Honestly though? Sisters fight, women fight. Women fight with the women that have affairs with their husband. Not only in Dynasty-land. I don't think it unthinkable that Sable could have snapped and got into a physical fight with her sister. Just as in that first cat fight between Krystle and Alexis in Dynasty season 2. Frankie had been baiting and goading Sable for a long time. It's all about context and reason. Sure them ripping each others clothes off in the foyer for no real reason would have been stupid. It depends on how and why it's done. But it's nice of you to tell me I don't know the Sable of The Colbys. Next time you see her give her my regards.
