'Defiance' Season Finale Sneak Peek: What In The World Is Irisa Up To? (VIDEO)

The second season of "Defiance" comes to a close on Thursday, and if you think Irisa will be at the center of what goes down, you're right.

As the season heads into the home stretch, Irisa, the daughter of Lawkeeper Joshua Nolan (Grant Bowler), is enemy number one. Nolan has to pull out all the stops to keep things from spinning out of control, not just for his family but for New York as well (let's just say that Irisa -- who has not quite been herself this season -- has plans for the city). As you can see from HuffPost TV's exclusive clip, Nolan will have his work cut out for him. Irisa's powers are literally out of this world.

Elsewhere in the town of Defiance, Pilar McCawley (guest star Linda Hamilton), becomes even more unstable, and the McCawley family ends up in serious danger.

If the awesome special effects in this clip are anything to go by, fans of "Defiance" should be in for one hell of Season 2 finale. And hey, Syfy, don't wait too long to renew this excellent show for a third season -- please?

The two-hour "Defiance" Season 2 finale airs 8 p.m. ET Thursday on Syfy.
