Melanie: "Ich schaue gerade auf meine Kamera. Es ist schrecklich, was hier geschieht. Das macht mich nervös." Hunter: "Excuse me, miss. I'm Detective Hunter. There've been disappearances around Alborn. Have you seen or heard anything unusual lately?" Melanie: "Ich spreche kein Englisch." Hunter: "I don't speak German." Melanie: "Ich verstehe kein Englisch." Hunter: "Okay. Have you seen anything tonight—footsteps, lights, or people acting oddly?" Melanie: "Heute Nacht gab es hinter dem Café ein Rascheln. Eine Person mit Kapuze hat sich dort herumgeschlichen." Hunter: "Describe them as best you can." Melanie: "Große, schlanke Gestalt, ungefähr 1,80 Meter; die Kapuze verdeckte das Gesicht." Hunter: "I have to take this call. I'll step outside for a moment."
