'Good Wife' Bad Guy Returns

Thanks to its revolving door of judges, defendants and plaintiffs, The Good Wife has introduced countless recurring characters, but Colin Sweeney -- played to creepy perfection by Dylan Baker -- is easily the most memorable.

He was last seen at the end of season one, after being sent to prison following the suspicious death of his stalker/lover, but Sunday's episode brings Sweeney back into the fold when Alicia Florrick is forced to do the unthinkable: ask him for a favor!

Check out an exclusive sneak peek of Sunday's new episode, titled Marthas and Catilins, airing at 9 p.m. on CBS!
