# Voice Sheet: Café Encounter **Setting: A small café on Main Street, Alborn, MN. Melanie sits alone at a window table, scrolling through photos on her camera.** --- Hunter: "Excuse me, miss? Mind if I sit down for a moment?" Melanie: "Oh... ja, bitte." *gestures to the chair, looking uncertain* Hunter: "I'm Detective Hunter. I'm investigating some strange occurrences around town. Were you by any chance near Miller's Creek yesterday evening?" Melanie: "Ich... ich verstehe nicht gut. Englisch ist schwer für mich." *shakes her head apologetically* Hunter: "I'm sorry, I don't... are you saying you don't speak English?" Melanie: "Ja, ja. Ich habe etwas gesehen. Es war schrecklich. Ein Mann... er ist einfach verschwunden. Ins Nichts!" *her voice trembles, hands gripping the camera* Hunter: "Whoa, okay. I can see you're upset. I wish I understood what you were saying." Melanie: "Er war da, und dann—puff—weg. Ich habe Fotos gemacht, aber ich weiß nicht, ob sie etwas zeigen." *taps her camera urgently* Hunter: "Photos? Are you trying to show me something on your camera?" Melanie: "Ja! Fotos! Schauen Sie!" *turns the camera screen toward him* Hunter: "I see... that's the old bridge. And that blur there—" *Hunter's phone rings* Hunter: "Hunter here. ...Yeah. ...Right now? Understood." *stands up* "I'm sorry, I have to go. But listen—" *points at her, then at the café* "Stay. Here. I'll find someone who can translate. Okay?" Melanie: "Bleiben? Hier warten?" *points down at the table* Hunter: "Yes. Wait. Please." Melanie: "Ja. Ich warte. Bitte kommen Sie zurück. Ich habe Angst." Hunter: *pauses at her tone, recognizing fear even without words* "I'll be back. I promise." --- *Hunter exits. Melanie clutches her camera, staring at the last photo on the screen—a figure mid-vanish in a wash of impossible light.*
