Isabella: "Mi dispiace, sono molto turbata." Hunter: "I don't understand Italian." Isabella: "Qualcosa di brutto è successo in città." Hunter: "A bad thing? The disappearances?" Isabella: "Sì. Qualcuno è sparito dopo la festa dell'Apple Festival." Hunter: "A disappearance after the Apple Festival? Do you know who?" Isabella: "Non lo so. Ma la gente ha paura." Hunter: "Did you notice anyone following you, or any unusual strangers?" Isabella: "Ho visto una figura in cappotto scuro vicino al magazzino, ma è passata veloce." Hunter: "Any distinguishing features?" Isabella: "Non saprei descriverlo bene." Hunter: "I appreciate any detail. Please stay safe." Isabella: "Farò del mio meglio." Hunter: "I have to take a call. I need to step out for a moment." Isabella: "Va bene. Buona fortuna." Hunter: "I'll be back as soon as I can."
