Melanie: Es ist schrecklich hier. Ich bin nervös. Ich kann kein Englisch. Hunter: I don't understand German. Melanie: Ich kann nur Deutsch sprechen. Bitte holen Sie jemanden, der übersetzen kann. Hunter: Then tell me in German what you saw. Melanie: Letzte Nacht hörte ich Schritte vor dem Café. Heute Morgen fehlen zwei Leute. Hunter: Two people missing? What exactly did you hear? Melanie: Ich hörte langsame Schritte, als ob sich jemand verstecken wollte. Hunter: I still can't understand. Melanie: Vielleicht kann eine Übersetzerin helfen. Hunter: I have to take this call. Hunter: I have to go now. We'll talk again later.
