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 delivery bag was still slung over Rory's shoulder when she pushed through the door of the Nest, and it carried the ghost of ginger and hot oil. Rain had plastered her hair to her neck. Above the entrance the green neon sign buzzed its usual wet-electric hum, turning every puddle on Greek Street the color of pond water. She had meant to go straight up the back stairs to her flat. Instead she stopped at the bar for the free heat, and to let her hands stop shaking from the cold. Silas was polishing a glass with the slow, absent-minded care of a man who had once polished other things: ledgers, lies, the edges of a good cover story. He tipped his chin toward the far end. "Table by the Lisbon map. She's been asking about you." "Asking what?" "Whether a girl with black hair and a Cardiff accent works here." The silver signet ring flashed on his right hand as he set the glass down. "I said I couldn't discuss the staff." "I'm not staff." "That's what I told her, in a way that made it sound like a yes." He shifted his weight off the bad knee. "Go on. Nobody looks that nervous about a stranger." Rory turned. The woman at the table sat very straight, a glass of white wine untouched in front of her. She wore a charcoal coat that had never been rained on in its life, and her hair, once a shifting riot of magenta and bleach and whatever had been in the bathroom cupboard, was a smooth, disciplined brown pulled back at the nape. Only the hands were familiar. Long fingers, bitten nails now buffed and neutral. They turned the stem of the glass a quarter turn, then back. "Gwen," Rory said. Gwen's face did something complicated. "Aurora." Nobody had called her that in three years. It landed like a coin dropped down a well. "God. You look exactly the same." "I look like a drowned cat." "Exactly the same, then." Gwen smiled, and it was the wrong smile, small and careful, a smile with a lawyer behind it. The old one had been enormous and crooked and had usually preceded some catastrophe. "Sit? If you've got a minute." Rory sat. She set the delivery bag on the floor between her feet, like a shield, and immediately felt ridiculous. On the wall behind Gwen's head, a black-and-white photograph showed men in shirtsleeves on a Prague street in 1987, squinting at something out of frame. "How did you find me?" "I didn't. Not really." Gwen turned the glass again. "I'm at a firm on Chancery Lane. There was a drinks thing at a place off Old Compton Street, and I left early because I couldn't breathe in there, and I just walked. Then I saw the sign." She glanced up at the ceiling as if she could see through it to the neon. "Green. It's such a stupid color for a bar." "It's supposed to put people at ease." "Does it?" "No." They both laughed, briefly, and it died at once, leaving a silence with edges. "Chancery Lane," Rory said. "So you did it." "I did it." Gwen looked at her own hands. "Called to the Bar in September. Pupillage. I'm going to be a barrister, Rory. Can you believe that? Me. I used to think the law was just an elaborate way of making people wear wigs." "You told me once you'd rather eat your own guitar." "I sold the guitar." She said it lightly. Too lightly. "Paid a month of rent. Then another month. It's funny how quickly the things you swore you'd never give up turn out to be worth about four hundred pounds." Rory said nothing. She thought of the flat above the bar, the narrow bed, the single window that looked out on a brick wall and a drainpipe. She thought of Cardiff, of the lecture halls she had sat in with her father's expectations pressing on her like a hand between her shoulder blades. Gwen had been beside her then, drawing tiny monsters in the margins of her notes, whispering commentary on the lecturer's toupée. Gwen had been the reason she got through the first year. Gwen was the one who was supposed to leave. "I'd have said you were the one who'd end up in chambers," Gwen said, as though reading the thought. "You were so good at it. That thing you did, when you'd just go still and find the crack in an argument. I used to watch you do it and feel like I was standing next to a lock-picker." "I delivered forty-one containers of sweet and sour today." "Is that what the smell is?" "That's the smell." Gwen's mouth twitched. Then she put the glass down, finally, and the sound was very small against the wood. "I wrote to you. Eleven times. I counted afterward, because I needed to know how many I'd done before I stopped." "I know." "You know." "I got them." Rory's thumb found the crescent scar on her left wrist and pressed it, an old habit. "I read them all. I just couldn't—" "Answer." "Answer." The word was flat and true. "If I answered you, I'd have to say where I was, and if I said where I was—" "He'd find out." Rory looked up sharply. "I'm not stupid," Gwen said, very quietly. "I wasn't then, either. I just was a coward." She drew a breath. "I saw your arm at Freya's party. The second-year one. The sleeve slid up and you yanked it down so fast I thought I'd imagined it. And I told myself I had. I told myself for eight months. Then you were gone, and Evan was at my door asking if I'd heard from you, all charming, all worried, and I stood there and I said no and I thought, *good*, and I hated that I had to lie to a man who had been nothing but nice to me." "He was nice to everyone." "Yes." Gwen's voice cracked, just slightly, a hairline in good china. "That was the whole problem, wasn't it?" The rain ticked against the window. At the bar Silas had gone very still, in the way of a man who had spent decades pretending not to listen. Rory kept her eyes on the Lisbon map, on the faded blue of the Tagus. "You don't owe me an apology," she said. "I know. That's not why I'm saying it." Gwen pressed the heels of her hands briefly to her eyes, then took them away, and her face was composed again, smooth as the coat. Rory understood, with a small cold shock, how much effort the composure took. It was not the absence of the old Gwen. It was a wall built over her. "I'm saying it because I've been carrying it around like a stone in my shoe for three years, and you're sitting right here, and I might not get another chance." "Gwen." "I'm not asking you to say it's all right." "It isn't all right," Rory said. "But it isn't yours, either." She said it slowly, testing the weight of it, surprised to find it was true. "I'm the one who left without a word. I let you think you'd done something. I let *everyone* think it. It was easier than explaining." "Easier than trusting me." The sentence sat between them. Rory didn't flinch from it. "Yes." Gwen nodded, once, as if a verdict had been read and she'd expected it. Then she lifted the wine at last and drank half of it, and for a second, wiping her lip with the back of her wrist, she looked exactly nineteen, wild and stricken, all eyeliner and bad decisions. "Do you play?" Rory asked. "At all?" "No." "Not even at home?" "I haven't touched one since I sold it." Gwen turned the glass. "Sometimes I hear a song in the Tube, and my fingers actually move. Like a phantom limb. And then I get off at Chancery Lane and put on my lanyard." "That's a terrible thing to say." "It's a terrible thing to feel." Rory almost reached across the table. She got as far as sliding her hand a few inches over the scarred wood, and stopped, and Gwen looked at it, and neither of them moved. Three years lay in that gap. Rory wondered how far a person could walk from herself before there was no way back to the place she'd started. She wondered whether either of them had kept count. "I'm upstairs," she said finally. "Above the bar. Number four. If you wanted to—" She stopped, embarrassed. "There's a kettle. It's a rubbish kettle." Gwen's eyes brightened, wet and bright. "I've got a very early hearing." "Of course." "But I'd like to. Some other time." She pulled a card from her coat, cream-colored, engraved, and set it on the table with both hands, as if it might break. "That's my mobile. On the back. It's the real one. Not the one on the front." Rory turned the card over. On the back, in blue biro, in handwriting that still slanted left and still crossed its sevens: a number, and beneath it, a tiny, unmistakable monster with too many teeth. She kept her thumb over it a long time after Gwen had gone, after the door had sighed shut and the neon had swallowed the charcoal coat into the wet dark of Soho. Behind the bar, Silas set down his glass at last, said nothing, and slid a whisky across the wood without being asked.
