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

Model response

AI
Hunter: Excuse me, miss. I'm Detective Hunter with the Alborn PD. Mind if I ask you a few questions about the disappearance at the apple festival last night? Did you see anything unusual? Isabella: Io... io ho visto un uomo strano vicino all'orto dei meli. Stava litigando con la ragazza che è sparita. Era buio, ma la mia foto... oh Dio, era lui! Hunter: Uh... I'm sorry, what? Do you speak English? Foto? You took a picture? Can I see? Isabella: Non capisco! La polizia deve vedere questa foto! È importante! Lui l'ha trascinata via, verso il bosco! Aiuto! Hunter: Whoa, slow down. Bosco? That's... woods? Listen, if you have a photo of a suspect, that's huge. Can you show me your camera? Per favore? Show me? Isabella: Sì, sì! Guarda qui! Vedi? L'uomo con il cappotto nero. L'ha presa per il braccio, forte! Era terrorizzata! Hunter: Okay, black coat guy... got it. This could be our break in the case. Hang tight, I need to— *[phone rings]* Hunter: Hello? Yeah, dispatch—another one? On my way. Miss, stay here, I'll be right back with a translator! *[Hunter rushes off]*
