This is proving to be quite the season of guest-star goodies for The Good Wife viewers! After being endlessly praised by fans and critics for her hilariously terrific performance as Elsbeth Tascioni two weeks ago, TVLINE has announced that Carrie Preston will be reprising her role at some point this season. Details have yet to be released as to what it is that brings her back. Any guesses?

Along with her return, we have Michael J. Fox, who will be coming back to play Louis Canning and who will be butting heads with Good Wife newcomer, Jennifer Carpenter (Dexter). Carpenter, who is known as one of TV’s biggest potty-mouths with her role on Dexter, will be playing a saint-like University professor, the complete opposite of what we’re used to.

Catch an all-new episode of The Good Wife on Sunday at 9/8c on CBS.
