Here's the voice sheet for the scene: Melanie: (humming softly, the click of her camera buttons audible) Hunter: (approaching, a slight hesitation in his step) "Excuse me, miss? Do you mind if I ask you a few questions about something that happened in town recently?" Melanie: (looks up, startled, her eyes wide with a flicker of something troubled. She clutches her camera tighter. In a shaky voice) "Entschuldigen Sie, ich verstehe nicht." (I'm sorry, I don't understand.) Hunter: (brow furrowed, a hint of frustration beginning to show) "I'm Detective Hunter. I'm investigating a few disappearances. Did you... see anything unusual around here the other night? Maybe near the old orchard?" Melanie: (her lower lip trembles. She shakes her head slowly, then speaks in a rush, her German tumbling out quickly, filled with fear and confusion) "Nichts Gutes! Es war dunkel und beängstigend. Ich habe… ich habe Geräusche gehört. Seltsame Geräusche. Und dann war es einfach… weg. Alles weg." (Nothing good! It was dark and scary. I… I heard noises. Strange noises. And then it was just… gone. Everything gone.) Hunter: (watching her intently, though the words are a complete jumble to him. He tries a different tack, speaking slowly and clearly) "Ma'am, I really need to know what you saw. There have been people vanishing. People disappearing. Do you understand 'disappearing'?" Melanie: (her eyes dart around, as if looking for an escape. She shivers, wrapping her arms around herself. Her voice is a little louder, more insistent, desperate to be understood) "Ich habe nur versucht, die Sterne zu fotografieren! Und dann diese… diese Schatten. Bewegten sich so schnell. Und die Kälte. Es war so kalt, obwohl es September ist. Ich weiß nicht, was ich gesehen habe, aber es war nicht normal! Es war furchtbar!" (I was just trying to photograph the stars! And then these… these shadows. Moving so fast. And the cold. It was so cold, even though it's September. I don't know what I saw, but it wasn't normal! It was terrible!) Hunter: (runs a hand through his hair, clearly at a loss. He glances around the cafe, hoping for an interpreter, but it's largely empty. He tries one more time, pointing roughly in the direction of the town square) "The festival… the apple festival. Was there anything… unusual related to the festival? Did you see anyone, any people… leave?" Melanie: (shakes her head vehemently, tears welling in her eyes. She gestures vaguely towards the edges of town) "Nicht das Fest. Es war draußen. Weiter draußen. Wo es still war. Und die Stille danach war noch schlimmer als die Geräusche." (Not the festival. It was outside. Further outside. Where it was quiet. And the silence afterward was even worse than the noises.) Hunter: (sighs, pulling out his phone. He clearly doesn't want to leave, but the vibrating in his hand is insistent. He holds up a finger, a silent 'one moment') "Hold on a second." (He answers his phone, his voice dropping to a low, serious tone) "Hunter here. What's up? ... *Another one*? ... Alright, I'm on my way." (He looks back at Melanie, a frustrated apology in his eyes) "Look, I have to go. Something just came up. I'm going to find someone who can translate. Don't go anywhere, okay? I'll be back." Melanie: (stares at him, uncomprehending, her body still trembling slightly. She watches him turn and stride away, leaving her alone with her camera and her fear.)
