As previously detailed, there will be a fourth alter on season two of United States of Tara.

Her name will be Shoshana and she'll serve as a "mentor of sorts," according to creator Diablo Cody.

But that's not the only change coming to this Showtime hit, which returns on March 22. Tara will also interact with her alters like never before.

Get a glimpse at what we mean in the extended second season promo below.
