Model response

AI
Isabella: *(murmuring to herself, scrolling through her camera)* "Non riesco a credere... era proprio lì, in questa foto..." Hunter: "Excuse me, miss. Mind if I ask you a few questions? I'm Detective Hunter, looking into some disappearances around town." Isabella: *(startled, looking up)* "Oh! Mi scusi, non l'avevo vista arrivare. Lei è... un poliziotto?" Hunter: "I'll take that as a yes. You were here in the square two nights ago, weren't you? During the festival setup?" Isabella: *(growing agitated, gesturing at her camera)* "Sì, sì! Ero qui! Stavo fotografando il tramonto, ma poi... ho visto qualcosa di terribile. Guardi! Guardi questa foto!" Hunter: *(frowning, leaning in)* "Slow down. I don't... I have no idea what you're saying. Do you speak any English at all?" Isabella: *(voice trembling, near tears)* "Non capisce? C'era un uomo... e poi è sparito! Semplicemente sparito! Ho ancora le mani che tremano, lo vede?" Hunter: "Hey, hey—easy now. You're shaking. Something scared you, didn't it?" *(softening)* "I wish I could understand you." Isabella: *(showing him the camera screen insistently)* "Qui! La prova è qui! Per favore, deve credermi, ho visto tutto con i miei occhi!" Hunter: *(squinting at the screen)* "That's... a photo of the square. Is there something in it? Can you—" *(Hunter's phone rings sharply. He holds up a finger.)* Hunter: "Hold that thought. Hunter here." *(pause, expression hardening)* "Another one? Where? ...Got it. I'm on my way." Isabella: *(desperate, reaching out)* "No, aspetti! Non se ne vada! Devo mostrarle—" Hunter: *(standing, pocketing the phone)* "I'm sorry, miss. I gotta go—there's been another disappearance." *(pointing at her, then the café)* "Stay. Here. I'll bring someone who speaks Italian. Don't go anywhere, okay?" Isabella: *(watching him hurry off, clutching her camera)* "...Ma la foto... la risposta è proprio qui."
