With the sixth season for Archer coming out in January, a few of the stars have talked about what fans could expect with the return of these character. But a guest star talks about what they can also expect from a sister of one of the main characters.

Archer To Be In Hiding At The Beginning Of Season 6?

Alison Tolman, who recently starred in FX's Fargo, is doing a guest spot on Archer as Pam's sister, Edie, who will be showing up for an episode. The actress spoke with Uproxx last week and said that this character may be worse than Pam.

"As terrible as Pam is, Edie is far, far worse. She's a terrible, terrible person," Tolman said.

"Which we could have guessed because Pam talks about her sister like she's awful, but my boyfriend and I were speculating that what if we meet Edie and she's actually delightful and no one can understand why Pam hates her so much? But then that's not the case. She's awful. She is really, really awful."

The plot device that will reunite the Poovey sisters is Edie's upcoming wedding, which results in Pam returning home to Poovey Farms.

There aren't too much else on who will also show up in the next Archer season, but creator Adam Reed has said that he hopes to bring in a host of other guest stars to create crazy characters for the show.

Tolman has been on a hot streak as of late after her turn in Fargo earned her an Emmy nomination.

Archer Season 6 is expected to come out in January 2015.
