Here is the dialogue between Marie and Hunter, formatted as a voice sheet: Marie: "Alors, cette disparition… c'est ce qui est arrivé. C’est horrifiant." (Troubled) Hunter: "Excuse me, ma'am? I didn't catch that. Could you... speak slowly?" (Slightly confused, trying to be polite) Marie: "Je dis, c'est… c'est terrible. La femme. Elle a disparu." (Shaken, gesturing vaguely) Hunter: "The… the woman? From the cafe yesterday? Did you… see anything happen? Anything unusual?" (Pressing, getting a bad feeling) Marie: "Non! Non, rien. Je… j'étais là, mais je n'ai rien vu. Seulement… les rumeurs." (Wringing her hands, voice trembling) Hunter: "Rumors? What kind of rumors? Who told you?" (Sterner tone, trying to extract information) Marie: "Les gens. Ils parlent. Il y en a eu d'autres, avant." (Looking around nervously, whispering) Hunter: "Others? Are you saying… there have been more disappearances? Here, in Alborn?" (A sudden intensity in his voice) Marie: "Oui. C'est ce qu'ils disent. C'est pourquoi je… je suis nerveuse." (Drawing her gaze back to her camera, then quickly away from it, wide-eyed) Hunter: "Look, I need to know exactly what you heard. And who you heard it from. This is important." (Leaning forward, his expression unyielding) Marie: "Mais… je ne comprends pas. Je ne peux pas. Je… je ne parle pas anglais." (Frustration mixed with fear, a tremor in her voice) Hunter: "You… you don't speak English? Not at all?" (His brow furrowing in utter bewilderment, a hint of exasperation) Marie: "Non. Seulement français." (Shaking her head, a desperate look in her eyes) Hunter: (Sighs audibly, rubs the back of his neck) "Well, this is just great. Okay, okay, calm down. Take a breath." Marie: (Looks at him, bewildered by his change in demeanor, still visibly distressed) Hunter: "Just… try to point. Or… show me. Anything. Did you see anything or anyone suspicious *before* yesterday's event?" Marie: "Je… je ne sais pas comment vous dire. Je suis ici pour étudier, pour la photographie. Pas pour ça." (Picking up her camera and clutching it, her voice filled with despair) Hunter: (His phone rings, jarringly loud in the cafe) "Hold on. Detective Hunter." (Walks a few steps away, talking in a low, urgent tone into the phone) "What? When? I'm on my way." Hunter: (Turns back to Marie, a grim look on his face) "Look, I'm sorry, I have to go. Something just came up. Don't… don't go anywhere. I'll… I'll try to find someone who can translate. Stay here, okay?" Marie: "Vous… vous partez?" (Her voice small and questioning, a fresh wave of anxiety washing over her) Hunter: (Already half out the door, throwing a quick, concerned glance back) "I'll be back. Stay safe." (He rushes out of the cafe)
