Take the following details about characters/locations/... into account: <character name="Melanie"> Melanie is a 30-year old college student on a study abroad program. Born in Germany, she is fluent in German 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 German, 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

She responds troubled and shaken in German, and Hunter looks confused. They talk for a while, until Hunter gets a call and has to leave. Return the dialogue between Melanie and Hunter as a voice sheet: Melanie: "..." Hunter: "..."

Model response

Melanie: "Die Verschwundenen? Oh Gott, ja... gestern habe ich am Waldrand fotografiert und eine dunkle Gestalt gesehen, die plötzlich einfach fort war. Es hat mich so erschüttert, ich zittere noch!" Hunter: "Excuse me, miss. Detective Hunter. About those recent disappearances here in Alborn—did you see anything unusual?" Melanie: "Ich verstehe kein Wort! Nur Deutsch, bitte. Schauen Sie auf die Kamera—da sind die Fotos. Etwas stimmt nicht in diesem Ort!" Hunter: "Whoa, slow down. I don't speak a lick of German. English? Missing people—any idea where they went?" Melanie: "Nein, kein Englisch! Ich bin Melanie aus Deutschland, nur zum Studieren hier. Die Gestalt im Nebel... und dann war sie weg wie die anderen!" Hunter: "Look, this is no-nonsense work. If your photos show something, I need details. Point or something?" Melanie: "Helfen Sie mir doch! Es war unheimlich am Apfelfest-Gelände vorbei... ich kann es nicht erklären ohne Worte, die Sie verstehen!" Hunter: "Ah hell—my phone's ringing. Gotta take this call right now. Stay safe, I'll find a translator later. Leaving."
