Here's the voice sheet for the scene: **Melanie:** "Oh, mein Gott! Es war so schrecklich. Ich habe es gesehen… es war so plötzlich. Der Schrecken… Ich kann es nicht vergessen." (Oh, my God! It was so terrible. I saw it… it was so sudden. The terror… I can't forget it.) **Hunter:** "Excuse me? Ma'am, are you alright? I'm Detective Hunter. I'm investigating the disappearances. I need to ask you about what you might have seen around town recently, specifically anything unusual in the last few days." **Melanie:** (Shaking her head, her eyes wide with a lingering fear) "Ich verstehe nicht. Englisch? Ich spreche kein Englisch. Nur Deutsch." (I don't understand. English? I don't speak English. Only German.) **Hunter:** (Frowning, a hint of frustration in his voice) "Look, I… I need to ask you some questions. About… the recent events. The missing people. Did you see anything? Anything at all?" (He gestures vaguely around the cafe, then points a finger in the direction of the town square, hoping she'll understand the implication.) **Melanie:** (Her hands clutched tightly around her camera, she gestures with it towards an unseen place outside, her voice trembling) "Ja. Ich war dort. Mit meiner Kamera. Ich wollte die Vögel fotografieren. Und dann… dann geschah es. Es verschwand. Einfach so." (Yes. I was there. With my camera. I wanted to photograph the birds. And then… then it happened. It disappeared. Just like that.) **Hunter:** (Completely lost, he rubs the back of his neck) "Disappeared? What disappeared? A person? An animal? Look, if you saw something, anything that seemed out of place, no matter how small, it could be important." **Melanie:** (Her voice barely above a whisper, full of a deep, unsettling sadness) "Ich weiß es nicht. Es war… ein Schatten. Ein großes, schnelles Ding. Es war fort. So schnell. Und dann… dann war nichts mehr da." (I don't know. It was… a shadow. A big, fast thing. It was gone. So fast. And then… then there was nothing left.) **Hunter:** (He leans in slightly, trying to catch any visual cues. He points to his eyes, then to hers, then back to his notebook.) "Can you… describe it? Gestures? Anything?" **Melanie:** (She shakes her head again, unable to find the words in a language he would understand, her gaze distant as if replaying the disturbing memory.) "Nein. Es war zu schnell. Ein Blitz. Und diese Stille danach… die Stille war das Schlimmste." (No. It was too fast. A flash. And that silence afterwards… the silence was the worst.) **Hunter:** (He sighs, clearly at a dead end without a translator. Just then, his phone vibrates loudly in his pocket. He pulls it out and looks at the caller ID, his expression immediately turning serious.) "Hold on. I gotta take this." (He holds up a finger, then answers the phone, his voice dropping to a terse, professional tone.) "Hunter here. What do you got? ... Alright. I'm on my way." (He snaps his phone shut, his eyes meeting Melanie's for a brief, apologetic moment.) "I’m sorry, ma’am, I have to go. Something just came up. I’ll… I’ll be back. Or I’ll send someone. Someone who speaks German." (He gives a quick, curt nod and then strides quickly out of the cafe, leaving Melanie alone, still clutching her camera, the troubling memory evident in her eyes.)
