The Golden Girls/Guess Who's Coming to the Wedding?
From The TV IV
Dorothy's daughter, Kate, arrives to tell them that she is going to the Bahamas to get married. Dorothy wants to hold the wedding at the house but Kate wants her father and Dorothy's ex, Stan, to walk her down the aisle but Dorothy doesn't want him there. They had not spoken since he left her for a younger woman after 30 years of marriage and Dorothy is still (naturally) furious about it. After some persuading from her friends, Dorothy reluctantly agrees to let him be there. She then takes the opportunity to confront him about the way he had left her.
