**Scene:** The cozy corner cafe in Alborn, MN buzzed softly with the chatter of locals enjoying their morning coffee. Isabella sat at a small wooden table near the window, her dark hair falling over one shoulder as she scrolled through the photos on her camera. The autumn light filtered in, highlighting the golden leaves outside—perfect for her landscape shots. She was still shaken from what she had witnessed two nights ago during the town’s apple festival. Hunter entered the cafe, his tall, imposing frame cutting through the relaxed atmosphere. The former Marine scanned the room with sharp eyes before spotting the young woman with the camera. He approached her table with purposeful steps. **Voice Sheet:** Isabella: "..." Hunter: "Excuse me, miss. I’m Detective Hunter with the Alborn Police. Mind if I sit down for a moment? I’m investigating the recent disappearance at the apple festival. Did you happen to see anything unusual that night?" Isabella: "Mi dispiace... non parlo inglese. Ero lì per fotografare le luci e le mele... ma ho visto qualcosa di strano vicino al frutteto. Una figura scura che trascinava qualcuno... ho paura che sia collegato alle sparizioni. Sono ancora scossa, non riesco a dormire." Hunter: "..." Isabella: "Per favore, mi capisce? Era un uomo alto, con un cappuccio... ho scattato una foto ma è sfocata. Ho troppa paura per mostrarla a chiunque." Hunter: "I... uh... I don’t speak Italian. Do you understand English at all? Any of this?" Isabella: "Non so cosa fare... ho solo la mia macchina fotografica. Se solo potessi spiegare..." Hunter: "This is... not helpful. Look, if you saw something, I need—" *Hunter’s phone suddenly rings. He glances at the screen, his expression tightening.* Hunter: "Damn it. I have to take this. We’ll... figure this out later. Stay safe, miss." *He gives her a frustrated but polite nod and quickly exits the cafe, answering the call as he goes.* Isabella: "Aspetta... per favore..." *(She watches him leave, clutching her camera tightly, the weight of what she saw still hanging over her like the crisp autumn air outside.)*
