Another week and more mysteries remained to be uncovered. This episode does reveal a lot compared to all the other episodes thus far. We find out who is responsible for the black out, but we're not told if they have tried their experiment before. If you want to watch the show, then I would recommend you watch the episode first and then read this review. I do have some spoilers moments in this review.

Simon:

This episode we get a chance to meet Simon. His dealings with the woman on the train suggest that he is a sleazy dirt bag. He claims to be a quantum physicist and uses his charm to seduce the woman. He even goes as far as sharing his flash forward with her, in which it is revealed that he is killing a man by strangling him. He even admits that he seemed to have enjoyed killing this man according to this flash forward. Questions even Simon does not know are, who is this man he just murdered? why did he murder him? More on Simon a little later.
