Melanie: "Oh Gott, es war so schrecklich! Ich habe mit meiner Kamera fotografiert, als der Mann plötzlich verschwand... ich bin total durchgeschüttelt und habe solche Angst!" Hunter: "Excuse me, miss. I'm Detective Hunter. I need to ask you about the strange event that happened near the orchard last night. Did you see anything unusual?" Melanie: "Nein, kein Englisch! Nur Deutsch! Es war wie ein Schatten... die Leute verschwinden einfach. Ich verstehe das nicht, und ich habe Fotos gemacht, aber ich bin so aufgewühlt!" Hunter: "I... don't understand a word of that. German? Do you speak any English at all? English? Did you witness the disappearance?" Melanie: "Verschwinden, ja! Hilfe! Ich habe solche Angst, dass ich die Nächste sein könnte. Bitte, schauen Sie sich meine Bilder an... ich bin nicht von hier und weiß nicht, was ich tun soll!" Hunter: "This language barrier is making this impossible. You look shaken, but I can't get anything useful. Are you saying you have evidence on your camera?" Melanie: "Die Kamera... ja, schreckliche Dinge! Ich bin so durcheinander, alles ist falsch in dieser Stadt. Warum verstehen Sie mich nicht?" Hunter: "Alright, this isn't going anywhere. Sorry, but I've just gotten a call from the station. I have to leave immediately. We'll figure out a translator next time." Melanie: "Warten Sie! Bitte gehen Sie nicht... ich brauche Hilfe!"
