Melanie: *[sitting at the cafe table, staring troubled at her camera screen, murmuring to herself]* Es war so dunkel... was war das? Hunter: Excuse me, miss. I'm Detective Hunter with the Alborn PD. Mind if I sit? I understand you were taking photos near the apple orchard last night during the festival. See anything unusual? Anyone who seemed out of place? Melanie: *[looks up shaken, eyes wide, voice trembling]* Ich... ich habe einen Mann gesehen. Er war dort, bei den Bäumen, und dann... einfach weg! Wie ein Geist! *[gestures frantically with her camera]* Hunter: *[confused frown, leaning in]* Uh... ma'am? Sorry, I didn't catch that. Do you speak English? English? Photos? Orchard? Melanie: *[shaking her head, more agitated, pointing at the camera screen]* Schauen Sie! Hier! Der Schatten... er hat jemanden mitgenommen! Hilfe, ich habe Angst! Hunter: *[scratching head, glancing at camera but not understanding]* Shadow? Who took who? Look, this is important—people have gone missing. Missing. *[mimes phone]* Can you call someone who speaks... German? Or write it down? Melanie: *[voice cracking, clutching camera]* Verschwunden! Alle verschwinden in dieser Stadt! Der Festival... Fluch! Ich muss weg, zurück nach Hause! Hunter: *[frustrated, pulling out notepad]* Okay, okay, slow down. Verdis... schwinden? *[butchers the word]* Wait—*[phone rings loudly]* Damn. Excuse me, I gotta take this. Stay here, alright? We'll get a translator. *[stands, answers phone]* Hunter here... yeah, on my way. Melanie: *[whispering to herself as he leaves]* Er versteht nicht... niemand versteht...
