The fate of Donna Gable will always hang over Kevin Can Wait. Erinn Hayes played Donna, the wife of Kevin James' Kevin, in the show's first season, but her character was killed off ahead of season 2 in favor of a reunion with James' King of Queens co-star Leah Remini. Many fans were upset to see her written off so unceremoniously.

There was never any clear reason given for Donna's death, although some have shared elaborate theories suggesting that she was murdered. James said that the decision to kill off the character had nothing to do with Hayes as an actress, and was instead because they were "literally just running out of ideas" with Kevin's family so happy and stable.

The move ultimately backfired, with fans rejecting the changes to the show. CBS Entertainment president Kelly Kahl admitted that the change had something to do with the show's cancellation, saying, "The show made a choice at the beginning of this year, we agreed to go along with it, and unfortunately the audience did not respond to it." Now that's some real #JusticeForDonna.
