Desperate Housewives

Desperate Housewives will welcome back a former cast member on the May 13 series finale.

As first reported by TV Line, Dana Delany will reprise the role of Katherine Mayfair on the soap's final episode, although it's unknown at this time what brings her back to town.

Delany exited following season six of Desperate Housewives (and currently stars on Body of Proof) after taking off with girlfriend Robin, portrayed by Julie Benz (who is NOT expected to appear on the upcoming finale).
