I don't understand.)* Hunter: "The disappearances. People missing. You see anything suspicious?" Maria: "¿Desapariciones? Oh, sí, sí... es muy malo. Muy malo." *(Disappearances?

Spanish.)* Hunter: "Great. Just great." *(pulls out phone, starts scrolling for a translation app)* "Okay, give me a second here..." Maria: "¿Tu... investigas los desaparecidos?" *(You... investigate the disappeared ones?)* Hunter: *(looking up from phone)* "Yeah. You're getting that part, huh?" *(gestures to his badge)* "Detective." Maria: "¡Ay, Dios mío! Vi algo... hace dos noches, cerca del bosque. Una luz extraña y luego... nada.
