Ever since the end of Fringe season three, we've been wondering what's up with Peter Bishop. Does this video which played at the show's Comic-Con panel give a hint?

Spoilers ahead...

And at the Fringe pressrooms last weekend, the producers started to say we should be wondering what character Joshua Jackson is playing this fall — and then they caught themselves before they even finished their sentence.

Now it seems like a major clue about the direction of Fringe's next season has been released. Check out the above Comic-Con video, in which various famous actors audition for the role of Peter Bishop. Make sure to watch until the very end, at which point a surprise is revealed... Or is it? After this video was shown, Peter came out on stage at Comic-Con in his Observer outfit, and the producers acted as though it was just a joke. [Thanks to Lucien!]
