Maria: "Estoy muy inquieta. En Alborn han desaparecido varias personas y no entiendo qué está pasando." Hunter: "I don't speak Spanish. Can you tell me what happened in English?" Maria: "No hablo inglés." Hunter: "Then please tell me what you know, in any way you can." Maria: "Vi sombras cerca del café y oí una conversación en voz baja junto a la plaza. Después, el silencio cayó." Hunter: "Shadows near the cafe? Was anyone harmed? Any names or hints?" Maria: "No oí nombres. Solo gestos y un murmullo. Pero el miedo se siente en el aire." Hunter: "Okay. I might need a translator to understand you fully, but try to tell me anything that could help." Hunter: "I have to take this." Maria: "Por favor, vuelve pronto." Hunter: "I have to go."
