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 thunk that echoed down the narrow stairwell, and Rory pulled the door open expecting Eva, or the delivery she'd forgotten she'd ordered, or anyone at all except the man who actually stood there. Lucien Moreau looked exactly as he always did — which was to say, immaculate, infuriating, and entirely out of place against the peeling paint of the landing. Charcoal suit, no wrinkles, the ivory handle of his cane resting beneath one gloved hand. The bare bulb above him caught the platinum of his hair and turned it almost white. His mismatched eyes — one warm amber, one a black so total it seemed to drink the light — found hers and held. "Aurora," he said. Just that. Her full name, the way he'd always insisted on saying it, like the syllables were something he'd paid for and meant to use. For a moment she considered shutting the door. She got as far as tightening her grip on the edge of it, the wood biting into her palm, before something in her chest betrayed her and refused. "You're not supposed to be in London," she said instead. "And yet." He tilted his head, the faintest curve at the corner of his mouth. "May I come in? Or shall we conduct this on the stairs, where Mrs. Khatun three doors down can take notes?" Below them, the curry house exhaled its evening breath up through the floorboards — cardamom and frying onions, the muffled clatter of a kitchen. Ptolemy appeared from somewhere behind her ankles, tail high, and wound a slow figure-eight between her feet as if to vouch for the visitor. "Eva's not here," Rory said. "I didn't come for Eva." She knew that. Of course she knew that. She stepped back anyway, because the alternative was standing in the doorway pretending her heart wasn't doing something complicated and undignified, and she'd run out of other lies for the evening. Lucien crossed the threshold the way he did everything — without hurry, as though the room had been waiting for him. He took in the flat in a single sweep: the towers of books on every surface, the scrolls bleeding off the edge of the table, the research notes pinned three-deep to the wall above the radiator. The single lamp. The mug of tea going cold beside her laptop. "Eva still hasn't learned to file," he observed. "Eva doesn't believe in surfaces." Rory shut the door, slid the first deadbolt home, then stopped herself before the second. Force of habit. She didn't want him reading anything into how thoroughly she locked the world out these days. "What do you want, Lucien?" He turned, and the lazy amusement went out of him. That was the thing she'd forgotten — or made herself forget — about how he could change, how the polish could fall away in an instant and leave something underneath that was older and more careful and harder to look at directly. "You stopped answering," he said. "I stopped answering because the last time we spoke you put me on a train to Cardiff and told me not to come back until it was safe." She crossed her arms. The crescent scar on her wrist caught the lamplight, pale and old. "You don't get to decide that's complicated now just because you're standing in Eva's kitchen." "I never said it wasn't complicated." "You didn't say anything. That was the problem." Her voice came out steadier than she felt, which was a small mercy. "You handed me a ticket and a name that wasn't mine — Laila, you said, very good, very forgettable — and then you walked away down the platform like we'd concluded a transaction." Something moved across his face. Not quite a flinch. "It was the only way to keep them from finding you." "And it worked. Congratulations." She heard the bitterness and didn't bother to soften it. "I spent three weeks in a town I escaped at eighteen, sleeping in my old room, listening to my father lecture me about wasting my law degree, all so you could keep me safe. And you couldn't even — " She stopped. Pressed her lips together. Ptolemy had gone still by her feet, watching them both with the unbothered judgment of cats. "Couldn't what?" Lucien asked quietly. "Nothing." "Aurora." "You couldn't even pretend it cost you something." The words were out before she could catch them, and they landed worse than she'd meant them to, because they were true and because they sounded like exactly what they were. "You put me on that train like it was easy. Like I was a problem you were solving. And I let you, because I was scared, and because I — " She didn't finish that one either. She turned away instead, toward the window and the orange wash of Brick Lane below, the late buses and the boys outside the bagel shop and the rain that had started somewhere in the last few minutes without her noticing. Behind her, she heard the soft click of his cane being set against the table. Then the floor, which betrayed everyone in this flat eventually, gave a low groan under his weight as he crossed to her. He did not touch her. He was very careful, always, about touching her without permission — it was one of the things she'd held against him, and one of the things she'd never admitted she loved. "It did not look like it cost me anything," he said, "because I have spent thirty-two years learning to make sure nothing ever looks like it costs me anything. It is how someone like me stays alive in a city like this." A pause. His reflection appeared beside hers in the dark glass, half-lit, the amber eye gone to gold. "It is a poor habit to bring to the one person I did not want to lose." Rory closed her eyes. The rain ticked against the pane. "That's not fair," she said. "You can't just say things like that. Not now. Not after." "I'm aware." He sounded almost rueful. "I told myself I came with information. There's a man asking after you in Whitechapel — that part is true, and we'll deal with it. But I could have sent that in a message." His reflection didn't move. "I came up the stairs telling myself it was business. I knocked on the door and the moment you opened it I understood I had been lying to myself for a month." She opened her eyes. Met his, in the glass, because she wasn't yet brave enough to turn around and meet them directly. "I don't forgive you," she said. "No." "And I haven't decided whether I'm glad you're here." "That," Lucien said, with the ghost of that maddening smile returning to his voice, "is considerably more than I had any right to hope for." Ptolemy, having concluded that no one was going to feed him in the immediate future, stalked off toward the bedroom. The rain came harder. And Rory stood at the window beside a half-demon in a charcoal suit, neither of them moving, both of them watching the street, the silence between them no longer empty but full to the brim with everything they still hadn't said.
