Melanie: "Oh Gott, es war so furchtbar... Ich habe gesehen, wie dieser Mann einfach verschwunden ist, bei dem Apfelfestival. Als ob er in Luft aufgelöst wäre!" Hunter: "Excuse me, ma'am? I'm Detective Hunter. I noticed your camera there—did you happen to see anything unusual at the apple festival last night? We're looking into a missing person." Melanie: "Ich verstehe nicht... Was sagen Sie? Der Mann, er hatte einen roten Mantel, und dann... poof! Weg! Ich habe Fotos gemacht, aber ich bin so erschüttert!" Hunter: "Whoa, slow down. Is that... German? I don't speak German. Uh, do you speak English? Englisch? Can you show me the photos on your camera?" Melanie: "Englisch? Nein, nein... Ich spreche nur Deutsch. Die Fotos? Hier, schauen Sie! Sehen Sie den Mann? Und dann ist er weg. Es war unheimlich!" Hunter: "Okay, photos—yeah, I get that. Let me see... Huh, that's interesting. This guy in the red coat? You saw him vanish? Wait, vanish? Like, poof? I have no idea what you're saying, but these pics might help. Can I borrow the camera?" Melanie: "Borrow? Was? Nein, das ist meine Kamera! Aber ja, schauen Sie nur. Ich bin hier auf Austausch, und das ist alles so verrückt. Rufen Sie die Polizei?" Hunter: "Police? That's me, I'm the detective. Look, I think we're onto something here. Hang on, maybe I can get a translator app on my phone..." Melanie: "Translator? Ach, Sie verstehen nichts. Der Mann, er schrie kurz auf, und dann war da dieser Schatten... Ich habe Angst!" Hunter: "Shadow? Wait, you're pointing at the photo—shadow? Okay, this is getting weird. Just stay calm, I'll figure this out." *(Hunter's phone rings.)* Hunter: "Hold on, that's my phone. Detective Hunter speaking... What? Another disappearance? I'm on my way. Sorry, ma'am, I gotta go—stay here, okay? Don't go anywhere!" Melanie: "Gehen? Aber... warten Sie! Was soll ich tun?"
