midnight, a glass striking the wall beside her head, his voice lowering into something calm and precise when he wanted to make cruelty sound like concern. “You were angry,” she said. “I was under pressure.” “You were angry.” “I’d lost my job. My father was ill. You were leaving for London without telling me—” “I told you.” “You told me after you’d made the decision.” “I told you three times.” “You were always halfway out the door.” “Because you kept making the room unsafe.” The words landed between them. Daniel looked toward the bar. Silas was wiping an already spotless patch of wood. His grey-streaked auburn hair caught the light, and his neatly trimmed beard gave nothing away. He had spent years around secrets. He knew when not to touch one. Daniel lowered his voice. “I never hit you.” Aurora felt the old coldness arrive—not fear, exactly. Something cleaner. A blade being drawn. “No,” she said. “You never hit me.” “I never threatened you.” “You said you’d make sure no one else would want me.” “I was drunk.” “You said I was lucky you loved me.” “I was hurt.” “You called my mother and told her I was having some kind of breakdown.” His face changed then. Not remorse. Not quite. Recognition, perhaps, of a room he had sealed years ago and now found himself trapped inside. “You were having a breakdown,” he said. Aurora stood. The movement made the chair scrape loudly across the floor. A few heads turned. The blues guitar went on murmuring, indifferent. Daniel reached for her wrist, stopping just before contact. For one second she saw the old shape of him overlaid on the new: the boy who had kissed her under the stone archway at Cardiff University; the man who had stood in her doorway with his fists clenched at his sides; the stranger in the wool coat whose hand hovered in the air because even he understood that touching her would be a mistake. “Don’t,” she said. He withdrew his hand. “I’m sorry,” he said. The words were so quiet she nearly missed them. Aurora stared at him. “For what?” His mouth opened. Closed. That was the problem with regret. It was often sincere and still insufficient. People apologised for the pain they could name. They left the rest buried beneath explanations. “For all of it,” he said. “That’s not an apology. That’s a weather report.” A muscle moved in his cheek. “What do you want me to say?” “You want me to tell you there’s a sentence that will return the years?” “No.” “You want me to say I understand.” “I want to know whether you hate me.” Aurora looked toward the photographs on the wall. In one, a woman stood beside a train, her face turned away from the camera. She seemed poised between departure and arrival, belonging to neither. “I don’t hate you,” Aurora said. Daniel’s shoulders loosened. She continued, “That’s the worst part.” He looked down. “I hated you for a while,” she said. “It was useful. It gave the whole thing a shape. Then I got tired of carrying it. I had work. Bills. A life. I had to become someone who could walk into a room without checking the exits.” His eyes lifted. “Did you?” “Yes.” “Are you happy?” The question angered her more than it should have. Happiness, in his mouth, sounded like a verdict he still had the authority to deliver. “I’m here,” she said. “That isn’t an answer.” “It’s the one you get.” Silas approached with the receipt from table six. “Yu-Fei’s asking whether the order arrived.” “It did,” Aurora said. “Then you can go.” Daniel looked at him. “I’m not stopping her.” Silas’s gaze settled on him. “Good.” There was no threat in the word. That made it worse. Aurora reached for her coat. Daniel stood too. “I heard about your father,” he said. Her hand paused on the sleeve. “From whom?” “Your mother. A few years ago. I sent flowers.” “I never saw them.” “I didn’t put my name.” “Why?” “I thought you’d send them back.” “You should have put your name.” “I was trying not to intrude.” She studied him. The rain had darkened his shoulders. He looked older than he had ten minutes ago, and younger too. For the first time, she saw not the monster she had made him into, nor the wounded man he wanted to be, but an ordinary person who had done terrible things and would have to live inside them. That was all anyone got. “Is he all right?” Daniel asked. “My father?” “Yes.” “He’s fine.” “Good.” She buttoned her coat. Her fingers were steady. At the door, she glanced back. The green sign flickered above the glass, bathing Daniel’s face in a brief, unnatural colour. For an instant he looked almost like the boy she remembered, standing beneath the university arch with rain in his hair and hope arranged carefully across his mouth. Then the light failed, and he became a stranger again. “Goodbye, Daniel.” He did not ask her to stay. “Goodbye, Aurora.” Outside, the rain had strengthened. Aurora stepped into it without opening her umbrella. Cold water struck her face, ran down the back of her neck, and cleared the bar’s heat from her skin. Behind her, the Raven’s Nest door shut. The green neon stuttered once above the street, then held.
