You are an expert fiction writer. Always keep the following rules in mind: - Write in past tense and use General English spelling, grammar, and colloquialisms/slang. - Write in active voice - Always follow the "show, don't tell" principle. - Avoid adverbs and cliches and overused/commonly used phrases. Aim for fresh and original descriptions. - Convey events and story through dialogue. - Mix short, punchy sentences with long, descriptive ones. Drop fill words to add variety. - Skip "he/she said said" dialogue tags and convey people's actions or face expressions through their speech - Avoid mushy dialog and descriptions, have dialogue always continue the action, never stall or add unnecessary fluff. Vary the descriptions to not repeat yourself. - Put dialogue on its own paragraph to separate scene and action. - Reduce indicators of uncertainty like "trying" or "maybe" When writing text: - NEVER conclude the scene on your own, follow the beat instructions very closely. - NEVER end with foreshadowing. - NEVER write further than what I prompt you with. - AVOID imagining possible endings, NEVER deviate from the instructions. - STOP EARLY if the continuation contains what was required in the instructions. You do not need to fill out the full amount of words possible.

The third deadbolt gave way last, and Rory pulled the door open with her shoulder still braced against it, the chain catching at eye level. Through the gap, a sliver of charcoal wool. A glint of platinum. An ivory cane balanced against the doorframe like he'd been waiting there for hours. "Hello, Aurora." She didn't slide the chain. "You don't get to use my full name like that. Not anymore." "I find I rather like it. It suits you better than the others." Lucien tilted his head, and the hallway light caught the strange split of his eyes — one amber and warm, one black as a drowned well. "Are you going to let me in, or shall we conduct this through three inches of door?" Ptolemy wound between her ankles, tail flicking with interest at the stranger. Traitor. She nudged the cat back with her foot and stayed where she was. "Eva's not here." "I didn't come for Eva." The words landed in her chest and stayed there, heavy and unwelcome. She let the silence stretch, let him stand in that grim corridor with the smell of curry rising through the floorboards, and she watched the muscle in his jaw tense the longer she made him wait. "Six months," she said. "Six months, Luc. Not a word. And now you turn up like you've just popped out for cigarettes." "I don't smoke." "That's not the point and you know it." He exhaled through his nose, the closest he ever came to losing his composure. "May I come in. Please. The matter is not one I want shouted across Brick Lane." She closed the door. For a moment she let him think she'd shut it on him entirely — let the deadbolt's silence do its work — then she slid the chain free and opened it wide. Lucien stepped through like he owned the place, which was his particular gift, making any room feel briefly leased to him. He took in the chaos of Eva's flat without comment: the toppled stacks of grimoires, the scrolls weighted down with mismatched mugs, the research notes pinned over every spare inch of wall. He set his cane against the bookshelf and turned, and for the first time she saw the rest of him properly. The suit was immaculate as ever. But there was a thinness to his face she didn't remember, a grey cast beneath the eyes that no amount of tailoring could press out. "You look terrible," she said. "And you look exactly the same. Maddening." He almost smiled. "Which is to say, very well." "Don't." She folded her arms. "Whatever this is, don't do the charm. I'm immune now. Built up a tolerance." "Have you." He didn't make it a question. He crossed to the window instead, looked down at the street, and she watched the line of his shoulders, the careful way he held himself like a man expecting a blow from a direction he couldn't predict. She remembered those shoulders. She wished she didn't. "You left me," she said, "on a rooftop in Whitechapel. Bleeding. You said you'd be ten minutes." "I know." "You didn't come back for three days, and when you did you wouldn't tell me where you'd been. And then you just — stopped. No message. No anything. I thought you were dead, Lucien. I went to the morgues. I checked the morgues, like an idiot." He turned at that. Something moved across his face, and it wasn't the practised regret she'd half-expected. It was rawer. "You checked the morgues." "Don't sound flattered." "I'm not flattered. I'm—" He stopped. His hand found the back of a chair and gripped it. "I left because there was a debt. My father's people called it in, and the only currency that satisfied it was my absence. From you specifically. They knew what you were to me. That made you a lever, and I would not be the handle they pulled." The flat went very quiet. Outside, a bus sighed past, and Ptolemy leapt onto the windowsill to watch it go. "You could have told me that," she said. Her voice had lost its edge; she hated how thin it came out. "You could have given me the choice." "You would have insisted on staying." "Yes." "And you would have died for it." "That," she said, "was mine to decide." He looked at her then, fully, both eyes fixed on her face, and she felt the old pull of it — the absurd, unfair gravity of him. She'd spent six months reasoning her way out of this feeling, building careful arguments against it, and he'd dismantled the lot in under five minutes simply by standing in Eva's cluttered front room and looking tired. "I didn't come to reopen old wounds," he said. "Then why did you come?" He reached into his breast pocket and drew out a folded square of paper. He held it, didn't offer it. "Because the debt is settled. As of three nights ago. I am no longer a liability you can be killed for." A pause. "And because in six months I have not gone a single day without composing a letter to you in my head and tearing it up before it reached the page." She didn't move. "That's a very pretty speech." "It's not a speech." His knuckles whitened on the paper. "It's the worst sentence I've ever said aloud, and I've said worse to men I was about to kill." A laugh broke out of her, startled and half a sob, and she pressed the back of her hand to her mouth to stop it. The crescent scar on her wrist caught the light. He watched it like he'd memorised it once, which he had — she remembered him tracing it in the dark, asking about the bicycle and the garden wall and the seven-year-old version of her who'd worn it home crying. "You can't just walk back in," she said. "I'm aware." "I'm serious, Lucien. You don't get to break my door down with a confession and expect everything to—" "I expect nothing." He set the folded paper on the table, smoothed it flat with two fingers, and stepped back from it. "I expect you to be angry. I expect you to send me away. I came because I would rather you do that to my face than to my silence." He retrieved his cane. "That is all. That is the entire reason." He was halfway to the door before she found her voice. "What's the paper." He stopped. "An address. Mine. The real one." His mouth twitched, rueful. "In case the tolerance fails."
