Model response

AI
Hunter: "Excuse me, miss. Detective Hunter. I'm investigating the mysterious disappearances here in Alborn. Have you seen anything unusual lately, maybe while photographing around the apple festival?" Isabella: "Oh... mi scusi, signore. Non parlo inglese, zero. Solo italiano. Cosa... cosa sta dicendo? Polizia? Scomparse? Sì, le scomparse misteriose qui in paese... sono scossa, terrorizzata. Ieri stavo scattando foto ai paesaggi autunnali vicino al festival delle mele e ho visto qualcosa di orribile. Una figura... poi sparita nel nulla. Non dormo da ieri, sono agitata." Hunter: "Whoa. I don't understand a single word of that. No Italian at all. Disappearances? Missing people? Apple festival? That camera of yours—photos?" Isabella: "Camera? Sì, la mia macchina fotografica! Fotografie di paesaggi. Il festival delle mele è bellissimo, ma ora c'è paura. Ho catturato qualcosa di inquietante nelle immagini. Sono una studentessa italiana in visita, studio all'estero, ma non so l'inglese e lei non l'italiano... come facciamo? Sono confusa e tremante." Hunter: "Language barrier's killing me. Look, if those landscape photos show anything tied to the missing folks, I need it. Can you show me the camera? Point to what you saw?" Isabella: "Mostrare le foto? Forse... ma quello che ho visto mi ha lasciata sconvolta. Una persona scomparsa proprio mentre scattavo. Alborn con i suoi tremila abitanti sembrava un posto tranquillo per il mio programma di studio... ora non so se restare. Non capisco le sue parole, solo indovino." Hunter: "Yeah, Alborn's small and quiet usually. These cases aren't. Your shaky reaction screams you witnessed something. Hell, I'd call a translator but—" Isabella: "Traduttore? Sì, forse serve. Non riesco a spiegare meglio. Sono nata in Italia, fluente solo nella mia lingua. Queste sparizioni stanno rovinando tutto. Per favore, non me ne vada... ho bisogno di aiuto, sono spaventata." Hunter: "This isn't working. Stay right there if you—hold on. Phone. ... Hunter here. What? Another disappearance confirmed? Damn it, I'm on my way now. ... Sorry, miss. Gotta run. Don't leave town." Isabella: "Che? Se ne va adesso? Aspetti! Le mie foto della sparizione... potrebbero essere importanti! Ma non ha capito niente. Oh mamma mia, restare sola con questo segreto... sono ancora più agitata."
