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.

It is known for its annual apple festival. </location>
User/Human

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

Isabella: "No... no, non voglio pensarci. È stato terribile. Ho visto solo ombre, e poi tutti correvano." Hunter: "I’m sorry—slow down. Did you see someone? Near the square?" Isabella: "La piazza... sì, ma era buio. C’era una donna, credo. Poi più niente. Solo paura." Hunter: "Okay. Woman. Did she leave with anyone?" Isabella: "Non lo so! Ho sentito un rumore, come un colpo, e il mio cuore... andava così veloce." Hunter: "You heard a shot?" Isabella: "Forse. Non sono sicura. Ero con la mia macchina fotografica... stavo guardando il cielo, i colori, e poi..." Hunter: "You had your camera with you. Did you take any photos?" Isabella: "Sì, sì... ma non voglio vedere. C’è qualcosa lì, qualcosa che non va." Hunter: "Something that doesn’t fit. Show me the camera." Isabella: "Qui... ma, per favore, guardi piano." Hunter: "I will. Just tell me if anyone followed you." Isabella: "Una macchina scura. E un uomo... alto. Non ho visto il viso." Hunter: "That helps. What direction did he go?" Isabella: "Verso la strada grande... credo. Non conosco i nomi qui." Hunter: "Right. I’ve got enough to start with—" Hunter: "Sorry, I need to take this. Stay here, and don’t leave with anyone." Isabella: "Aspetti—io... non capisco..." Hunter: "I know. I’ll be back."
