With the Fringe season 4 finale behind us, there are still a lot of unanswered questions about the Fox series! TVGuide sat down with executive producers J.H. Wyman and Jeff Pinker to discuss what’s coming up in the series’ fifth and final season. Lots of spoilers ahead!

From the interview:

Are you going to stay in the current timeline, or will we see some flashing forward and backward next season?
Wyman: Well, let’s say that basically 2036 is extremely important to Season 5. It’s crucial, but having said that, everything that you have seen in Fringe from Season 1 all the way to 4 is really, really, really, really important to what’s going on in Season 5, and 2036 is part of that. It’s a 13-episode sprint; there’s no filler episodes. It answers some very bold questions. It culminates with a very satisfying type of crescendo that really is so important for the fans, that’s the biggest thing. That’s the only thing that’s really important is to make sure that they feel absolutely satiated.

Because Olivia did technically die in the finale, does this mean that was the moment September had envisioned? And, will she always heal rapidly and now never die?
Wyman: At the end of every season, we close a chapter, and you’ve heard us say that before, but this chapter being closed is a gentle closing for a reason. We wanted to allow the characters to be in the emotions that they fought for and deserved and allow them to experience a little bit of peace and understand where they are.
Jeff Pinkner: Part of the answer to your question is yes, Olivia healed because of all the cortexiphan. At the end of Season 4, as Walter said on the screen, because of the wildly activated cortexiphan in her body, this experiment to heal her brain tissue would work. Because that’s not constantly the case, because that’s just a fleeting condition, absolutely, she could be killed.
Wyman: They don’t know if anything is over. So they’ve been given that warning. I think that it’s best to have the audience not know either and be with them in that trepidation of going forward, going, “Well, maybe.” That’s more like real life, isn’t it?

The interview has a TON of additional info, about the “X Man,” Olivia’s pregnancy, the Fringe division and more! Check it all out here.
