# Cafe Scene: Voice Sheet Isabella: "Buongiorno. Scusa, posso aiutarti?" *(Good morning. Sorry, can I help you?)* Hunter: "Yeah, hi. Look, I'm Detective Hunter. I'm investigating some disappearances around town. Were you here last Tuesday night? Did you see anything unusual?" Isabella: "Mi dispiace, non capisco... inglese? Io parlo solo italiano." *(I'm sorry, I don't understand... English? I only speak Italian.)* Hunter: "English. I'm speaking English. Look, Tuesday night—do you remember Tuesday?" Isabella: "Ah... sì, sì, Tuesday... ma è stato terribile. Ho visto qualcosa di molto strano." *(Yes, yes, Tuesday... but it was terrible. I saw something very strange.)* Hunter: *scratches head, clearly frustrated* "I have no idea what you just said. Do you speak any English at all? Any English?" Isabella: "No, no English. Mi scusi, molto difficile. I have... camera. Foto. Pictures?" *(No English. I'm sorry, very difficult. I have... camera. Photos. Pictures?)* Hunter: "Photos? You took photos? Of what?" Isabella: *voice trembling, hands shaking as she scrolls through her camera* "Quella notte... quella ragazza... è sparita. Non so dove. Era così strano, così spaventoso." *(That night... that girl... she disappeared. I don't know where. It was so strange, so frightening.)* Hunter: "I wish I understood you. Can you show me the photos at least?" Isabella: *turns camera toward him, pointing at images with a distressed expression* "Guarda! Guarda qui! C'era qualcuno... qualcuno che non dovrebbe essere lì!" *(Look! Look here! There was someone... someone who shouldn't be there!)* Hunter: *studies the camera screen intently* "Okay, okay, I see something. I'm going to need you to come down to the station. We'll figure out how to communicate." Isabella: "Stazione? Polizia?" *(Station? Police?)* Hunter: "Yes, police. We need to—" *Hunter's phone buzzes loudly. He checks it, his expression darkens.* Hunter: "Damn it. I'm sorry, I have to take this. Don't move." *He steps away, phone to his ear.* Hunter: *returning, speaking quickly* "Listen, I have to go. Another situation. But you—stay here. Stay in town. Don't leave." Isabella: "Aspetta! Detective, per favore! Ho paura! I'm... scared?" *(Wait! Detective, please! I'm afraid!)* Hunter: "I get it. Just... stay safe. Lock your doors tonight. We'll talk tomorrow." *He rushes out of the cafe, leaving Isabella alone with her camera and her troubled thoughts.* --- **END SCENE**
