Model response

AI
Hunter: "Excuse me, miss. I'm Detective Hunter. I'm investigating the series of mysterious disappearances here in Alborn. Have you noticed anything unusual recently? Maybe while you were taking photos?" Melanie: "Guten Tag... Oh Gott, die Verschwundenen. Ja, ich habe etwas gesehen. Es hat mich so erschüttert. Gestern, beim Fotografieren der Landschaft in der Nähe des Apfelhains, da war plötzlich eine Person... und dann war sie fort! Ich bin so verstört und weiß nicht, was ich tun soll." Hunter: "Whoa, German? I don't speak a word of it. Lady, English? Disappearances? Photos? Camera?" Melanie: "Nein, ich spreche kein Englisch. Bitte, Detektiv... Sie sind der Detektiv? Helfen Sie mir. Diese Ereignisse sind unheimlich. Die Leute hier reden vom Apfel-Festival, aber ich habe Angst. Schauen Sie meine Fotos an, vielleicht ist etwas darauf." Hunter: "Your photos? Yeah, let's see. Oh hell—my phone. Hello? Hunter here. Another disappearance? Understood, I'm on my way. Sorry, miss, duty calls. I'll find a translator and circle back. Stay safe."
