**Scene: A quiet corner café in Alborn, MN** Maria sat at a small wrought-iron table near the window, her half-finished café con leche growing cold beside her. The afternoon light filtered through the glass, casting soft shadows across the tiny screen of her camera as she scrolled through the photos she’d taken that morning—golden apple orchards, frost-laced fences, and one unsettlingly empty dirt road that now made her stomach twist. The bell above the café door jingled. Heavy boots crossed the wooden floor. Hunter stopped beside her table, his worn leather jacket still carrying the sharp scent of the October wind. He gave a short nod, the kind that said *business, not small talk.* **Voice Sheet** Maria: “Ay, Dios mío… no puedo creer lo que vi…” *(voice trembling, eyes still fixed on the camera screen, clearly shaken)* Hunter: “…Ma’am?” Maria: “Esa carretera… estaba vacía, completamente vacía, y entonces… no sé cómo explicarlo. Desaparecieron. Los dos chicos. En un segundo no estaban. Pensé que mi cámara se había roto, pero… los oí gritar. Solo un segundo. Después nada.” Hunter: “I’m sorry, I don’t… I don’t speak Spanish. English? Do you speak English? I’m Detective Hunter. I’m looking into the disappearances that happened near the old mill last week. Did you see something?” Maria: “No entiendo nada de lo que dices… Pero vi algo horrible. Tenían miedo. Mucho miedo. Y después… se los tragó la nada.” *(voice cracking, she finally looks up at him, eyes wide and glossy)* Hunter: *(rubbing the back of his neck, visibly frustrated)* “Look, I can tell you’re upset. Something bad happened. If you saw the missing kids, or anyone acting strange near the orchards, I need to know. Just… point, write it down, anything. I’m not here to hurt you.” Maria: “La cámara… mira. Mira la última foto. Por favor.” *(turns the camera toward him with shaking hands, showing a blurry streak of color where two figures should have been)* Hunter: “Is that…?” *(leans in, studying the image, brow furrowed)* Maria: “Están desapareciendo. Uno por uno. Y nadie hace nada. Nadie escucha.” Hunter: “I wish I knew what you were saying, lady. You look scared half to death. Whatever you saw, it’s got you rattled. If you remember anything useful— anything at all—come by the station. It’s the brick building on Maple. Just ask for Hunter.” *(Maria bites her lip, clearly wanting to explain but unable to find the words. The silence stretches between them, thick and awkward.)* Hunter’s phone suddenly buzzes loudly against his belt. He checks the screen, mouth tightening. Hunter: “Damn it… I have to take this. Stay safe, okay? And if you remember how to say it in English, find me.” *(He gives her one last frustrated but not unkind look, then turns and strides out of the café, phone already to his ear.)* Maria watches him go, camera clutched tightly to her chest, whispering to herself in Spanish as the café door swings shut behind him.
