There is a lot of talk about a war that is due, the shape changing FBI agents and those kinds of things but one asked why again now. Probably it is because Olivia knows something about something that she should not but the problem being that he is stuck in some other reality she has no idea of what really happened and what is happening again and hopefully all these questions will be answered in this episode or if not all than some would be. The Fringe team starts digging through the scenario of what Livy did before the accident happened. You might have heard it before but what if Walter make a fringe-y cocktail in order to make her remember which would also mean we all get to see William Bell once again with Leonard Nimoy as the guest star and we also see a bit of Messrs. Leaving Bisop’s and Bell’s experiments behind, the girl with the wires in her head also comes back.

The team will investigate many robberies which they think are linked to the shape shifting and for started its very hard to track someone in this situation and I think it will not be Charlie.
