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 hummed its old song above the door, the same broken buzz it had hummed when Rory first moved into the flat upstairs. She'd come down for ice, only ice, because the machine on the third floor had finally given up its ghost, and she stood now at the threshold of The Raven's Nest with an empty bucket in her hand and the smell of rain on her coat. She did not expect to see Marcus Hale at the bar. He sat hunched over a tumbler of something amber, his shoulders broader than she remembered, his hairline retreating in a way that made him look both older and somehow more honest. Eight years. She counted them the way you count change in your palm, slowly, certain you've miscounted. Eight years since Cardiff, since the flat on Crwys Road with its damp ceiling and its broken radiator, since the nights they'd stayed up arguing about whether a person could ever really change or whether they only learned to perform their better selves more convincingly. "Marcus," she said, before she could decide whether to say anything at all. He turned. There was a moment—she watched it happen—when his face had no idea who she was. Then it arrived, recognition rolling in like weather. "God," he said. "Rory?" "In the flesh." "You—" He stood, knocked his knee against the stool, caught it. "You cut your hair." She touched it without meaning to, the black bob brushing her jaw. "Years ago." "It suits you." He was still looking at her like she was a word he'd forgotten and just remembered. "What are you—you live in London now?" "Upstairs, actually." She lifted the ice bucket as evidence, though of what she wasn't sure. "Above the bar. Long story." Silas, behind the counter polishing a glass that didn't need it, glanced up. He had a way of clocking everything without seeming to look at anything, his hazel eyes moving over Marcus once, twice, filing him somewhere. The silver signet ring caught the low light as he set the glass down. "Ice machine again," he said. Not a question. "Third floor's dead." "I'll send some up." He nodded, almost imperceptibly, toward the empty stool beside Marcus, and then he drifted to the far end of the bar to give them the only privacy a place like this could offer—the privacy of being ignored by a professional. Rory sat. She didn't decide to. Her body did it for her, the way bodies remember old shapes. "You look good," Marcus said. "You look—settled." "Do I." She wasn't sure settled was the word for living above a bar owned by a man whose past she only half understood, working deliveries for a Chinese restaurant, having left one city in the dead of night because of a man whose name she still couldn't say without her stomach tightening. But she let it stand. "What are you doing in London?" "Conference. Pharmaceutical regulatory stuff. Deeply boring." He turned the tumbler in slow circles. "I'm a consultant now. Can you believe it. Marcus Hale, who couldn't get out of bed before noon, billing by the hour." She could believe it and she couldn't. The Marcus she'd known had wanted to write. He'd had a novel he carried everywhere in a battered notebook, three chapters he'd revised so many times the pages had gone soft as cloth. He used to read passages aloud to her in that flat, watching her face for the place where the words landed. She'd loved him a little, then. Not enough to ruin anything, but enough to remember. "And the book?" she asked. Something passed over him. Quick, then gone, like a fish under ice. "The book," he repeated. "There's no book, Rory. There was never going to be a book." "You don't know that." "I do, actually. That's the thing about getting older. You find out what you were lying to yourself about." He drank. "I sold the notebook idea to myself for about a decade. Cost me nothing to keep believing it. And then one day I just—stopped paying." She thought of all the things she'd stopped paying for. The law degree her father had wanted, half-finished, a debt she still felt in his silences on the phone. The version of herself who would have stayed and fought, who wouldn't have run. "Maybe that's just honesty," she said. "Maybe it's not a tragedy." "You always did that." He smiled, but it was tired. "Found the door out of the dark room. You'd be three steps ahead while the rest of us were still feeling the walls." "That's a generous way of saying I never sat with anything." "Is it?" The bar settled around them, the low murmur of two other patrons in a corner booth, the soft clink of Silas arranging bottles, the rain finding its rhythm against the window glass. Old maps watched from the walls, their borders the borders of countries that no longer existed under those names. Rory looked at one—somewhere in Eastern Europe, the ink gone sepia—and thought about how everything got renamed eventually. Cities. People. The selves you used to be. "You disappeared," Marcus said. He said it lightly, but it wasn't light, and they both knew it. "After Cardiff. You just—went. No forwarding address. Eva said you'd moved but she wouldn't say where, and I figured—" He stopped. "I figured you didn't want to be found." "It wasn't about you." "I know." He nodded too quickly. "I know that now. I didn't then. I spent a stupid amount of time thinking it was something I'd done." She had not known that. It surprised her, how much it cost her to hear—the idea that her vanishing had cast a shadow she'd never accounted for, that she'd been so consumed with her own fleeing that she'd never imagined someone standing in the place she'd left, wondering. There had been a man named Evan and there had been a night she didn't talk about, and after that everything in Cardiff had become a thing to escape from rather than a person to say goodbye to. Marcus had simply been part of the city she'd had to burn down to get out alive. "It was bad, at the end," she said. "Not you. Just—the life. I had to leave it all at once or I wouldn't have left at all." He studied her. Whatever he saw, he had the grace not to ask after it. "You okay now?" "Getting there." And then, because the rain and the green neon and the eight years had loosened something: "I think I'm getting there." He raised his glass an inch. "To getting there." She had nothing to toast with, so she lifted the empty ice bucket, and he laughed, a real one, the laugh she remembered, and for a second the two people they'd been sat down with the two people they'd become, four ghosts at a bar in Soho, none of them saying what they'd missed. Behind the counter, Silas filled a fresh bucket with ice and waited, patient as the maps, for the past to finish its business.
