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.

Model response

AI
Isabella: "Mi dispiace, non parlo inglese. Sono Isabella, una studentessa straniera. Ieri sera ho visto una figura vicino al mercato mentre scattavo foto. Sono molto spaventata." Hunter: "I don't understand Italian. Please tell me what you saw in English." Isabella: "La scomparsa di una ragazza ha agitato la città. Ho visto una figura incappucciata che si muoveva tra le ombre." Hunter: "A hooded figure near the market? Describe it in English." Isabella: "La figura aveva una giacca scura, camminava lentamente, e mi fissò." Hunter: "If you have a photo, it could help. Do you have it with you?" Isabella: "Sì, ho scattato una foto della figura." Hunter: "Let me see the photo. Where is it?" Isabella: "Nella mia borsa, vicino al cuore." Hunter: "I have to take a call. There's an urgent lead I need to check." Hunter: "I have to leave now. We'll talk more when I get back." Isabella: "Va bene."
