AI
Isabella: *(murmuring to herself, scrolling through photos)* "Non è possibile... ero proprio lì. L'ho visto con i miei occhi..." Hunter: "Excuse me, miss? Sorry to bother you. I'm Detective Hunter, Alborn PD. Mind if I ask you a few questions?" Isabella: *(looking up, startled)* "Oh—mi scusi, non... non capisco bene. Lei è un poliziotto?" Hunter: "A detective, yeah. I'm looking into what happened by the old mill last night. You were in that area, weren't you? I recognize the camera." Isabella: *(clutching her camera to her chest)* "Il mulino... sì, ero là. Stavo fotografando il tramonto, e poi... ho visto qualcosa. Qualcuno. È sparito nel nulla!" Hunter: *(frowning, holding up a hand)* "Whoa, slow down. I'm not following any of that. You speak any English at all?" Isabella: "Inglese? No, no... mi dispiace. Sono appena arrivata. Studio qui, ma la lingua... è troppo difficile." Hunter: "Italian. Great. Just my luck." *(rubbing the back of his neck)* "Okay. Let's try this differently. The mill?" *(pointing vaguely west)* "You. There. Last night?" Isabella: *(nodding rapidly)* "Sì! Sì, il mulino. Ieri sera. C'era una persona, e poi—" *(she makes a vanishing gesture with her hands)* "—puff. Sparita. Ho avuto tanta paura." Hunter: *(watching her hands)* "You saw someone disappear. Is that what you're telling me? Were you scared? You look pretty shaken up." Isabella: *(eyes glistening)* "Ho ancora il cuore che batte forte. Non riesco a dormire. Ho delle foto, vede?" *(turning the camera screen toward him)* "Guardi. Guardi qui!" Hunter: *(leaning in, squinting at the screen)* "Wait—you got pictures? Let me see that. That shadow there, by the door... that's not nothing." *(reaching for the camera)* "Can I—?" Isabella: *(pulling it back gently, then relenting)* "Va bene, va bene. Ma per favore, è importante. Forse quello che ho visto è collegato a quelle persone scomparse." Hunter: "I don't know what you just said, but the look on your face tells me it matters. Listen, I need to get these photos to the station, maybe find someone who can translate—" *(Hunter's phone buzzes loudly. He answers.)* Hunter: "Hunter. ...What? When? ...No, don't touch anything, I'm on my way." *(standing abruptly)* "Look, miss, I gotta go. Something just came up." *(pointing at her, then miming a phone)* "Stay. Here. I'll come back. Okay? Don't move." Isabella: *(confused, half-rising)* "Aspetti—dove va? Detective! Le mie foto—" Hunter: *(already backing away)* "I'll find a translator, I promise. Just—stay put." *(under his breath)* "...assuming I can find anyone in this town who speaks Italian." Isabella: *(sinking back into her chair, hugging the camera, whispering)* "...Resta calma, Isabella. Tornerà. Deve tornare."
