Jack took up a job almost immediately upon arriving since he is easy unskilled labor and he has the right kind of sunny temperament to make the most out of this situation. So he had enough money to stay somewhere, and he hopes that if his family come here, they can share it. A tiny space, yes, but it's better than being alone. He is watching the television himself when the lights go out. Jack isn't afraid of the dark, he isn't afraid of much, but he is confused by it all the same.

He doesn't jump at the sudden bang but decides to get up anyway in case it's someone who needs help. That's what his family would want him to do. Jack doesn't have a weapon so he just walks into the hallway to see what's on the other side. There's nothing. Instead what happens is he opens the door and the person across from him does the same, the two of them looking at each other from their doorways with no one visible there.

"Did you hear the same thing?"
