Fringe has just entered its long winter's hiatus, which will last until the show returns on January 13 with the episode "Back to Where You've Never Been." The episode, which was supposed to serve as the midseason finale until it was pushed back due to the World Series, looks like an action-packed affair. The episode, by the way, will be written by newcomer David Fury, who penned this season's "Alone in the World," but is better known for writing the iconic LOST episode "Walkabout."

"Back to Where You've Never Been" sees Peter Bishop (Joshua Jackson) build a bridge to the alternate universe in order to enlist Walternate's help in returning to his own timeline. The title of the episode refers to the fact that while Peter is familiar with an alternate universe, it certainly isn't this one, which has forgotten that Peter exists just like the other universe. Here's hoping that this brings us a new hue for the Fringe opening credits -- those are always fun.

The promo for the episode, which aired after Friday night's "Wallflower," features some pretty neat things, including a confrontation between the two Lincoln Lees (Seth Gabel and Seth Gabel) and a meeting between September (the Observer) and Olivia, who in this timeline is unaware of who the Observers are. Might September finally spill the beans about what exactly is going on here? We certainly hope so.

But there's something else about this promo that it might take two or three views to catch. Right after Walternate tells Peter that "not everything is as it seems," we get a quick flash to some tanks (cloning? cryogenic? Bacta?) and then a flash of a very familiar face -- one that we haven't seen since the season one finale, when that very face was sliced in half by a closing portal to the other side. That's right -- David Robert Jones (Jared Harris) -- is returning to Fringe in episode 2.08.

We couldn't be more excited. Check out the promo for yourself below. Fringe will air its midseason premiere, "Back to Where You've Never Been" Friday, January 13 at 9/8c on FOX.
