Comic-Con 2011: 'Fringe's' Joshua Jackson Reveals Peter's Whereabouts and His Ideal Return (Video)

The actor shared his thoughts with THR on whether the world is a better place with or without Peter.

Joshua Jackson made a splash at Comic-Con on Saturday when he crashed the Fringe panel in Ballroom 20, but did his surprise appearance mean Peter actually does exist?

The Dawson's Creek vet spoke to The Hollywood Reporter about just that, but not surprisingly, gave away very little. Even the recently-released Season 4 teaser, continued with the main question at hand: Where is Peter Bishop?

"He's at Comic-Con," Jackson joked.

"It’s going to involve a couple of newer themes. We’re just taking you down the road a little further on the journey," executive producer J.H. Wyman said in a recent interview with THR.

If and when Peter returns to Fringe, Jackson addressed whether the world was better off without his alter ego -- and revealed how Peter should return to existence.

Fringe returns Friday, Sept. 23 at 9 p.m. on Fox.
