It took Sable a while, but it appears that she has finally accepted that Jason and Frankie will be married. When Sable finally signs the divorce agreement, she gives Jason some friendly advice - wait to marry Frankie. Frankie will hurt Jason (and she does).
For some reason, Frankie, always the glutton for punishment, seeks to move on with the sister whose husband she stole. Sable, rightly, will not let Frankie off the hook. Frankie should forever feel guilt for what she is doing. At least this time Sable is a bit more subdued but her message is just as lethal. Frankie will never be able to replace Sable in Jason’s heart or home.
A part of Frankie should know that, but she is determined to move forward anyway, but she will not get Sable’s forgiveness. Beacham is perfect in this scene as she tones down her dramatics except at the right moments. Meanwhile, Ross looks afraid for her life, like Beacham is going to jump her at any moment - and who would blame Beacham/Sable if she did.
