Isabella: "Mi dispiace, sono molto turbata. È successo qualcosa di brutto qui in Alborn e non so se posso parlarne." Hunter: "I don't speak Italian. English?" Isabella: "Non posso parlare in inglese ora; parlerò in italiano." Hunter: "Then tell me in simple terms, in Italian." Isabella: "La persona era alta, vestita di nero, e sembrava correre via." Hunter: "Where did they go? Which direction?" Isabella: "Non ne sono sicura; la vista era confusa e c'era polvere." Hunter: "Was there any sound? Footsteps, shouting?" Isabella: "Ho sentito passi affrettati e una sirena distante." Hunter: "Okay, that helps. I appreciate it." Hunter: "I have to take this call." Hunter: "I need to leave now. We'll continue this later."
