"Burn Notice" airs its season finale tonight and, according to Jeffrey Donovan, who plays burned spy Michael Westen, he goes to never-before-seen depths of pain -- but he also gets to meet the guy who burned him!

"He's going to have answers that only will satisfy people halfway; dealing anytime with any kind of covert organization they can't ever spill the beans totally," Jeffrey says. "But what you're going to see in the finale is pretty exciting because, even though Michael does find out who burns him, it doesn't release him from the perils of his career choice."

As this new character enters into Michael's life, Carla (Tricia Helfer), who has made his life so difficult this season, will exit.

"Without giving too much away, the eventual outcome was necessary," Jeffrey says. "What's going to happen is that she has powers above her that control her and she basically relies on Michael to save her butt at the end. And he tries, but it doesn't go as well as expected for her."

Fiona (Gabrielle Anwar) is one woman who will be staying in Michael's life, although the couple, who did hook up for one night only this season, still won't be resolving any of their relationship issues when the show returns.

"We have great chemistry," Jeffrey admits. "We love exploring the push/pull attraction that we have for one another. But I think that season three, you'll probably see more of Michael and Fiona trying not to be together; really, really just trying to find out maybe if there's someone else. Maybe there's someone else out there that we can fall for and can give us the love that the other person can't."

The "Burn Notice" finale airs tonight at 10 p.m. on USA Network.
