**ISABELLA & HUNTER – CAFÉ SCENE** *Voice Sheet* --- **[Scene opens with soft café chatter and clinking cups in the background.]** **00:00:00:00** **Isabella** *(soft, in Italian)* Ah... scusate... il sole. **00:00:02:10** **Hunter** *(polite, stepping closer)* Evening. Mind if I join you? *(Isabella looks up, startled, then gestures to the empty chair. Hunter sits slowly, eyeing her camera.)* **00:00:06:05** **Isabella** *(speaking rapidly in Italian, gesturing to the town square)* **00:00:09:15** **Hunter** *(confused, tilting head)* You’re... happy with the view? *(Isabella nods, then points emphatically at her camera.)* **Isabella** *"Fotografia. Italia."* **00:00:12:20** **Hunter** *(perking up slightly)* Italy? I didn’t know we had exchange students. *(Isabella’s smile fades as she speaks urgently in Italian, pointing toward the river beyond town.)* **00:00:16:10** **Hunter** *(frowning)* Woah—slow down. What’s wrong? **Isabella** *(voice trembling, rapid Italian, mimicking holding a camera, then sudden stillness—her face pales.)* *"Ho visto... una ragazza... vicino al fiume... mercoledì... poi è scomparsa!"* **00:00:22:05** **Hunter** *(reacts to tone, squinting toward the river)* A girl... by the river? *(Isabella nods fiercely, pulls out her camera, scrolls through photos, stops—shows Hunter one. A blurred image of a girl in a blue jacket near the riverbank.)* **Isabella** *"Questa è lei! È scomparsa!"* **00:00:27:15** **Hunter** *(taking the camera, voice dropping)* This her? When was this taken? *(Isabella points to the date stamp—Tuesday—and holds up three fingers, then one.)* **Hunter** Last Wednesday... You saw her disappear? *(Isabella mimics dropping the camera into her hands, then gestures a sudden vanish—her expression haunted. Hunter exhales sharply.)* **00:00:33:00** **Hunter** You reported this? *(Isabella shakes her head, whispers in Italian.)* **Isabella** *"Non sapevo... everybody says disappearances are... normal?" **00:00:36:20** **Hunter** *(stark, pulling out his ringing phone)* Damn. No, they’re *not*. *(answers phone; steps away as he speaks.)* **Hunter** Carter. What’ve we got? **Isabella** *(calling after him in Italian, desperate)* *"Aspetta! Aspetta! Per favore!"* *(Hunter waves without turning back, already striding off. Isabella slumps in her chair, gripping her camera until her knuckles whiten.)* **[Scene fades with the distant hum of the café and Isabella’s muffled prayer in Italian.]**
