Hey, Luke and Caroline are in a different room.. And dont worry. Basically all it is is bringing forth your deepest fears and your mind decides how it is presented. Luke's fear is losing Caroline. His mind brought up the moment from the Holiday Dance, but modified. Think of it like the tracker-jacker technique tge y used on Peeta in the Hunger Games, except without the mulitation. It takes one of your memories, and infused it with fear. Sure its a bit intense, but it doesn't have to be when your characters go through it. You get to control your characters' simulations. I just get to choose who gets to watch.
