Olivia returns from the alternate reality and Peter tries to get information about her visit. Walter makes some custard for his son's birthday, while Broyles deals with the threat of a government shutdown of the Fringe Division.
What a episode, this had everything I wanted, the twist was kind of predictable but the idea of it is fantastic, the episode was fast paced, well acted and just what you would come to expect from this show, it just gets better and better. Walter is as funny as ever. I like the new character Amy and it was good to see Peter get loads of screentime. Awesome episode
