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 door opened on a gust of October rain, and Rory did not look up at first. She was wiping down the far end of the bar, the cloth moving in slow circles over old oak that had been polished by forty years of elbows. Silas had taught her to keep her eyes on the work when she wanted to listen, and to listen when she wanted to be left alone. So she heard the heels on the wet boards, the hitch of a breath, and then a voice she had not heard in four years saying her name the way nobody else in London ever did. "Ror." She set the cloth down. Under the green glow of the neon sign coming through the window, the room seemed to tilt and settle. Eva stood just inside the door, shaking water from a navy umbrella, and for a moment Rory saw only the girl from Cardiff, the one who had dared her across the railway fence behind the Splott allotments when they were nine. Then the light shifted, and the girl was gone, and a woman stood in her place. Eva's hair was cropped short, close to the skull, which made her face look older and more deliberate. She wore a charcoal coat that fit her too well to be a gift from anyone who didn't have a say in the cut. There was a thin gold band on her left hand. Rory noticed it the way she noticed exits and the weight of cash in a till. "Hello, Eva." "You're behind a bar." "I'm usually behind a bar. Upstairs is a flat, so it's not much of a leap." Rory heard how brittle it sounded and did not try to soften it. "What can I get you?" Eva took a stool near the window, where the rain made running rivers of the glass and the lights of Old Compton Street bent into smears. "Something without alcohol. I've been three years sober." "Three years." Rory reached for the sparkling water, the lime, a clean glass. Her hands knew this work. Her mind kept snagging on the number. Three years was a long time to be sober. It was a long time to be anything. "That's good. That's really good." "It was boring, mostly. Then it wasn't." Eva turned the glass slowly on its coaster. "I'm getting married in the spring. Richard. He's a surveyor, very reliable. Mother adores him, which is the highest praise she gives." "Congratulations." "You don't have to sound like a hostage." Rory laughed, despite herself, and the sound surprised them both. For a second the old current ran between them, quick and easy, and she remembered the two of them on the back step of Eva's mum's house, sharing a stolen cigarette and planning a life that did not include Cardiff or anybody's rules. Then the memory swung round and showed her the other side of it: a flat in Canton, a locked bathroom door, Evan's voice on the stairs, and Eva's car idling in the rain with its headlights on, Eva's hands gripping the wheel so hard the knuckles had gone white through the glass. Eva had come for her that night. She had come for her in the middle of the night and driven her to a train station and said, *You're going to London. You're going to be someone who doesn't have to explain the bruises.* And Rory had gone, and for the first year she had answered every call. Then she had stopped. It had not been a decision so much as a flinch. Every time the phone lit up with Eva's name, she heard the engine and saw the headlights, and she could not bear to be reminded of what she had been, or of how close she had come to staying. "I should have called," Rory said. Eva was quiet for a long moment. "You should have. I called you on your birthday. I called when Dad was in hospital. I left a message the week you got the flat, which I only know because your sister told me." She set the glass down without drinking. "I didn't ring to make you feel bad, Rory. I rang because I missed you. That's all it ever was." The bar's old clock ticked above the photographs, black-and-white faces of men and women who had drunk and argued and died in this room long before either of them was born. Rory picked up the cloth again, folded it, put it down. Her left wrist ached faintly where the crescent scar sat pale against the skin, the mark of the glass-topped table she had gone through at seven years old. Eva had been the one to hold a tea towel to it while they waited for her mother to come home. Rory found herself looking at it now, as if it might explain something. "I'm not the person you knew," she said quietly. "I don't know if I'm supposed to be." Eva studied her with the same frank attention she had once given a bruised sky or a bad sum. "You haven't changed as much as you think. You've just learned to hide it better." "That's not comforting." "It wasn't meant to be." Eva reached across the bar, slowly, and rested two fingers over the scar on Rory's wrist. The touch was light, almost tentative, the way someone might test ice. "It's still there, though. Whatever you've put over it." Rory did not pull away. Somewhere behind the bar, through the door to the back room hidden behind the bookshelves, she heard Silas's uneven footstep, the small hitch of his bad knee on the stairs. He would not come out. He never did when someone she loved was in the room; he gave her the space to decide what she wanted to carry. "Will you stay?" Rory asked. "For one drink. The real kind, if you like." Eva smiled, and for an instant the nine-year-old was back in her face, bold and unafraid. "Only if you pour it yourself." Rory reached for the bottle with her right hand, the one that did not shake, and poured.
