Take the following details about characters/locations/... into account: <character name="Selvi"> Selvi is a 30-year old college student on a study abroad program. Born in India, she is fluent in Hindi 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. Hunter has no knowledge of Hindi, not even basic phrases. </character> <location name="Alborn, MN"> Alborne is a small town in the Midwest with a population of 3,000. It is known for its annual apple festival. </location>
User/Human
Write the following scene: Selvi is sitting at a cafe, looking at her camera. Hunter approaches her and asks her about a recent event in the town. She responds troubled and shaken in Hindi, and Hunter looks confused. They talk for a while, until Hunter gets a call and has to leave. Return the dialogue between Selvi and Hunter as a voice sheet: Selvi: "..." Hunter: "..."

Model response

AI
Selvi: (muttering to herself softly, looking troubled at her camera screen, in Hindi) Yeh kya tha... maine sahi dekha na? Ek aadmi... kisi ko kheench raha tha... Hunter: Excuse me, miss. I'm Detective Hunter. Saw you with that camera—mind if I take a look? We're asking folks about anything unusual at the apple orchard last night during festival setup. Did you see something? Selvi: (shaken, eyes wide, voice trembling, in Hindi) Nahi, nahi! Maine dekha... raat ko orchard mein... ek aadmi tha, kaala coat, kisi ladki ko zabardasti jungle ki taraf le ja raha tha! Bhoot jaise! Main darr gayi... camera click ho gaya! Hunter: (confused frown, leaning in) Uh... ma'am? English? Do you speak any English? Orchard? Last night? Selvi: (frantic, shaking head, pointing urgently at her camera screen, showing a blurry night photo of shadowy figures, in Hindi) Dekho! Yeh photo! Proof hai! Police aao, please! Main India se hoon, yahaan akeli... dar lagta hai! Hunter: (squinting at the photo, nodding slowly, trying gestures—points at photo, then mimes dragging motion) This? You saw this? A man... dragging? (pulls out notebook, mimes writing) Name? Your name? Selvi: (nods vigorously, still shaken, tapping her chest, in Hindi) Selvi! Selvi hoon main. College student. Yeh Alborn mein pehli baar... par yeh ghalat hai! Aur log gayab ho rahe hain, newspaper mein padha! Hunter: Selvi, got it. (smiles reassuringly, no-nonsense tone) Okay, Selvi. Stay here—I'll get interpreter. This photo... important. You help big case. Disappearances. Wait? Selvi: (nervously glancing around cafe, clutching camera, in Hindi) Haan, thik hai... par jaldi aao. Mujhe lagta hai woh aadmi mujhe dekh raha tha... Hunter: (phone buzzes loudly; he checks it, face hardening) One sec— (answers) Hunter. Yeah? Another van by the lake? Missing person? On my way—tell 'em to hold the scene. (to Selvi, apologetic) Selvi, gotta go. Stay put, okay? Patrol car's coming. Show 'em this. (points at camera, hurries off)
