Selvi: (looking troubled, speaking in Hindi, voice shaky) Yeh ghatna... bahut darawni thi. Main festival mein thi, lekin woh aadmi... woh gayab ho gaya. Kya karun? Mujhe lagta hai koi dekh raha hai mujhe. Hunter: Excuse me, miss. I'm Detective Hunter with the Alborn PD. Were you at the apple festival last night? Did you see anything unusual around the time of the disappearance? Selvi: (shaking her head, more agitated, in Hindi) Nahi, nahi samajh rahi main! Police? Festival mein ek ladki ne mujhe bataya... woh bhagoda... par main dar gayi. Camera mein kuch shayad... (fumbles with her camera, showing blurry photos) Hunter: Uh, ma'am? English? I'm sorry, I don't follow. You were there? Anything about a runaway or... (pauses, confused, trying to interpret her gestures) A girl? Did someone chase you? Selvi: (voice rising in distress, in Hindi) Haan, woh ladki! Woh chillayi, phir gayab. Main photo li, dekhiye! Koi madad kijiye, please! Hunter: Okay, slow down. Photos? Let me see... (leans in, puzzled) This looks like the festival grounds, but it's blurry. Was there a scream? A chase? I really need you to try English if you can, or maybe I can call an interpreter— Selvi: (on the verge of tears, in Hindi) Interpreter? Hindi bolti hoon sirf. Yeh sheher... yahan sab chhupa rahe hain. Mujhe wapas jaana hai India. Hunter: Hindi? Damn, alright. Hang on, I might know someone at the college who can translate. Just stay calm, you're safe here in Alborn. Tell me more about this girl— (Phone rings) Hunter: Hold that thought. (answers) Hunter here. Yeah? Now? Shit, alright, on my way. (to Selvi) Sorry, ma'am, duty calls. I'll be back with help—don't go anywhere, okay?
