Could Ella Greenaway Return For Season 11?

The clip -- which was exclusively released by TVLine -- reveals that the case that will be taken up in the first episode of the next chapter will be "so twisted" and "bizarre" that it will take a "brand new mind" to help solve it. Aisha Tyler is introduced as the new character who will bring the expertise to crack this case.

"I've studied these men after they were caught, now I want to catch them," she says.

Recently stills featuring Tyler's character, Dr. Tara Lewis, a forensic psychologist, were revealed exclusively to Entertainment Weekly, and the lady we're used to on The Talk has gotten a dramatic makeover for the show. She has gotten rid of the lustrous hair for a short hassle-free crop, and is all decked out in office wear suitable for the BAU.

Speaking to the publication, Tyler talked about her character's detail in the team.

"The people in the BAU are analyzing these unknown subjects trying to catch them, but my character analyzes them after they've been caught to make sure they're competent to stand trial," Tyler said.

She went on to reveald how she "wanted her [Dr. Lewis] to look really different than how I look on The Talk."

"It's great because I get to do field work, I get to run around, wear a vest, wear a gun," she added. "She's someone who has gathered a lot of evidence about the psychological makeup of the sociopath and she's now bringing that knowledge into the field to help catch bad guys."

Season 11 will premiere on Sept. 30 on CBS.
