Marie: "Ma'am, Detective Hunter here. There have been disappearances in Alborn. Did you notice anything unusual today?" Marie: "Je suis bouleversée et inquiète." Hunter: "I don't speak French. Please tell me in English what happened." Marie: "C'est compliqué... quelque chose est arrivé et j'ai peur." Hunter: "What exactly did you see? Be specific." Marie: "J'ai vu des ombres près du café, des silhouettes qui se déplaçaient vite." Hunter: "Shadows near the cafe? Were they people or something else?" Marie: "Des silhouettes humaines, mais elles se sont séparées et puis plus personne." Hunter: "Did anyone interact with you or your camera? Any sounds?" Marie: "Oui, j'ai pris une photo, mais elle est floue." Hunter: "Show me the photo on your camera if you can; we can enhance it later." Marie: "Je peux vous la montrer, mais regardez bien: la silhouette au centre est floue et semble bouger sans raison." Hunter: "Okay. We'll go over it later. For now, stay inside and keep your camera ready." Hunter: "I just got a call—I've got to take this."
