Model response

AI
Hunter: "Miss? I'm Detective Hunter. I need to ask you about what happened in town last night." Isabella: "Io... io non volevo vedere quella cosa. Era tutto così buio, e poi quella persona è sparita." Hunter: "I'm sorry, I don't understand. Did you see someone? At the festival? Near Main Street?" Isabella: "Sì, sì, una persona. Vicino agli alberi. Ho sentito un rumore, poi un grido... e dopo, niente." Hunter: "Trees? A scream? Okay, slow down. Are you saying someone was taken?" Isabella: "Non lo so! Sembrava spaventato. Io stavo facendo fotografie, e poi... ho visto un'ombra." Hunter: "Photographs? You took pictures?" Isabella: "La mia macchina fotografica, sì. Ma le mie mani tremavano. Non so se si vede qualcosa." Hunter: "Your camera might help, but I can't understand what you're telling me." Isabella: "Mi dispiace, non parlo inglese. Sto cercando di spiegare, ma... è stato terribile." Hunter: "Right. Okay. You don't speak English, and I don't speak... Italian, I guess. Great." Isabella: "C'era qualcuno dietro il chiosco delle mele. Ne sono quasi sicura. Poi quella donna non c'era più." Hunter: "Behind the apple stand? A woman disappeared?" Isabella: "Sì! Sì, una donna! Finalmente—sì. Lei era lì, e un attimo dopo, sparita." Hunter: "Okay. That's something. Stay here. I may need that camera." Hunter: "Hunter speaking... What? Another one? Where?... I'm on my way." Hunter: "I have to go. Stay here, don't leave town, and keep that camera safe." Isabella: "Aspetti! Non capisce—io ho paura."
