It is known for its annual apple festival. </location>
User/Human

Model response

AI
Isabella: *(scrolling through her camera, murmuring to herself)* "Non riesco a crederci... era proprio qui. L'ho fotografato senza nemmeno accorgermene." Hunter: *(approaching, pulling out a small notepad)* "Excuse me, miss. Detective Hunter, Alborn PD. Mind if I ask you a few questions about what happened down by the orchard last night?" Isabella: *(looking up, startled, eyes wide)* "Oh—Dio mio. Sì, sì, ero lì! Ho visto qualcosa, ma... ma non so come spiegarlo. C'era un uomo, e poi—" Hunter: *(brow furrowing)* "I'm sorry—I didn't catch any of that. You were there? Last night?" Isabella: *(speaking faster, hands trembling)* "Le mie foto! Guardi, guardi qui—" *(turning the camera toward him)* "—c'è una figura, vede? Vicino agli alberi. Avevo tanta paura. Ho sentito un urlo e sono scappata." Hunter: *(leaning in, squinting at the screen, then back at her face)* "Okay—slow down. I don't... I don't speak Italian. You took a picture? Is that what you're showing me?" Isabella: *(frustrated, pressing a hand to her chest)* "Non capisce niente di quello che dico, vero? Per favore—è importante! Qualcuno è sparito, lo so. L'ho visto con i miei occhi." Hunter: *(rubbing the back of his neck)* "Alright, alright. Let's just—the photo. Can I see the photo? Photo." *(miming holding a camera)* "That. Yes?" Isabella: *(nodding rapidly, relieved)* "Sì! Sì, la foto. Ecco." *(handing it over carefully)* "Stia attento, per favore. È tutto quello che ho." Hunter: *(taking the camera, studying it intently, voice low)* "...Well, I'll be damned. There's somebody in the treeline. This could be exactly what we've been—" *(His phone buzzes loudly. He glances at it, expression hardening.)* Hunter: "Hunter. ...Where? ...No, don't touch anything, I'm on my way." *(pocketing the phone, handing the camera back)* "Listen—I have to go. But this? This is important. Stay here. Stay—" *(pointing firmly at the table)* "—here. I'll bring someone who can actually understand you. Okay?" Isabella: *(clutching the camera to her chest, confused but earnest)* "Aspetti—dove va? Cos'è successo? Mi dica qualcosa!" Hunter: *(already backing away)* "I'll be back. Don't go anywhere." *(over his shoulder, quietly)* "God, I hope she stays put." Isabella: *(watching him rush off, sinking back into her chair)* "...Tornerà. Spero che torni. Perché qualcosa, in questo posto, non va per niente bene."
