# Voice Sheet: Cafe Encounter **Isabella:** *(looking up from her camera, eyes wide with distress)* "Oh, grazie a Dio... scusi, scusi. Ho visto qualcosa di terribile questa mattina. Vicino al bosco, dietro la chiesa. Non so cosa sia successo, ma... *(voice trembling)* ...non era giusto." **Hunter:** *(confused, furrowing his brow)* "Ma'am, I'm Detective Hunter. I need to ask you some questions about what you saw yesterday near the town square." **Isabella:** *(wringing her hands, speaking rapidly in Italian)* "Non capisco. Non... non English. Parla italiano? Per favore, qualcuno che parla italiano?" **Hunter:** *(sighing, speaking slowly and loudly as if volume will help)* "The... disappearances. You see anything strange?" **Isabella:** *(shaking her head, holding up her camera desperately)* "Scomparse? Cosa significa? Io... *(frustrated, pointing to herself)* ...Italia. Solo italiano. Non—not English." **Hunter:** *(rubbing his temples, pulling out a small notebook)* "Look, I don't know what you're saying, but I need you to—" **Isabella:** *(interrupting, still distressed)* "C'era una persona che non era... normale. Nel bosco, stamattina presto. Ho scattato delle foto ma poi... poi ho avuto paura e sono scappata." **Hunter:** *(staring blankly at her)* "...Right." *(An awkward silence falls between them. Hunter attempts a few more questions, getting only more Italian responses. He pulls out his phone to try to find a translation app.)* **Isabella:** *(quietly, almost to herself)* "Nessuno mi capisce qui. Nessuno." **Hunter:** *(phone buzzes loudly; he checks it, his expression hardening)* "Hold that thought." *(His phone rings. Hunter answers immediately, his voice shifting into professional mode.)* **Hunter:** "Hunter here. Yeah? ...When? ...I'm on my way." *(He ends the call and looks back at Isabella with genuine apology in his eyes, though his jaw is set.)* **Hunter:** "I gotta go. There's been another one. Don't leave town—and don't go near those woods alone. Stay somewhere public." **Isabella:** *(not understanding but sensing the urgency)* "Scusi? Detective? Aspetta! Per favore!" **Hunter:** *(already standing, pulling out a business card and placing it on the table)* "Stay safe." *(He leaves quickly, and Isabella is left alone with her camera, still trembling, her photographs potentially holding crucial answers that neither of them can yet communicate.)*
