# Scene: Alborn Cafe - Voice Sheet Melanie: *looks up from her camera, startled* "Ja? Kann ich dir helfen?" Hunter: *pulls up a chair, badge visible* "I'm Detective Hunter. I need to ask you some questions about what you saw last night near the old apple orchard." Melanie: *clutches her camera tighter, eyes wide* "Ich... ich verstehe nicht. English? Nein, nein... Deutsch nur." Hunter: *narrows eyes, clearly frustrated* "English. Do you speak English?" Melanie: *shakes her head, speaking rapidly in German* "Nein, nein English. Ich bin aus Deutschland. Ich spreche nur Deutsch. Und... und letzte Nacht war schrecklich. Schrecklich!" Hunter: *leans back, rubbing his temples* "Great. Just great." *pulls out his phone to search for a translator* "Listen, I don't understand a word you're saying, but I need to know—" Melanie: *interrupts, distressed German pouring out* "Es war so dunkel! Ich habe nur Fotos machen wollen und dann... dann ist jemand einfach verschwunden! Einfach weg!" Hunter: *watches her gestures intently, trying to piece together her meaning* "Okay, okay... slow down. Disappear? Someone disappear?" Melanie: *nods frantically, pointing toward her camera screen* "Ja, ja! Verschwunden! Meine Kamera... meine Kamera hat alles gesehen, aber ich..." *Hunter's phone suddenly buzzes loudly. He glances at it, jaw tightening.* Hunter: *standing abruptly* "I'm sorry, I—there's an emergency. Another disappearance reported on Maple Street." *pulls out a notepad, frustrated* "Can you... do you have anyone who speaks German? Anyone?" Melanie: *looks at him helplessly, still visibly shaken* "Ich weiß nicht, was du fragst... Bitte, die Bilder... die Bilder sind wichtig!" Hunter: *sighs heavily, heading toward the door* "Don't leave town. And keep that camera safe—I'll be back with someone who can actually understand you." *pauses at the door* "This is going to be a long investigation." Melanie: *calls after him in German, her voice trembling* "Warte! Es ist gefährlich! Du musst mir zuhören!" *Hunter exits without understanding a word, leaving Melanie alone with her camera and her troubled secrets.*
