The cast and producers of Fox’s Fringe gathered at the Fairmont Pacific Rim Hotel in Vancouver on Saturday night to celebrate the Warner Bros. TV series’ 100th — and final — episode. And now we have a title for that ultimate hour.

“It is called ‘An Enemy of Fate,'” series boss J.H. Wyman shared with TVLine on the red carpet.

Episode 100 is the second of two hours airing on Friday, Jan. 18.

And while Wyman leading up to and throughout this final season has repeatedly stressed the emotional stakes for Peter, Olivia, Walter et al during these last 13 episodes, make no mistake — this show is going out with a literal bang as well.

“It’s definitely the biggest season finale we’ve ever had,” Wyman promised. “It’s the most expensive…. It’s massive, really big. I wanted to go out like, ‘Wow, how did they do that?'”

“I wanted to make sure I handled [the action element] and the emotions with equal import,” he added.

Fringe resumes its fifth and final run on Friday, Dec. 7 with this season’s eighth episode, “The Human Kind.” What do you think “An Enemy of Fate” means?
