Only one world will survive in the Fringe season finale.
In the two-hour episode, airing on May 11, David Robert Jones (Jared Harris) will try to destroy the two universes to create a new one that he'll control. And from the looks of it in the trailer below, William Bell (Leonard Nimoy) is alive and helping him.
"The man I knew wouldn't try to destroy a universe," Nina shouts before the trailer is cut off. Guess we'll have to wait until next week to learn more.
Fringe airs Fridays at 9/8c on Fox.
