Hunter: Miss, I'm with the Alborn Police. Can you tell me what you saw about the recent disappearances in town? Isabella: Mi dispiace, non parlo l'inglese; sono molto spaventata. Hunter: I can't understand you. Is there anyone who can translate for you? Isabella: Qualcosa di brutto è successo qui in città la notte scorsa. Le strade sono vuote e ho visto ombre. Hunter: I still can't understand you. Please, tell me in simple terms what you saw—if you can. Isabella: Ho appena scattato una foto. Hunter: A photo might help. Let me see. Isabella: La foto è sul mio telefono. Hunter: I have to take this—it's urgent.
