Model response

AI
Here is the dialogue between Maria and Hunter, formatted as a voice sheet: **Maria:** (Looking up, startled) "Lo siento, ¿qué?" **Hunter:** "I'm Detective Hunter. Are you Maria? I'm investigating the recent disappearances in Alborn. Were you by the old mill pond yesterday evening?" **Maria:** (Eyes wide, speaking quickly, a tremor in her voice) "¡Ay, Dios mío! Desapariciones... Sí, lo sé. Anoche... vi algo cerca del bosque. Una luz extraña, muy lejos, y luego... silencio. Estoy... estoy tan asustada." **Hunter:** "Whoa, whoa. Slow down. I... I don't understand. Do you speak any English?" **Maria:** (Shakes her head vigorously, fear and frustration in her eyes) "No, no inglés. Solo español. Le digo que tengo miedo. Vi... pude sentirlo. El miedo. ¿Él es... él se ha ido?" **Hunter:** (Rubs the back of his neck, gestures towards her camera) "Okay, 'no English.' Got it. Look, can you... can you try to show me what you saw? Maybe on your camera?" **Maria:** (Hesitantly brings up a blurry photo on her camera) "Aquí, Detective. Estaba oscuro, ¿entiende? Yo hacía fotos del atardecer y... y noté algo. No sé qué. Solo... una sensación muy fría. Me hizo temblar." **Hunter:** (Squints at the camera screen, gestures vaguely at the forest in the photo) "So, you saw something *there*? Something related to the missing people?" **Maria:** (Nods, her lips pressed into a thin line) "Sí. No a las personas directamente, pero... la razón. El mal. Lo vi." **Hunter:** (Looks around, exasperated, then pulls out his ringing phone) "Hold on a sec." **Hunter:** (Into phone, urgently) "Yeah, Hunter. What? No, no way. I'm on my way. Be there in five." **Hunter:** (To Maria, now urgent) "Look, I gotta go. Emergency. This is important, Maria. I'll... I'll find someone who can translate. Don't go anywhere, okay? Or at least, come back here." **Maria:** (Looks troubled, a flicker of panic in her eyes, nods slowly) "Sí... entiendo. Iré aquí. Tenga cuidado, Detective." **Hunter:** "Right. Be careful, you too."
