**Voice Sheet — Café Scene, Alborn, MN** *(Selvi sits at a small corner table, scrolling through photos on her camera. Her hands tremble slightly. Hunter enters, spots her, and approaches with his usual brisk stride.)* Hunter: "Excuse me — you're the exchange student staying near the Millers' place, right? Selvi?" *(Selvi looks up, startled. She nods but says nothing at first, her eyes darting back to the camera screen.)* Hunter: "I heard you were out near the old mill trail yesterday evening. Around the time Mrs. Petrov went missing. Did you see anything unusual?" Selvi: *(voice shaking)* "मुझे... मुझे कुछ अजीब दिखा था। एक साया, पेड़ों के बीच। मैं डर गयी थी।" *("I... I saw something strange. A shadow, between the trees. I got scared.")* Hunter: *(blinking, confused)* "Whoa — slow down. I don't— I don't understand a word of that. English? Do you speak any English?" Selvi: *(shaking her head, frustrated with herself)* "नहीं... नहीं समझ रही मैं। सॉरी।" *("No... I don't understand. Sorry.")* *(She holds up the camera toward him, flipping through images with unsteady fingers. One photo shows a blurred figure at the edge of the woods.)* Hunter: "Okay — okay, hold on. You took pictures? Can I see?" *(He leans in, studying the screen. Selvi points at the blurry shape, tapping the screen twice, her breath quickening.)* Selvi: "यह... यह वही साया है। मुझे बहुत डर लगा था वहां।" *("This... this is the same shadow. I was very scared there.")* Hunter: "I wish I knew what you were saying. That shape — can you zoom in? Enhance it somehow?" *(Selvi, sensing his intent despite the language gap, fumbles with the camera buttons, enlarging the image. Hunter's eyes narrow at the screen.)* Hunter: "That's... near the ravine. That's not far from where the Hendersons' barn burned down last spring." Selvi: *(quietly, mostly to herself)* "मुझे नहीं पता यह क्या था। पर वो बहुत डरावना था।" *("I don't know what that was. But it was very frightening.")* *(Hunter's phone buzzes. He pulls it out, glancing at the screen, his jaw tightening.)* Hunter: "Dispatch. I have to take this." *(into phone)* "Hunter here. What've you got?" *(He listens for a moment, expression darkening.)* Hunter: "Copy that. I'm on my way." *(to Selvi, gesturing at the camera)* "Don't delete that photo. I'll get someone who speaks Hindi to come talk to you properly. Stay put, alright?" Selvi: *(nodding, though clearly not understanding every word, sensing the urgency)* "ठीक है... ठीक है।" *("Okay... okay.")* *(Hunter hurries out of the café, leaving Selvi alone with her camera, staring at the blurred shadow on the screen, her hands still trembling.)*
