Model response

Selvi: *(muttering to herself in Hindi, looking troubled at her camera)* Yeh kya tha... woh aadmi... maine dekha... Hunter: Excuse me, miss? I couldn't help but notice you seem upset. I'm Detective Hunter with the Alborn PD. Mind if I ask—did you see anything unusual at the apple festival last night? We're looking into a missing person. Selvi: *(shaken, eyes wide, responding urgently in Hindi)* Haan, maine dekha! Ek aadmi... raat ko, festival ke paas jungle mein... woh kisi ko kheench raha tha! Main darr gayi... photographer thi main, camera se click kiya, lekin ab photo gayab hai! Kya karun? Hunter: *(looking confused, furrowing his brow)* Uh... I'm sorry, I don't understand. Do you speak English? Anything about the festival? Missing girl—red dress? Selvi: *(gesturing frantically, still in Hindi, voice trembling)* Nahi, English nahi aati! Aap samjho na... woh ladki thi, laal dress mein! Jungle ki taraf le ja raha tha. Meri photo... oh deva, koi madad karo! Hunter: *(scratching his head, trying to piece it together)* Okay, slow down. Festival? Jungle? Red dress? You took a picture? If you could just... show me? *(pulls out his notebook, mimicking a camera)* Selvi: *(nodding vigorously, in Hindi, handing over her camera with shaky hands)* Haan, yeh dekho! Photo thi yahan, ab nahi. Koi hack kiya shayad. Main India se hun, yahan akeli... dar lag raha hai. Hunter: *(examining the camera, still puzzled)* India? Got it, you're not from around here. This photo—it's gone? Damn. Look, if you saw something in the woods by the festival, that's huge. Can you draw it? Or come down to the station? *(Hunter's phone rings loudly)* Hunter: Hold on—Detective Hunter. Yeah? Another lead? Shit, I'm on my way. *(to Selvi, apologetic)* Sorry, ma'am, duty calls. Stay safe—I'll find a translator and follow up. Don't go anywhere alone. Selvi: *(in Hindi, looking more anxious)* Ja rahe ho? Ruko, aur batao! Main kya karun ab?
