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 green neon buzzed above the door of the Raven's Nest, throwing a sickly glow across the wet pavement. Aurora pushed through, shaking the rain from her jacket, and the warmth inside hit her like a held breath finally let go. She'd not meant to come. The flat upstairs sat empty and quiet, and she'd told herself she only needed a drink before sleep. But the bar was half-full, the murmur of strangers a comfort, and she slid onto a stool at the far end where the maps curled at their corners against the wall. "Whisky. Whatever's open." The bartender poured without comment. She'd seen him before—Silas, the owner, though they rarely spoke beyond rent and weather. He set the glass down, then drifted off to attend a couple by the window. Aurora turned the whisky in her hand and watched the amber catch the light. "Rory? My God. Rory Carter." The voice came from her left, and something in her stomach dropped before her mind caught up. She turned. A woman stood there, holding a wine glass, her hair shorter than Aurora remembered, copper streaked now with a deliberate silver. The years had carved fine lines at the corners of her eyes, but the eyes themselves were the same—pale grey, quick, always reading a room before they read a person. "Priya." "It is you." Priya laughed, the sound brighter than the situation warranted. "I thought I was hallucinating. Eight years and you turn up in some Soho hole drinking alone." "Nine." "What?" "It's been nine years." Aurora gestured to the stool beside her. "Sit, if you're going to." Priya sat, arranging herself with a care that hadn't existed in the girl Aurora used to know. The Priya from Cardiff had worn charity-shop coats and laddered tights and didn't care who saw. This woman wore a coat that cost more than Aurora's monthly wage and a watch she kept glancing at without meaning to. "You look well," Priya said. "I look tired." "You look like you've been somewhere." Priya's eyes moved over her, cataloguing. "There's a thing about you now. A hardness. The Rory I knew used to apologise to doors she walked into." Aurora drank. "People change." "They do." Priya turned her own glass. "I'm in London now. Have been for years. I run a consultancy—media strategy, crisis communications. Mostly I tell rich men how to look sorry on television." She said it like a joke she'd told too often to find funny. "That suits you. You always knew how to make a story land." "And you always knew when one was lies." Priya smiled, but it didn't reach the grey eyes. "Remember the debate society? You destroyed that boy from Bristol. What was his name—" "I don't remember." "You do. You just don't want to." Priya leaned back. "You remember everything. That was the thing about you. You held onto every word anyone ever said." The silence that followed had weight. Outside, a bus hissed past, throwing light across the window. "How's Eva?" Priya asked. "She's well. London suits her better than me." Aurora paused. "She's the reason I'm here, actually. She got me out of Cardiff." "Got you out." Priya's voice softened, lost some of its polish. "I heard things. After. About you and Evan." Aurora's hand went still on the glass. The crescent scar on her wrist caught the lamplight, pale against her skin. "What did you hear?" "Enough that I should have called. And didn't." Priya looked down at her wine. "I told myself you'd reach out if you wanted help. That was the lie I needed. The truth is I was building something and I didn't want to look back at the people I'd left in the ditch." Aurora said nothing. She'd imagined this conversation, in the worst of those years—imagined the friends who'd vanished, the ones who'd watched Evan's hand close around her wrist at parties and called it love, called it passion, called it none of their business. Priya had been the sharpest of them. The one who saw everything. "You knew," Aurora said. Not a question. "I suspected." "You knew, Priya. You sat across from us at the Italian place on Cathedral Road and you watched him correct what I ordered and you said nothing." Priya's jaw tightened. "I was twenty-two. I thought that's what relationships looked like. Two people, one of them louder." "You were never that naive. That was always your trick—pretending not to see so you wouldn't have to act." The words landed flat and true, and Priya flinched. For a moment the polish cracked and Aurora saw underneath it, saw the girl who'd shared cheap cigarettes on the steps of the union building and talked about the people they'd become. They'd both meant it differently then. They'd both been wrong about everything. "You're right," Priya said. "I'm not going to pretend you aren't. I built a career on knowing what to look at and what to ignore. I just didn't know I'd been practising on my friends." Aurora turned her glass again. The whisky had gone warm. "I'm not angry," she said. "I used to be. Anger's exhausting. I let it go somewhere on the M4 with everything else." "That's worse, somehow. The not-angry." "Maybe." Priya reached into her coat and produced a card, then stopped, looking at it as though she'd surprised herself. "I was going to give you this. My number. Tell you we should get coffee, catch up, do the thing people do." She set it on the bar between them. "But I don't think you want to catch up. I think you want me to admit I left you alone and I'm sorry I did." "I left, Priya. Eventually I left. That's the part that matters." "It's the part that matters to you. It's not the part that matters to me." Priya finished her wine and stood, smoothing the expensive coat. "I think I needed to see you doing all right more than you needed to see me at all." Aurora looked at the card on the bar, the embossed name, the title that meant nothing and everything. She thought about the empty flat upstairs and the long years between then and now, the friends scattered, the girl who apologised to doors. "You don't know that I'm all right," she said. Priya paused, one hand on the back of the stool. "No. But you're here. You got here. That's more than I knew, an hour ago." She left the card. Aurora didn't pick it up, and didn't push it away either. Through the window she watched Priya step out under the green neon, raise her collar against the rain, and become another shape moving through the wet dark of Soho. Silas appeared, the bottle in his hand. "Another?" Aurora slid the empty glass toward him. "Yeah. Go on."
