**Scene: The Cozy Corner Café, Alborn, MN – Late Afternoon** Maria sat alone at a small wrought-iron table on the café’s sunny patio, her half-empty café con leche growing cold beside her. She slowly scrolled through the photos on her camera, eyebrows furrowed. The last few images from her morning walk near the old orchard showed something that still made her stomach twist. Heavy footsteps approached. Hunter, in his usual dark jacket and jeans, stopped beside her table. He’d noticed the young woman with the camera around town a few times and figured she might have seen something. **Voice Sheet:** Maria: "…No puedo creer lo que vi… Esa sombra entre los árboles… y luego la chica simplemente… desapareció. Tengo miedo. ¿Qué está pasando en este pueblo?" Hunter: "…Ma’am? I’m Detective Hunter. I was hoping to ask you a couple questions about the festival last weekend. You seen anything unusual?" Maria: "…Por favor, no entiendo. Estaba caminando con mi cámara y vi algo horrible. Una persona… se desvaneció. Como si el bosque se la hubiera tragado. Estoy muy asustada." Hunter: "…Right. I don’t speak… whatever that is. Spanish? You speak English at all? English? Anyone?" Maria: "…Solo hablo español. Lo siento. La chica del vestido azul… ya no estaba. Solo quedó su zapato en la hierba. Tengo las fotos, mire…" Hunter: "…Okay, this isn’t working. Look, if you saw something, I really need to—" Maria: "…¿Por qué me mira así? ¿No me cree? Por favor, ayúdeme." Hunter: "…I’m sorry. I have no idea what you’re saying. Maybe I should find someone who—" Maria: "…Tengo miedo de volver sola a mi habitación. Siento que algo me sigue." Hunter’s phone suddenly buzzed loudly in his pocket. He glanced at the screen, his jaw tightening. Hunter: "…Damn it. I’ve gotta take this. We’ll… figure this out later. Stay safe, okay?" He gave her an awkward nod and strode away, already answering the call. Maria watched him leave, hugging her camera to her chest. The unsettled feeling in her stomach only grew stronger.
