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.

Two people who parted on complicated terms are forced together again when one shows up unannounced at the other's flat. There's history between them — attraction, hurt, and things left unsaid. Write the scene from the moment the door opens. Use the codex entries above as your world reference for characters and setting. Only include the prose of the scene without any markdown or commentary.

The third deadbolt gave with a clunk that sounded louder than it should have, and when Rory pulled the door open, the cold came in first—Brick Lane in November, all damp brick and the ghost of cumin from the curry house downstairs. Then she saw him, and the cold became the least of it. Lucien Moreau stood on the landing as if he'd materialized there, which, knowing him, was not entirely impossible. Charcoal suit immaculate despite the rain that must have followed him from the street. Platinum hair slicked back, not a strand out of place. His ivory-handled cane planted before him, both gloved hands resting on the head of it, and his eyes—one amber, one black—taking her in with the unhurried thoroughness of a man reading a contract he intended to find fault with. "Hello, Aurora," he said. She did not let go of the door. "No," she said. "You haven't heard the question." "I don't need to. The answer's no." She started to swing the door shut, and the brass tip of his cane slid into the gap with a precision that told her he'd expected exactly this. The wood met the cane and stopped. Behind her, Ptolemy gave a low, interrogative meow from his perch on the windowsill, unbothered, the traitor. "Eight seconds," Lucien said mildly. "That is a personal record, I think. Last time you managed at least a full sentence before threatening me." "Last time you didn't disappear for three months." The words came out before she could dress them in something less honest, and she hated the way they hung there in the narrow hall, raw and unguarded. She watched something flicker across his face—the black eye stayed flat, but the amber one warmed a degree, which with Lucien was the equivalent of another man flinching. "May I come in," he said. Not really a question. "It is not the sort of conversation one has on a landing." "It's not a conversation we're having at all." "Then I will stand here in the wet and the smell of someone's overambitious vindaloo, and we will both pretend this is dignified." He tilted his head. "Eva is not home. Her wards are at half-strength and her cat is fond of me. I could have let myself in. I knocked, Aurora. Surely that counts for something." It counted, infuriatingly, for something. She stepped back. He came in the way he did everything—precisely, taking up exactly as much space as he intended and not an inch more—and she shut the door behind him, all three deadbolts going home out of habit. When she turned, he had already cataloged the room: the books stacked on every surface, the scrolls bundled in the corner, the half-eaten toast going cold on a plate of marginal notes. He set his cane against the table with the care of a man setting down something that could kill. "You're researching," he observed. "Eva's researching. I'm hiding." She crossed her arms. "There's a difference. Why are you here, Lucien?" He didn't answer at once. He took off his gloves instead, finger by finger, and the ordinary domesticity of the gesture undid something in her chest she'd spent three months reinforcing. She remembered those hands. She remembered too much. "I went to Avaros," he said. The name dropped into the room like a stone into still water. She felt the rings of it move through her. "You said you wouldn't." "I said I shouldn't." He folded the gloves into his pocket. "There is a difference, as you say." His eyes came up to hers and held. "I went because the man who is looking for you has a price on your head that doubled last month, and the only people who could tell me who set it are not the kind one finds in London. I have spent three months in places I swore I would never go again, Aurora, and I did it without telling you because if I had told you, you would have insisted on coming. And you would have died." Her arms were still crossed but the defense had gone out of them. "You could have written." "To say what? *Dear Aurora, I am in a realm where letters arrive on fire, having a marvelous time, do not avenge me if I fail to return*?" The corner of his mouth moved—not quite a smile, a thing he wore instead of one. "I did not write because I did not know if there would be an end to write you from." "And is there?" Her voice came out smaller than she wanted. "An end?" "There is a name." He took a step closer, and she didn't retreat, and the not-retreating felt like the most reckless thing she'd done all month. "And it is one you will not like. But that is not why I came here first, before Silas, before anyone." He stopped within arm's reach. Up close she could see the rain still beaded at his collar, the faint exhaustion under the polish, the way the black eye looked at her like she was the only fixed point in a turning world. "I came here first because for three months the thing that frightened me most was not the realm. It was that I would die in it without telling you the truth." The flat was very quiet. Somewhere below, a pan clattered. Ptolemy stretched and resettled. "Don't," she said. It came out as a warning and a plea braided together. "Don't say something you'll take back the second this is over and you've got your composure back. I've had enough of men who—" "I am not Evan." She went still. He had never said the name. She'd never told him to. "I know what you ran from," Lucien said, softer now, the four languages in him narrowing to this one careful English. "I know what it cost you to open that door eight seconds ago instead of slamming it. I am not asking you to trust me. I am only asking you to believe that when I left, it was not because I wished to be away from you. It was the only thing I had ever done because I could not bear the alternative." The crescent scar on her wrist itched the way it did when her pulse climbed. She looked at him—the impossible put-together wreck of him, soaked at the edges, having walked out of a hell to stand in a curry-scented hallway and tell her this. "You absolute idiot," she said. And then, because she was tired of doors, she closed the last of the distance herself.
