New reports hint at Martindale's character playing something of an opponent to Eli Gold (Alan Cumming). As showrunners Robert and Michelle King weighed in on the nature of this new character, they revealed that her dynamics will be played out against Eli.

"Every year we look for a character and an actor who can go toe-to-toe with Eli Gold and make him blink," they said in a statement. "So we were thrilled when Margo Martindale agreed to play Willa Eastman. Her ability to mix comedy and drama is unparalleled. And we can't wait to see how Margo and Alan deal with each other."

The description for Willa's character reveals that she will be one tough cookie for Eli. She has been described as a "campaign operative responsible for past successes by underdog presidential candidates in Iowa who hides her intelligence and cunning under a fake, folksy charm."

The next chapter of the legal drama is set to premiere on CBS on Sunday, Oct. 4 at 9 p.m.

The season 6 finale, entitled 'Wanna Partner?' aired on CBS on May 10.
