When Peter Bishop (Joshua Jackson) stepped into the Doomsday Device and created a Bridge between the two warring universes of "Fringe," it was in the hope that both sides would come together and save both worlds.
And while the two Fringe teams have been cooperating for most of the fourth season, there's one major roadblock to salvation: a mad man named David Robert Jones (Jared Harris), who may have the means to collapse both universes. In the original "Fringe" timeline, Peter killed Jones before he could travel to the alternate world. But in this new timeline, it may already be too late to undo some of the damage caused by Jones.
On this Friday's episode, "Worlds Apart," the two Fringe teams discover Jones' endgame and attempt to prevent a catastrophic event. In this preview video from Fox, "Fringe" cast members Anna Torv,John Noble, Jasika Nicole and Lance Reddick set the stage for the final three episodes of the fourth season and tease a potentially drastic course of action to stop Jones' plans.
