Walter was last seen in the 2013 episode “Defending Your Wife” as Haskell’s (Wayne Knight) ex-wife Margo. In Season 4, Haskell is determined to stop paying Margo alimony, so he pushes for her to finally set a date to marry her new fiance. But — drama! — after spending some time with Margo, Haskell realizes that he’s still in love with her.
The back half of Season 4 will also see several other guest stars, including Leah Remini returning as Stuart’s (David Alan Basche) sister Nicki, David Faustino (“Married With Children”), Georff PIerson (“Unhappily Ever Ever”), John Kapelos (“The Breakfast Club”) and Lou Ferrigno Jr., son of original “Incredible Hulk” Lou Ferrigno Sr.
The TV Land hit also stars two-time “Third Rock from the Sun” Emmy winner Kristen Johnston, Donald Faison (“Scrubs”) and Kelly Stables (“Two and a Half Men,” “Greek”).
“The Exes” does not have a return date set as of now.
