**Scene** In the warm, softly lit Apple Blossom Cafe in Alborn, MN, Selvi sat alone at a corner table near the window. Golden autumn light spilled across her as she scrolled through the photos on her camera, her usual calm expression replaced by visible distress. The images from the recent apple festival had taken on a darker meaning. Heavy footsteps approached. Detective Hunter, broad-shouldered and serious, stopped at her table. **Voice Sheet** Hunter: "Pardon me, miss. I'm Detective Hunter. I understand you were taking landscape photographs at the apple festival last weekend. We've had some mysterious disappearances. Did you see anything unusual that day?" Selvi: "Haan, main wahan thi. Bahut darr lag raha hai. Ek aadmi mere saamne se gayab ho gaya. Meri camera mein kuch ajeeb saya capture hua hai, samajh nahi aa raha kya tha. Main pareshan hoon!" Hunter: "I'm sorry, I don't understand Hindi. Do you speak any English at all? English? If you saw something connected to the missing people, it could be very important." Selvi: "Mujhe English bilkul nahi aati. Sirf Hindi. Yeh dekho photo, ismein woh daravna kuch hai. Log kyun gayab ho rahe hain? Main study abroad ke liye aayi thi, itna sab nahi socha tha." Hunter: "I can see you're shaken, but I have no idea what you're saying. The camera... maybe the pictures will help. Can I look? We need to find a way to communicate here." Selvi: "Camera? Theek hai, lekin please dhyan se. Yeh photo dekho, yeh normal nahi hai. Main bahut ghabraayi hui hoon, kuch toh galat ho raha hai is sheher mein." Hunter: "You're clearly trying to tell me something critical. I wish I spoke Hindi. Just slow down and maybe point. This investigation is going nowhere until we can understand each other." Selvi: "Main kya karun? Aap samajh nahi rahe. Main sirf itna keh rahi hoon ki maine kuch bhayanak dekha aur meri camera ne usse record kar liya. Madad chahiye." Hunter: "This call is from the station. I have to go right now. I'll come back with someone who speaks Hindi. Stay safe until then." Hunter nodded once in awkward farewell and strode out of the cafe, leaving Selvi still clutching her camera, the weight of unspoken words hanging between them.
