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>
User/Human

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, miss. Detective Hunter, Alborn PD. I'm looking into the recent mysterious disappearances around town. Have you noticed anything unusual, maybe while you were out with that camera?" Maria: "¡Ay, Dios mío! Estoy muy alterada y aún tiemblan. Ayer fotografiaba el paisaje cerca del bosque y vi a una mujer... simplemente se esfumó ante mis ojos. Como si el aire la hubiera tragado. No puedo dejar de mirar las fotos." Hunter: "Whoa—sorry, I don't understand a word of that. Zero Spanish. Do you speak any English at all? Anything about the disappearances?" Maria: "No sé nada de inglés, lo siento. Solo español. Pero es urgente. Mi cámara capturó todo. Mire la pantalla, por favor. La secuencia es espeluznante y nadie me cree." Hunter: "Your camera... right, you're pointing at it. Looks like landscape shots of the woods outside town. Something off in the sequence you think? Hard to tell without understanding you. You a student passing through for the apple festival?" Maria: "Sí, soy estudiante de intercambio de España. Vine por el programa y el festival de manzanas, pero ahora solo quiero ayuda. Estaba sola, el aire se enfrió de golpe y... ella ya no estaba. Me siento terriblemente sola y asustada." Hunter: "Festival, got it—the whole town turns out for it. This language barrier is killing me. Maybe we grab a translator and—" Hunter: "Hold on, I've got a call. Detective Hunter. ... Another one? Near the orchard road? ... Understood, heading there now. (to Maria) I'm sorry, miss. Emergency with the case—I have to leave right away. Stay put if you can; I'll find someone who speaks Spanish and circle back." Maria: "¡No se vaya aún! Hay más detalles en las fotos... un hombre extraño de abrigo oscuro justo antes. ¡Por favor, necesito que alguien me escuche!"
