New 'Fringe' Teaser Reveals Footage from Season 4 (VIDEO)

The big question for fans leading up to season four of "Fringe" is how Joshua Jackson, aka Peter Bishop, will play into the season. I won't reveal any spoilers for those who are behind on the series, but due to the parallel nature of the storytelling in "Fringe," things are getting a bit murky around Peter.

Following the very funny promo video with a twist from Comic-Con, the show has been releasing a series of promo teasers titled "Where is Peter Bishop?" to string us fans along. Each teaser so far has featured season three footage with some spooky video and audio effects, and a flash of images at the end that you can only make out if you go frame-by-frame. Pretty cool.

But the most recent teaser ties them all together and includes the first footage from the new season. Each scene features the same effects, until we get to the last one with the new footage...it's almost as if we're looking in from another universe. Are we seeing things from Peter's point of view, perhaps?

Check out the video below, and let us know if you think you know what these mean...can you see the flashes at the end? What's the secret? Where is Peter Bishop?
