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 rain had found the back of Rory's neck somewhere between Old Compton Street and the green glow of the Nest's sign, and by the time she pushed through the door she was carrying a damp paper bag of Golden Empress noodles she had not been paid to deliver. Yu-Fei would have scolded her for taking the long way. Rory had taken it anyway, because the short way ran past the Italian place where she used to meet people, and she had not wanted to see whether any of them still did. The bar was warm and low-lit, smelling of woodsmoke and bitter orange. Old maps covered the far wall, their coastlines yellowed like old teeth, and the black-and-white photographs hung between them in plain frames, faces she had long ago stopped trying to name. Silas stood behind the bar with a cloth in one hand, polishing a glass that did not need it. He looked up, caught her eye, and tilted his head toward the corner booth in a way that meant nothing and everything at once. She turned. For a moment she did not recognise the woman in the booth, and then she did, and the recognition hit lower than she expected, somewhere beneath the ribs. Eva had always been the loud one. At fifteen she had climbed the wall behind the Cathays library to sit on the roof and shout at the buses. At nineteen she had been the one who held Rory's hair back in the toilets of the Taf Inn and said, *You're not going back to him, do you hear me? You're getting on a train.* Now her hair was cropped close to her skull, the colour of wet sand, and she sat very still with both hands wrapped around a glass of mineral water. A slim gold band caught the light when she lifted the glass. Her coat, folded over the next seat, was the kind of camel wool that did not come from Cardiff or from anywhere Rory could afford. "Hello, Rory," Eva said. "Hello." Rory did not sit. She stood with the bag of noodles dripping gently onto the floorboards and felt absurdly like a courier again, which, she supposed, she was. "You look well," Eva said. "So do you." It came out flat, and Rory heard it, and did not take it back. "You're married." "Three years." Eva turned the ring with her thumb. "His name's Gerald. He's in shipping. He's kind, which I know you'll think is a cop-out." "I didn't say anything." "You were going to." A thin smile. "You always had that face. The one that means you're already three steps ahead and waiting for me to catch up." Rory sat down then, because her legs had decided it for her. The vinyl of the booth was cool through her jeans. Across the room Silas set a short glass of whisky on the bar and did not bring it over, though his eyes stayed on the booth with the patience of a man who had spent most of his life watching rooms for what might go wrong. "I got your postcard," Eva said. "The one with the Thames on it. You wrote *Still alive, don't come looking* on the back." "I meant it kindly." "I know you did." Eva's voice softened, and that was worse. "I didn't come looking. I thought about it. I drove to Pontcanna once and sat outside your mum's house for an hour. Then I drove home." The bar was quiet except for the low murmur of a couple at the window and the tick of the old clock above the door. Rory looked at the scar on her left wrist, the small crescent she had earned at nine years old on a broken fence, and thought of how often she had covered it in the years since, with cuffs and bracelets and once, in a bad month, a strip of tape. "You told me to run," Rory said. "And I did, and I never once asked what it cost you to stay." Eva was quiet for a long time. When she spoke her voice had gone thin. "It cost me you." "That's not fair." "No. None of it was." She lifted the water glass and set it down again without drinking. Her hand was steady, but Rory noticed the effort in it. "I used to think if I got you out, I'd finally be the person who did something right. Then I got married and got a house in Surrey and started forgetting the bus fare, and Evan's name stopped making me sick. And I hated that more than anything." Rory wanted to tell her that forgetting was not a betrayal, that she herself had spent four years trying to forget and had only succeeded in rearranging the pieces. Instead she said, "Does Gerald know about him?" "Gerald knows everything. That's the trouble with Gerald." Eva almost laughed. "He's very patient with me. He waits. Sometimes I think he's just waiting for me to finish being someone else." Across the bar, Silas finally moved. He came around the end of the counter with the slight favour of his left leg and set a second whisky in front of Rory without asking, then placed a hand briefly on the back of the empty chair beside Eva. He said nothing. He did not need to. Rory had seen him do this before, with other people in other booths: a silent statement that the room was watched and the watching was on their side. Eva glanced up at him and something passed between them, recognition or permission, and then Silas withdrew to the bar. "Your Silas," Eva said. "He still looks like he could break a man's arm and apologise for the mess." "He's not mine." "Everyone's yours, Rory. That was always your problem." Eva finally drank, a small sip. "Are you happy?" The question hung between them, as simple and as impossible as the rain outside. Rory thought of the flat above the bar, the bike she rode through traffic at night, the careful silence she kept with her own mother on Sunday calls. She thought of Eva on the roof of the library, shouting at the buses. "I'm alive," she said at last. "I don't know if that's the same thing." "It's a start." Eva reached across the table, hesitated, and then covered Rory's left hand with her own, her thumb resting carefully over the scar. Neither of them moved. The clock ticked. Outside, the green sign buzzed faintly against the wet glass. "Stay for one drink," Eva said. "Just one. Tell me what you've become." Rory looked at the whisky, at the paper bag going soft at the edges, at her oldest friend's ringed hand on her wrist, and understood that she had no ready answer. She picked up the glass. "Ask me again in an hour," she said.
