Take the following details about characters/locations/... into account: <character name="Isabella"> Isabella is a 30-year old college student on a study abroad program. 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
Write the following scene: Isabella is sitting at a cafe, looking at her camera. Hunter approaches her and asks her about a recent event in the town. She responds troubled and shaken in Italian, and Hunter looks confused. They talk for a while, until Hunter gets a call and has to leave. Return the dialogue between Isabella and Hunter as a voice sheet: Isabella: "..." Hunter: "..."

Model response

AI
Isabella: *sits at the cafe table, staring troubled at her camera screen, murmuring to herself* Ho visto... non può essere... Hunter: Excuse me, miss. I saw you with that camera—were you at the apple festival last night? Taking pictures near the orchard? Isabella: *shaken, eyes wide, speaking rapidly in Italian* Sì! Ho fotografato tutto! C'era un uomo... alto, con un cappello nero... e poi è sparito! Qualcuno l'ha preso! Ho paura! Hunter: *confused frown* Uh... sorry, I don't speak Italian. English? Did you see something by the orchard? A man? *gestures photographing* Isabella: *frantic, pointing at camera screen* No English! Guarda! *shoves camera toward him* Uomo sparito! Polizia! Aiuto! Hunter: Okay, okay, slow down. This photo... a guy in a hat? He vanished? Like the others who've gone missing? *squints at screen* Can you describe him more? Tall guy? Isabella: *nodding vigorously, voice trembling* Sì, alto! Cappello nero, occhi cattivi... notte, ombra... *mimes dragging motion* Trascinato via! Hunter: Dragged away? Damn, that's the break we need. Stay here—I'll get an interpreter. What's your name? *Hunter's phone rings loudly* Hunter: Hold that thought... *answers* Hunter here. Yeah? Another one? On my way. *stands quickly* Don't go anywhere, miss—we need to talk more. Isabella: *calls after him, distressed* Aspetta! Per favore!
