After four episodes of ghostly visitations, disembodied voices and brief cameos in reflective surfaces, Peter Bishop (Joshua Jackson) is back from non-existence, which, ordinarily, would be cause for celebration.

Unfortunately for 'Fringe' fans, there's still the small issue of no one remembering who Peter is, which means that the tearful reunions might be a long time coming -- especially since there's no new episode this week.


Last month, AOL TV traveled to Vancouver to catch up with the cast of the Fox drama (Fridays at 9PM ET) and find out what's coming up for our intrepid Fringe divisions -- on this side and the other.

After the jump, Anna Torv, John Noble, Jasika Nicole, Seth Gabel and Lance Reddick weigh in on what Peter's return will mean for the team, how the addition of Lincoln will change the character dynamics and how the working relationship between the two universes will evolve. Warning: Spoilers ahead.

Where's Peter Bishop? It's the question that has plagued the 'Fringe' (Fri., 9PM ET on FOX) marketing team all summer. In the Season 3 finale, he sacrificed his very existence in an attempt to save two worlds. Now there's a meeting place where the two realities co-exist, but Peter never was.

His absence rewrote bits of the timeline, like Olivia and the team having not yet met Lincoln Lee. More specifically, though, it's left Walter even more agitated and untethered, while Astrid seems a little harsher toward him than we remember. But where's Peter?

The Observer -- the one we've been seeing since the beginning -- noted that he's not as fully erased as he should have been, but as some part of him caused him to interfere in the natural order of things once before, he again could not complete the task of finally erasing Peter from existence.

So you've heard the buzz, your interest is tickled and you're ready to take the plunge into a new show. But, you don't have time to catch up on multiple seasons?

Have no fear, AOL TV is here. We'll be spotlighting five episodes from some of the best scripted comedies and dramas on TV that you need to see before jumping into the new season this fall.

Up now? 'Fringe.'

Starring Anna Torv as FBI Agent Olivia Dunham, 'Fringe' is a sci-fi FBI drama set in the world of fringe science. But before you run screaming from the room, just know that it's much more than an 'X Files' rip-off.

Created by J.J. Abrams, Alex Kurtzman and Roberto Orci, 'Fringe' is about love, loss and redemption. It's smart, funny, challenging and moving.

So what did the stars and producers of 'Fringe' reveal about the show's fourth season at the show's Comic-Con panel on Saturday? Absolutely nothing. Yet the panel was still enjoyable, even if I have no idea how Peter Bishop will be re-integrated into the world of 'Fringe' when the show returns.

The stars were, of course, willing to talk about 'Fringe''s excellent third season (check out the video interviews below for more on that), and the panel began with a funny video clip -- "auditions" for the role of Peter who, of course, is played by Joshua Jackson.

The actor wasn't scheduled to be part of the panel, but he turned up in an Observer suit and hat as the session was getting underway. So how will his character return when Season 4 begins? "All will be answered, we promise," executive producer J.H. Wyman said.

Just not right now.
