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
Hunter: "Excuse me, miss. Detective Hunter, Alborn PD. Investigating the recent disappearances. You see anything odd around the apple festival or the woods?" Melanie: "Entschuldigung? Ich... ich verstehe Sie nicht. Bitte, ich spreche nur Deutsch. Was ist los? Es ist so schrecklich..." Hunter: "German only? Figures. Look, people are vanishing. That camera of yours—snap any photos that looked wrong? Out near the orchards?" Melanie: "Meine Kamera? Ja, ich mache Landschaftsfotos. Aber gestern... oh Gott, ich habe jemanden gesehen, der weglief und dann... nichts mehr. Es macht mir solche Angst! Bitte helfen Sie mir!" Hunter: "You're shaking pretty hard. Easy. Whatever spooked you, I need the details. Point it out on the screen if you can." Melanie: "Hier, schauen Sie... dieses Foto... die Frau vom Festival... sie ist weg! Einfach verschwunden! Warum versteht niemand mich? Ich habe solche Panik..." Hunter: "Festival shots, got it. Might be useful later. Hold on—phone's going. ... Hunter. Yeah, another call-out? Understood. Moving now. Sorry, miss, I have to leave. Don't go far; I'll get a translator out here."
