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 sign buzzed its small electric prayer above the door, and Rory had learned to stop hearing it months ago, the way you stop hearing your own pulse. She came down the back stairs from her flat most evenings just to sit at the end of Silas's bar with a glass of something she nursed too long, watching the maps on the walls yellow under the lamplight. Tonight the Nest was half-empty, the kind of weeknight quiet where the ice machine's hum became a presence in the room. Silas worked the far end, polishing a glass with the patient indifference of a man who had nothing left to prove to anyone, his signet ring catching the light each time his hand turned. Rory didn't notice the woman until she spoke. "They told me you'd be hard to find," the woman said, sliding onto the stool one space down. "But here you are. Tucked into the corner like always." Rory looked up, and for a long moment the name wouldn't come. The face belonged to someone she had known, but the version her memory offered was younger, softer, framed by a wild tangle of curls and a laugh that arrived before the joke had finished landing. This woman had the same dark eyes, but they had gone still and watchful. Her hair was cropped close, severe, threaded with a premature grey she made no effort to hide. She wore a charcoal coat that looked expensive and uncomfortable, the coat of a woman who dressed for rooms Rory had never been invited into. "Eva," Rory said at last, and the name tasted strange, like a word in a language she'd stopped speaking. "In the flesh." Eva signaled to Silas with two fingers and a nod, as though she'd done it in a hundred bars in a hundred cities, which Rory supposed she had. "Whatever she's having. And a whisky, neat." Silas brought the drinks without a word, set them down, and drifted away to the other end with the discretion of a man who had spent thirty years pretending not to listen. "Eight years," Eva said, turning the glass a quarter-turn on the wood. "Do you know that? I counted on the train. Eight years since Cardiff." "I know." Rory wrapped both hands around her own glass. The crescent scar on her wrist showed pale against her skin in the lamplight, and she watched Eva's eyes flick to it and away, the way they always used to. "I didn't know you were in London." "I'm not. Not really." Eva drank. "I'm passing through. I pass through a lot of places now." She let that sit, a small invitation Rory didn't take. "You never wrote back, you know. After. I sent you three letters to that flat in Roath and they all came back." "I left in a hurry." Rory heard the flatness in her own voice and didn't try to fix it. "You know why I left." "I do." Eva's jaw tightened, a small muscle working beneath the skin. "I'm the one who told you to go. I'm the one who put the train ticket in your hand and watched you not get on it for an hour. And then you got on it and you vanished, and I never heard from you again." The accusation in it was old and worn smooth, the way a stone is worn by being carried. Rory felt the familiar reflex to defend herself rise and then settle. There was no defense. She had vanished. She had been so consumed by the urgent labor of becoming someone Evan could not find that she had let everyone who'd known the old Aurora fall away, Eva included. Especially Eva, who had known her best. "I thought it was safer," Rory said. "For both of us. He came looking. He went to people. I didn't want him going to you." Eva nodded slowly, and Rory saw that she had already arrived at this understanding years ago, that she had not come here to be given a reason. She had come for something harder to name. "You look different," Rory said, to fill the silence. "I almost didn't know you." A thin smile. "You can say it. I look hard. I look like I've been hollowed out and lined with something colder." Eva turned the glass again. "Funny. I used to think you were the brittle one. Pre-law Aurora, all clenched up, hating every minute of it, your dad's voice in your ear about the bar exam. I thought you'd be the one who got swallowed whole by something respectable. And here you are, delivering noodles and living over a—" she glanced around the dim room, at the maps, at Silas— "over a bar in Soho. Looking, honestly, more like yourself than you ever did." The observation landed somewhere tender. Rory had not thought of it that way. She had thought of these years as a hiding, a holding pattern, a long held breath. But Eva was right that the clenched feeling was gone. Somewhere between the deliveries and the long quiet evenings down here, between Silas's unaskable questions and her own slow exhale, she had stopped bracing for a blow. "What happened to you?" Rory asked. It came out gentler than she'd meant. "You wanted to teach. You had that whole speech about Year Sevens and how you'd be the one who actually saw them." Eva laughed, short and without much in it. "I did teach. For two years. In Bristol." She drank again, deeper this time. "Then my mum got sick, and there were bills, and a man I shouldn't have trusted offered me a way to make them disappear. Funny how the people who offer to make your problems disappear always know exactly how much they cost." She set the glass down with deliberate care. "I'm not going to tell you what I do now, Rory. Not because I think you'd judge me. Because I think you wouldn't, and I'm not sure I could bear that." Rory let the silence stretch. Outside, the neon buzzed its small prayer. Silas, at the far end, held a glass up to the light and found it wanting. "I should have answered the letters," Rory said finally. It was not enough and they both knew it, but it was the only true thing she had. "I told myself it was about safety. Some of it was. But I think mostly I just wanted to stop being the person those letters were addressed to. And you were the last thing tying me to her." Eva looked at her then, fully, and for an instant the watchfulness fell away and the girl from Cardiff was there behind her eyes, the one who'd laughed before the joke had landed. "Yeah," Eva said softly. "I know. I did the same thing, you know. Just slower." She finished her whisky and stood, buttoning the expensive, uncomfortable coat. "I'm not staying. I just wanted to see that you were all right. You are, aren't you?" Rory thought about it honestly. "I'm getting there." "That's more than most people can say." Eva laid a note on the bar, far too much for two drinks, and didn't wait for change. At the door she paused, one hand on the cold metal, the green light washing her face. "Don't disappear again," she said. "Even if you can't write back. Just—don't make me wonder." Then she was gone, and the door swung shut, and the buzz of the sign was the only sound. Rory sat with her untouched drink and the warmth of an old name fading from the air, and did not move for a long while.
