Move over, Buck, T and Alice.

The latest promo for season two of United States of Tara makes no secret that another alter is on the way.

Take a look at the preview and get excited for the show's return on March 22:

** Update: Creator Diablo Cody says the new alter's name is Shoshanna, and she'll serve as a "mentor" of sorts to Tara's family. She makes her first appearance in the season's fourth episode.
