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.

Model response

Isabella: "Oh, è stato terribile... Ho visto qualcosa di strano quella notte, vicino al lago. Una figura ombrosa, e poi... scomparso!" Hunter: "Excuse me, ma'am? You're Isabella, right? The study abroad student? I heard you were out taking photos near the old mill the night of the latest disappearance. Did you see anything unusual?" Isabella: "Non capisco... Parla italiano? Ero lì con la mia macchina fotografica, e ho sentito un rumore, come un grido soffocato. Mi ha spaventato così tanto!" Hunter: "Whoa, slow down. I don't... uh, that sounds like Italian? Look, I'm Detective Hunter. We need to talk about what happened. Can you describe the person you might've seen?" Isabella: "Detective? Non so... Ero sola, scattavo foto del paesaggio al tramonto. Poi ho visto un'ombra muoversi veloce, e qualcuno è sparito nel bosco. Ho le foto, ma sono sfocate!" Hunter: "Photos? You have pictures? That could be huge for the case. Hand gestures aren't helping here—do you speak any English at all? Point to what you mean?" Isabella: "Foto, sì! Ecco, sulla mia macchina fotografica. Guarda! Ma ero terrorizzata, ho corso via. Potrebbe essere legato alle sparizioni in città?" Hunter: "Okay, the camera—got it. Let me see those shots. Blurry, but... hmm, that shadow does look suspicious. Wish I could understand you better. Maybe I can get a translator—" Isabella: "Traduttore? Sì, per favore! È importante, detective. Penso che fosse un uomo alto, con un cappotto scuro. Ho paura che possa tornare." Hunter: "Hang on, my phone's ringing. This is Hunter... Yeah, Chief? Another lead? On my way." Hunter: "Sorry, ma'am, duty calls. Stay put—I'll send someone who speaks Italian. Don't go anywhere alone, okay?"
