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 door of the Raven's Nest threw its color across the wet pavement, and Aurora Carter stood under it for a full minute before she went in. She had her delivery bag over one shoulder, the Golden Empress logo faded on the canvas, and she could smell the rain and the fried garlic still clinging to her coat. She told herself she only needed a drink before climbing the stairs to her flat. Silas would be behind the bar. Silas was always behind the bar. He looked up as the door opened, and his eyes moved over her the way they always did, quick and unhurried, reading the room and her in the same glance. Then he nodded toward the end of the counter. "You're not the only one who's come in wet tonight." She didn't understand him until she saw the woman on the stool. Eva had cut her hair. The long brown plait Rory remembered, the one Eva had chewed on during double maths in the fifth form, was gone, replaced by a sharp bob that ended at her jaw. She wore a navy wool coat buttoned to the throat and a wedding ring that caught the lamplight when she lifted her glass. For a second Rory thought she had walked into the wrong bar, into someone else's life. "Rory," Eva said. Just her name, the way she had always said it, with the sharp little lift at the end. "Hello, Eva." Neither of them moved. Silas set a glass down in front of the empty stool beside Eva without a word, then drifted to the far end of the bar and busied himself with a row of bottles, the discreet kind of attention that Rory had come to value in him over the past year. "You look well," Rory said finally, and heard how stiff it sounded. "I look tired. I've got a four-year-old who thinks sleep is a rumour." Eva turned her glass slowly on the wood. "You look the same. Which is annoying, because I've aged about forty years since you left." "I didn't leave you. I left Cardiff." "Same thing, when you don't answer the post." There it was, not even dressed up. Rory sat down, because her knees had decided for her. The stool was cold through her jeans. She thought of the letters, four of them in the first year, each one shorter than the last, and of the single card she'd sent at Christmas with nothing written inside but her name. She had opened Eva's last envelope in the hallway of this building and read it twice and then slid it into a drawer with the take-away menus, and she had not been able to say why. "I'm sorry," Rory said. Eva looked at her for a long moment. Her eyes, which had once been so quick to flash, were calm now, and that unsettled Rory more than anger would have. "Are you?" "Yes." "Good." Eva breathed out. "Because I needed someone to be sorry for something, and I'd rather it was you than me." Rory laughed, a short surprised sound, and Eva's mouth twitched in the corner, the first sign of the girl Rory had known. For a moment they were fifteen again, sharing a bag of chips on the sea wall at Penarth, planning the lives they were going to have when they got out. "Do you still want to be a barrister?" Eva asked. "God, no. I barely wanted it then." Rory picked at the edge of a beer mat. "Dad still asks me about it every Sunday like I'm about to file for a pupillage. Mum just asks if I'm eating." "Are you?" "Mostly out of other people's cartons." Eva glanced at the bag on the floor by Rory's feet. "You're delivering?" "Part-time. Yu-Fei pays me in noodles and gossip. It's honest work." "I never said it wasn't." Eva's gaze dropped to Rory's left wrist, to the small pale crescent there, the one from the broken greenhouse glass when they were nine. Rory pulled her sleeve down over it out of an old reflex. Eva saw. Of course she saw. She had always seen everything, which was why she had been the one to pull Rory out of Evan's orbit, the one to pick up the phone at two in the morning and say, *Get on the train, I'll be waiting at Paddington.* "Eva." Rory's voice came out rougher than she meant. "Thank you. For that. For Paddington. I never said it properly." Eva's hand moved across the counter and rested, briefly, on Rory's sleeve, right over the scar. "You said it by being alive, you daft cow. That'll do." Behind the bar, Silas set down a glass with a soft click. Rory noticed, without really meaning to, the silver ring on his right hand, turning once against the wood as he reached for a cloth. He did not look at them, but he was listening, the way he listened to everything, and she felt a strange gratitude toward him for keeping his distance. They talked until the rain stopped and the neon outside had begun to fade in the wet glass of the window. They talked about Eva's husband, a quiet man who fixed boats in Limehouse. About Rory's mother, who had started painting watercolours of the Taff. About the boy at school who had once put a frog in Eva's bag and how neither of them could remember his name anymore, though they both remembered the frog. When Eva finally stood and buttoned her coat, she paused. "Come to Sunday lunch," she said. "Bring something from the Empress. I'll pretend I don't know it's stolen." "It isn't stolen." "Then I'll pretend I don't know it's cold by the time you get there." Rory smiled. It hurt a little, the way a bruise hurts when you finally press it on purpose. "I'll come." Eva nodded once, as if that settled something, and walked out into the damp London night. The door swung shut behind her. Rory sat with her hands flat on the bar, staring at the two glasses, one still half full. "She's changed," Silas said quietly, coming down the bar with a dishcloth over his shoulder. "So have I," Rory said. He considered that, then set a fresh glass in front of her, the way he always did, without asking. "Yes," he said. "But you're still here to notice it."
