Marie: "Je suis troublée et ébranlée. Je regardais mes photos sur mon appareil quand vous vous êtes approché." Hunter: "I don't speak French. Have you heard anything about the recent disappearances in Alborn?" Marie: "Je ne parle pas anglais." Hunter: "Then tell me in any way what you saw." Marie: "J'étais assise ici, à prendre des photos près de la place, quand des silhouettes et une voiture noire ont été vues. Puis tout s'est accéléré et la rue est devenue silencieuse." Hunter: "A car, silhouettes... anything more specific? Time? Location?" Marie: "La lumière autour de la fontaine s'est éteinte juste avant le départ de la voiture." Hunter: "Okay. I think I have something to go on." Hunter: "I have to take this call. I'll come back as soon as I can."
