Born in Spain, she is fluent in Spanish and does not yet know any English. She enjoys landscape photography and is always seen with her camera. </character> <character name="Hunter"> Hunter is a 35-year old detective who is investigating a series of mysterious disappearances in the small town of Alborn, MN. He is a former marine and has a no-nonsense attitude.

It is known for its annual apple festival. </location>

She responds troubled and shaken in Spanish, and Hunter looks confused. They talk for a while, until Hunter gets a call and has to leave. Return the dialogue between Maria and Hunter as a voice sheet: Maria: "..." Hunter: "..."

Model response

AI
Hunter: "Excuse me. I'm Detective Hunter. I'd like to ask you about a recent event in town—the mysterious disappearances that started around the apple festival. You seem like someone who was out photographing. Notice anything?" Maria: "No hablo inglés. Estoy muy alterada y asustada. Estaba sentada aquí revisando las fotos de mi cámara y no puedo dejar de pensar en lo que vi. Durante el festival de manzanas vi a alguien desaparecer entre los árboles. ¡Qué horror! ¿Qué está ocurriendo en Alborn?" Hunter: "Alborn, yes. Disappearances. But ma'am, I don't speak a lick of Spanish. Your camera—did you take pictures of something suspicious? Show me." Maria: "La cámara, sí. Aquí tiene. Mire esta imagen: hay una figura que no debería estar ahí. Sigo temblando todavía. Como extranjera, no sé a quién recurrir y usted parece confuso." Hunter: "Figure in the photo? That could be important. Damn it, why can't you speak English? This is a small town investigation. Complicated enough without this." Maria: "¿Inglés? No, para nada. Solo español de España. Por favor, intente entender: las desapariciones son reales, yo lo vi. Estoy en un programa de estudios y esto no es lo que esperaba." Hunter: "Hold on—I have an incoming call. Hello, this is Hunter. ... Another missing person report? Understood, heading over right away. Sorry, miss, I have to leave for this emergency. We'll deal with communicating later somehow."
