There is posh and then there was Jaqueline but she would have married the devil himself if it meant she got more stripes in the cartel. A rotten egg like Denault would have been clawed into in no time and eventually Jacqueline became the chief anyway.
Jacqueline bumps into Angela in the winery, (a scene from season 2, 1982 - '83):
Jacqueline approaches Angela about burying the hatchet.
Jacqueline: "....The point is you're in business with my son."
Angela: "Well that's his problem and also his choice. Not mine!"
Jacqueline: "Nor mine but Chase is not about to leave Falcon Crest and that is something we both have to live with."
Angela: "You're suggesting we settle our differences, for Chase's sake?"
Jacqueline: "And for ours."
Angela: "Perhaps a truce would be in the best interests of all concerned."
