# Voice Sheet: Cafe Scene **Isabella:** *[looking at photos on camera, muttering to herself]* "Che strano... non capisco cosa sia successo..." **Hunter:** "Excuse me, miss. I'm Detective Hunter with the local police. Mind if I ask you a few questions?" **Isabella:** *[looks up startled, eyes wide]* "Oh! Mi dispiace, io... io non parlo inglese molto bene. Ehm..." **Hunter:** "I'm investigating the disappearance that happened near the town square yesterday. Were you in the area?" **Isabella:** *[visibly shaken, gripping her camera tighter]* "Sì, sì! Ero lì! Ho visto... Madonna, era terribile! C'era una donna, e poi... e poi è semplicemente sparita! Non so come spiegare!" **Hunter:** *[frowning]* "I... I'm sorry, I don't understand. Do you speak English?" **Isabella:** *[frustrated, speaking rapidly]* "Non capisce? La donna! Ho delle foto, guarda!" *[frantically scrolling through camera]* "Era proprio qui, e poi... niente! Scomparsa! Come è possibile?" **Hunter:** "Okay, slow down. I can see you're upset, but I can't understand what you're saying. English? Habla español?" **Isabella:** *[tears forming]* "Io... io studio qui, ma il mio inglese... Dio, perché non mi capisce? Ho visto qualcosa di importante! Devo dirgli!" **Hunter:** *[pulling out notepad, speaking slowly]* "Let me try this. Your... name?" **Isabella:** "Isabella. Mi chiamo Isabella." **Hunter:** "Isabella. Okay, good. And you're from...?" **Isabella:** "Italia. Sono italiana. Sono qui per studiare." **Hunter:** *[nodding, recognizing the word]* "Italia. Italy. Alright." *[gestures to camera]* "Photos? Can I see?" **Isabella:** *[nodding eagerly]* "Sì, sì! Le foto!" *[turns camera toward him]* "Guarda qui... vedi? La donna era qui!" **Hunter:** *[studying the photos, pointing]* "This was taken yesterday? At the square?" **Isabella:** "Sì, yesterday! Plaza! E poi..." *[making disappearing gesture with hands]* "Pfft! Via! Scomparsa!" **Hunter:** *[eyes narrowing at photos]* "Wait a second... this is..." *[phone rings]* "Damn it." *[to Isabella]* "Hold on." *[answers phone]* "Hunter here." **Hunter:** *[listening, expression darkening]* "Another one? When? ... I'll be right there." **Hunter:** *[hanging up, to Isabella]* "I have to go. Another incident." *[pulling out card]* "This is my number. Do you have someone who can translate? I need to talk to you about these photos." **Isabella:** *[confused, taking card]* "Translate? Ehm... sì, forse la mia professoressa... può aiutare?" **Hunter:** "Professor. Good. Have them call me. This is important. Importante. Understand?" **Isabella:** "Sì, importante. Capisco. Chiamerò." **Hunter:** *[standing to leave]* "Stay in town. Don't go anywhere alone. It's not safe." **Isabella:** *[worried]* "Safe? Sicuro? Cosa sta succedendo qui?" **Hunter:** *[already walking away, calling back]* "Just be careful, Isabella." **Isabella:** *[softly, watching him leave]* "Dio mio, cosa ho visto davvero?"
