Maria: "Hey there. I'm Detective Hunter. I'm investigating the disappearances in Alborn. Did you see anything unusual around town today?" Hunter: "I'm actually Detective Hunter. I'm investigating the disappearances in Alborn. Did you see anything unusual around town today?" Maria: "Estoy muy preocupada y asustada. Anoche, alguien desapareció cerca de la plaza. La ciudad está en silencio y la gente evita mirarse. No hablo inglés." Hunter: "I don't speak Spanish." Maria: "No hablo inglés." Hunter: "Then tell me what you saw as best you can, and I'll get someone to translate." Maria: "Podemos intentar ayudar, pero no aquí." Hunter: "If you saw anything—any detail at all—describe it." Maria: "Vi a un hombre con una chaqueta verde cerca de la estación la noche de la desaparición." Hunter: "That could help." Hunter: "I have to take this call from the precinct."
