Dynasty (1981)

Season 1: Episode 3

Blake and Krystle finally get married. Blake talks a bit with his son about the homosexuality. There's a big wedding at the mansion, and among the guests are Cecil Colby and his nephew Jeffrey Broderick ""Jeff"" Colby. Cecil is a big oilman like Blake, but he's much bigger, and Blake's company, Denver-Carrington, is just a newsstand compared to Cecil's ColbyCo Oil. Walter blurs into the big wedding, furious about the sabotage on his rig. He and Blake fight about this, and Matthew takes Walter's side in the fight, which leads to Blake firing Matthew.
