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 hummed above the door of the Raven's Nest, throwing a sickly emerald wash across the wet pavement, and when Rory pushed inside, shaking the rain from her coat, she did not expect to see anyone she knew. That was the point of the place. People came to Silas's bar precisely because no one expected to find them there. But there she was, at the far end of the bar, beneath a black-and-white photograph of some harbor that had long since changed its name—Eva. Rory stopped just inside the threshold. For a moment she thought she'd mistaken a stranger for a memory, the way you sometimes did with the dead. But no. The set of the shoulders was the same, the way Eva held a glass with both hands as though warming them against it. Only the hair had changed: cropped now, severe, where it had once fallen in tangled curls down her back. And the clothes—a tailored charcoal coat, expensive, the kind of thing the Eva of seven years ago would have laughed at, would have called a uniform for people who'd given up. Rory crossed the floor before she could decide whether she wanted to. "Eva." The woman turned. There was a half-second delay, a flicker behind the eyes—recognition arriving like a train at a distant platform, slow, then all at once. "God," Eva said. "Rory." Neither of them moved to embrace. That told Rory more than anything else could have. "I didn't know you were back in London," Rory said, sliding onto the stool beside her. The leather was cracked and cold. "I'm not, really. Two days. Meetings." Eva turned the glass a quarter-turn on its coaster. "I didn't know this was your—" She gestured vaguely at the maps, the dim amber light. "Your kind of place." "I live upstairs." Eva blinked. "Here? Above a bar in Soho?" "It's not what it looks like." "It looks like exactly what you ran to London to find." Eva said it lightly, but it landed hard, the way a thing only can when it's true and the person saying it knows it's true. Rory felt the old reflex—the one Eva had always been able to summon in her, the urge to explain herself, to lay out the case like her father standing before a jury. She let it pass. "What are you drinking?" Rory asked instead. "Something I can't pronounce. The man behind the bar recommended it." Eva nodded down the counter to where Silas stood with a towel over his shoulder, polishing a glass that had surely been clean for an hour. He met Rory's eyes for the briefest moment, read whatever was written on her face, and looked away with the practiced indifference of a man who had spent thirty years pretending not to notice things. "He has a kind face," Eva went on. "And the most untrustworthy eyes I've ever seen." "That's about right." Silas brought Rory a whisky without being asked, set it down on the worn wood, and withdrew. The two women sat in the small island of their silence while the rain ticked against the window and a couple in the corner murmured over a candle that wasn't really a candle, just a bulb pretending. "You cut your hair," Rory said. "Years ago." Eva touched the back of her neck, an unconscious gesture. "You'd be amazed how seriously people take you when you stop looking like someone they want to take care of." "I always took you seriously." "You took me as I was. That's different." Eva smiled, but it didn't reach anywhere. "You were the only one who did, actually. Which is why—" She stopped. "Which is why what?" Eva looked into her drink as though the rest of the sentence might be floating there. Rory waited. She had learned to wait; it was the single most useful thing she'd taught herself in seven years, the discipline of the unfinished silence, letting it stretch until the other person reached out to fill it. But Eva was good at silence too, now. That was new. "You stopped calling," Rory said finally. "You did." "After. After you stopped." The whisky was peat and smoke and it burned in a way she was grateful for. "I called you the night I left him. The night you told me to get on the train. You said you'd meet me at Paddington. You weren't there." Eva went very still. "I waited two hours," Rory said. "I sat on my suitcase by the departures board with a black eye I'd covered with the wrong shade of concealer, and I told myself the trains were delayed, you'd got the time wrong, something. And then I rang and rang, and the next morning there was a text. Just—'So glad you're safe. So sorry. Explain later.' You never explained later." "Rory—" "I'm not angry." And the strange thing was, she wasn't, or not anymore; the anger had calcified years ago into something quieter and harder to name. "I built a whole life out of that night. I just always wondered where you were." Eva was quiet for a long time. When she spoke, her voice had lost its careful polish, and underneath it Rory heard the girl she remembered, the one who'd cried at films and stolen chips off Rory's plate and sworn, drunk and seventeen, that they'd never become the kind of women who let each other down. "I was at a hospital," Eva said. "Not for me. For my mother. She'd taken the pills that night—the same night, I swear to God, the same hour you rang—and I was holding her hand in a corridor in Leeds while a nurse asked me her date of birth and I couldn't remember it. My own mother's birthday. And my phone kept lighting up with your name and I—" She pressed her lips together. "I made a choice. And then I couldn't face telling you what the choice had been, because how do you say that? How do you say, I'm sorry, I had to let you down because someone else was drowning louder?" The not-candle guttered in the corner. Somewhere behind the bookshelf at the back of the room, Rory knew, was a door, and behind that door men like Silas traded secrets that decided things in countries she'd never see. And out here, over two glasses, two women were trading the only secrets that had ever really mattered to either of them. "She lived," Eva added. "If you were wondering. She's in Spain now. She gardens." "I'm glad." "I know you are. You were always glad about everything. It used to drive me mad." Eva laughed, wet, and wiped under her eye with a knuckle. "Look at us. You're a barmaid with a flat full of secrets and I'm a woman who flies in for meetings. We were going to be—God, what were we going to be?" "Important," Rory said. "We were going to be terribly important." "We were going to be free." Rory turned her glass and watched the light move through it. The crescent scar on her wrist caught the lamplight, pale and old. "Maybe we are," she said. "Just not the way we drew it up." Eva reached over then, finally, and laid her hand over Rory's—over the scar, over all of it—and neither of them spoke. The rain kept on. Silas, down the bar, polished his already-clean glass and watched the door, the way he always did, for whoever might come in next out of the dark.
