Mysterious title of Fringe's series finale revealed

Episode titles in Fox's Fringe are rarely built around a whim. More often than not, they're based on a critical point and tease what the episode is about. Hmm, want to know the mysterious title of the series finale?

Here it is: "An Enemy of Fate."

Showrunner J.H. Wyman spilled the beans to TV Line, and it'll be interesting to see how the future-set season, which finds the team facing off against an enemy that can see the future, wraps things up with an episode about "fate."

What do you think it's referring to? Olivia and the gang, fighting against the inevitable victory of the Observers? Or maybe Peter himself, using his newfound bald skills to take on the Observers and "fate" itself?

For what's it's worth, here's how Wyman described the episode:

"It's definitely the biggest season finale we've ever had. 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."
How do you think it will all end?
