Selvi: "Main... maine kal shaam festival mein ek aadmi ko dekha tha, wo kisi ko kheench raha tha taraf... bahut darr lag raha hai mujhe." Hunter: "Excuse me, miss. I couldn't help but notice you were at the apple festival last night. I'm Detective Hunter with the Alborn PD. Did you see anything unusual? Any of the missing persons?" Selvi: "Kya? English nahi aati mujhe... woh... woh andhera tha, aur awaaz aayi thi... please, madad karo!" Hunter: "Uh, okay... do you speak any English at all? This is important—there've been disappearances. Point? Gesture? Anything?" Selvi: "Nahi, nahi samajh rahi... camera mein photos hain, dekho? Ek ladki gayab ho gayi, maine usko dekha tha akele!" Hunter: "Photos? Your camera? Can I—wait, slow down. You're shaken up. Here, let me try to get a translator on the phone. Just nod if you saw something suspicious." Selvi: "Haan, suspicious... bohot darawna tha. Koi madad nahi mili usko. Police kya kar rahi hai?" Hunter: "Alright, nod if yes—did you witness an abduction? *Phone rings* Damn, hold on. Detective Hunter—yeah, I'm in the middle of an interview... Got it, be right there. Sorry, miss, duty calls. We'll follow up—stay safe, okay?" Selvi: "Jao? Par... suno na!"
