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 sign above the door buzzed the way it always did, a faint stutter that Rory had stopped noticing months ago. She pushed through into the warm dark of the Nest with a stack of empty takeaway containers under one arm, meaning to drop them in the back, and stopped. A woman sat at the far end of the bar, under the map of the Bristol Channel that Silas had hung crookedly years ago and never straightened. She had her back to the room, one hand flat on the wood, the other turning a glass of white wine in slow circles. Her hair was cut short now, nearly to the jaw, and it had gone a shade lighter at the ends, but Rory would have known that stillness anywhere. Eva had never once in her life sat still. Rory's grip tightened on the containers. Behind the bar, Silas glanced up from the till, took in her face, and said nothing. He only lifted one eyebrow and went back to counting notes, his left leg stretched out stiffly beneath the counter, the silver ring catching the light on his right hand. "Rory," Eva said, without turning around. "I'd know that sigh anywhere." "I wasn't sighing." "You were breathing through your nose like a kettle. You've always done that when you're deciding whether to bolt." Rory set the containers on the nearest table because her hands needed to do something. Then she walked the length of the bar and sat two stools away, close enough to see the fine lines at the corners of Eva's eyes, which had not been there the last time. The last time had been a Tuesday in March, three years ago, in a hospital corridor in Cardiff that smelled of antiseptic and wet coats. Rory had walked out before the end of it. She had told herself she was going for air. "You look well," Rory said. "I look tired. Don't lie to me, it's embarrassing for both of us." Eva finally turned, and the bar light found her face, and Rory saw the thing that had changed. It wasn't the hair or the lines. It was the way she held herself, as if she had learned to take up less room so that no one could knock her over. The girl who used to climb the scaffolding at the old Cardiff docks, daring the whole estate to follow her, had been folded neatly away somewhere. "How's Tom?" Rory asked. "And the little one?" "Tom's fine. We separated in the autumn." Eva said it lightly, the way you'd mention the weather. "Amelia's with him in Bath. She's six now. She asks about you, sometimes. Asked if you were the lady who taught her to whistle through a blade of grass." Rory's throat closed. "I didn't know you'd split." "You didn't ask." It wasn't cruel. Eva said it with the faint, weary patience of someone who had already forgiven a thing and was tired of carrying the forgiveness around. "You never ask, Rory. You just leave the room." Silas set a glass of whisky in front of Rory without being asked and withdrew to the far end of the bar, where he began polishing something that didn't need it. Rory wrapped both hands around the cold tumbler and looked at the scar on her left wrist, the small crescent of white that had been there since they were eleven and had jumped from the wall at the top of the riverbank together, and she had landed wrong and Eva had torn her own sleeve to bind it. They had both been bleeding into the mud, laughing, too young to understand how close it had been. "Why are you here?" Rory asked. "Really." "I came back to find you." Eva smiled, but it didn't reach anywhere. "I've been in Lisbon for two years, doing a job I hated, and every postcard I wrote you, I tore up. Then last week I saw your name on a delivery manifest at the Golden Empress. Did you know Yu-Fei's been telling everyone you're the only courier in London who never gets lost?" "I like the routes," Rory said. It sounded thin even to her. "You like being useful, because being useful means nobody asks what you're carrying." Eva's voice softened. "I'm not angry. I was, for a long time. Then I just got old." Rory laughed, a short, startled sound, and to her horror her eyes stung. She looked down at the whisky. In the mirror behind the bottles, she could see both their faces, two women who had once shared a single bed in a cramped flat above a chip shop, now sitting under a green neon glow as if they were strangers who had both been told the same sad story. She had built a life out of leaving. The flat above the bar, the bicycle she never locked, the easy friendships she kept at arm's length. She had told herself it was freedom. Looking at Eva now, she understood that it had only been distance, and distance was a tidy word for a lot of things she had not wanted to name. "I'm sorry," Rory said, and the words came out rough and unpolished, nothing clever about them at all. "For the hospital. For all of it." Eva was quiet for a long moment. Then she reached across the gap between the stools and laid her hand over Rory's, carefully, over the scar. "I know," she said. "Drink your whisky, Rory. Then tell me what you've been doing with yourself, and we'll see if you can still make me laugh." Rory turned her hand over and held on.
