Take the following details about characters/locations/... into account: <character name="Marie"> Marie is a 30-year old college student on a study abroad program. Born in France, she is fluent in French and does not yet know any English. She enjoys landscape photography and is always seen with her camera. </character> <character name="Hunter"> Hunter is a 35-year old detective who is investigating a series of mysterious disappearances in the small town of Alborn, MN. He is a former marine and has a no-nonsense attitude. Hunter has no knowledge of French, not even basic phrases. </character> <location name="Alborn, MN"> Alborne is a small town in the Midwest with a population of 3,000. It is known for its annual apple festival. </location>
User/Human
Write the following scene: Marie is sitting at a cafe, looking at her camera. Hunter approaches her and asks her about a recent event in the town. She responds troubled and shaken in French, and Hunter looks confused. They talk for a while, until Hunter gets a call and has to leave. Return the dialogue between Marie and Hunter as a voice sheet: Marie: "..." Hunter: "..."

Marie: *looking troubled, fiddling with her camera, muttering to herself* Mon Dieu, ces photos... c'est impossible... Hunter: Excuse me, miss. I'm Detective Hunter. Saw you here with that camera—mind if I ask about the apple festival last night? There was a disappearance near the cider tent. You notice anything unusual? Marie: *shaken, eyes wide, speaking rapidly in French* Non, non! J'ai tout vu! L'homme... il était là, et puis une ombre l'a emporté! J'ai pris une photo, regardez! C'était horrible! Hunter: Uh... sorry? English? Did you see something? Festival? Disappearance? Marie: *gesturing frantically at her camera, voice trembling* La photo! Regardez la photo! Il y avait quelqu'un de suspect, avec un chapeau... il a suivi l'homme vers les arbres! Hunter: Photo? You took a picture? *leaning in, confused* Can you show me? Show? *mimes camera* Marie: *flipping through photos shakily, pointing* Ici! Voyez? L'ombre... elle bouge! Je suis terrifiée, monsieur! Appelez la police! Hunter: Whoa, okay, that's... blurry. Shadow? Suspect? *scratching head* Ma'am, I don't understand. You need to— *Hunter's phone rings loudly* Hunter: Hold that thought—one sec. *answers* Hunter here. Yeah? Now? Shit, on my way. *to Marie* Sorry, gotta run—urgent. Stay here, okay? We'll figure this out! *rushes off*
