Melanie: "Guten Tag. Mein Name ist Melanie. Ich mache hier ein Auslandssemester. Und ich spreche kein Englisch." Hunter: "Hi there, I'm Detective Hunter. I'm investigating the disappearances in Alborn. Have you seen anything unusual around town lately?" Melanie: "Es tut mir leid, ich verstehe wenig Englisch. Was ich sagen kann, kommt nur auf Deutsch." Hunter: "I don't speak German. Could you tell me what you saw in simple terms?" Melanie: "In der Nacht vor dem Apple Festival sah ich eine dunkle Gestalt am Flussufer. Sie bewegte sich leise hinter den Obstkisten, und dann war die Person einfach verschwunden." Hunter: "I still can't understand German well. If you can explain in simple terms, that would help." Melanie: "Es war mitten in der Nacht. Eine dunkle Gestalt stand am Flussufer, trug eine Kapuzenjacke, und verschwand im Nebel." Hunter: "I have to go now. I just got a call about an incident at the Apple Festival." Melanie: "Auf Wiedersehen."
