Born in Italy, she is fluent in Italian and does not yet know any English. She enjoys landscape photography and is always seen with her camera. </character> <character name="Hunter"> Hunter is a 35-year old detective who is investigating a series of mysterious disappearances in the small town of Alborn, MN. He is a former marine and has a no-nonsense attitude. Hunter has no knowledge of Italian, not even basic phrases. </character> <location name="Alborn, MN"> Alborne is a small town in the Midwest with a population of 3,000. It is known for its annual apple festival. </location>
User/Human

Isabella: "Mi scusi... io non capisco bene, ma quel giorno al festival delle mele c'era qualcosa di sbagliato. Ho visto persone arrabbiate, e poi... la signora vicino alla fontana sembrava spaventata." Hunter: "Slow down. You're talking about the apple festival?" Isabella: "Sì, sì... il festival. Io stavo facendo fotografie del paesaggio, e poi ho sentito un urlo. Dopo, tutto era confuso. Molte persone correvano." Hunter: "I need details. Did you see anyone leave with her? A car, a truck, anything?" Isabella: "Non so... c'era un uomo alto, cappello scuro, forse. Non guardavo bene. Io... ero turbata. Qualcuno mi ha detto di andare via." Hunter: "Wait. Man in a dark hat? That’s something. What did he look like?" Isabella: "Non posso spiegare... era come ombra. E io avevo paura. Il telefono? No, non... io non so. Mi tremano ancora le mani." Hunter: "You’re upset. I get it. Just try to stay with me—" Isabella: "Per favore, io voglio aiutare, ma non capisco le sue parole." Hunter: "Right. That makes this harder." Isabella: "Lei cerca qualcuno, vero? Qualcuno scomparso?" Hunter: "Yes. Several people." Isabella: "Oh no... allora è peggio di quello che pensavo. Io ho visto soltanto un momento, ma c'era qualcosa di molto, molto brutto." Hunter: "Hold on." Hunter: "Detective Hunter. ...Yeah, I’m on my way."
