Julianna Margulies said that her decision to leave the firm Lockhart/Gardner will spur a "bloodbath," speaking about her character in season 5 of The Good Wife.

Leaving with Cary to start their own firm will unravel a series of dramatic events set to take place in the new season.

"It's going to be a really tumultuous time, I think," Margulies added. "You're going to be on a whirlwind and then there's going to be an explosion. It's going to rock everyone's world on the show."

The show's co-creator, Robert King, stated similar sentiments when he said season 5 will be a "civil war."

In a recent interview with TV Guide Marguiles said that the most important thing to realize will be that her character, Alicia, and Cary (Matt Czuchry) can never be Will (Josh Charles) and Diane (Christine Baranski).

"The uphill battle will constantly be, 'Did I make a mistake?'" she said. "There's going to be a lot of tension and a lot of friction and a lot of heartbreak. Diane and Will will end up feeling, when they find out, like she stabbed them in the back. And she did."

In the same interview, she also suggested that Peter and Alicia will give their marriage another shot.

Here's the official description for the fifth season premiere:

"'How to Begin...' - Alicia must focus on the firm's efforts to prevent the execution of a convicted murderer while she secretly plans her exit from the firm with Cary. Meanwhile, Eli helps Peter assemble his staff in the governor's office, on the fifth season premiere of THE GOOD WIFE, Sunday, Sept. 29 (9:00-10:00 PM, ET/PT) on the CBS Television Network.
