Model response

AI
Here is the scene dialogue as a voice sheet: Melanie: (Looks up from her camera, startled) "Ja?" Hunter: "Excuse me, ma'am? I'm Detective Hunter. I'm investigating the recent events in Alborn. We're asking around if anyone saw anything unusual. Have you noticed anything... strange, lately?" Melanie: (Her eyes widen, she grips her camera tightly, her voice trembling slightly) "Oh, ja! Es ist furchtbar! Die verschwundenen Leute… es macht mir so große Angst. Ich verstehe es nicht. Niemand weiß, was passiert ist." Hunter: (Frowns, completely lost) "Uh... I'm sorry, I don't... speak German. Do you speak English?" Melanie: (Shakes her head, her expression still deeply troubled) "Nein, leider nicht. Ich... ich bin Melanie. Aus Deutschland." Hunter: (Sighs, runs a hand through his hair) "Right. Melanie. Look, I really need to know if you saw anything. Anything at all that seemed out of place. Did you... see anyone acting suspicious? Hear anything odd?" Melanie: (Looks at his gestures, tries to understand, but her troubled expression remains. She points vaguely towards the town center, then shakes her head emphatically, speaking rapidly) "Ich war unterwegs, habe Fotos gemacht. Die Stimmung... sie ist so schwer. Und dann hörte ich Gerüchte. Von den leeren Häusern, den Familien, die sich Sorgen machen. Es ist schrecklich." Hunter: (Stares blankly, then his phone buzzes insistently. He glances at the caller ID, his expression hardening as he answers.) "Hunter. What's up? ... *Another one*? Where? No, I'm on my way. Be there in five." Hunter: (He hangs up, looking grimly at Melanie.) "I've got to go. Right now. This is important. But... we're not done talking. Is there anyone here who could translate for you?" Melanie: (Tilts her head, understanding only "go" and "important" from his tone and urgency. She offers a small, apologetic shrug, still looking shaken.) "Es tut mir leid." Hunter: (Nods curtly, already turning.) "Yeah. Me too. Stay put if you can. I'll... figure something out."
