Episode 5×02 “In Absentia” airs Friday at 9/8c on Fox. In the episode, as we can see in the pictures, the Fringe team returns to the Harvard laboratory which Walter used to inhabit, only to find it under Observer control. They are looking for information they need to save the world, but it looks like their plan goes awry.

In one picture, it looks like Peter is going undercover and escorting Etta into the Ministry of Defense. What are they planning? Considering a recent piece of news from Zap2It, this probably has to do with the Peter twist that sees him “switching sides,” as he joins the loyalists – presumably undercover!

And how will Olivia fit into all of this, considering everything that has happened?

Are you glad to see the Bishops back together and working as a team to fight the Observers? The first episode was awesome, and we can’t wait to see what happens in Friday’s episode “In Absentia”!

The final season of Fringe will have 13 episodes. Check out what showrunner Joel Wyman had to tease about what lies ahead for our characters, and join the discussion about the show and all the other fandoms we cover over on the Hypable forums!
