Thanks to Sable, Krystle learns that the body that turned up at the lake was none other than Roger Grimes - the man Blake had a run in with many years ago. No wonder Alexis is resuming her attacks on Blake. Krystle will not allow Alexis to get away with it. But, really what can Krystle do - she has a brain condition that can kill her.
That does not stop Krystle from making one final threat to Alexis. After breaking a fancy vase, Krystle holds a book to Alexis’s throat and warns her that she could kill her and no jury will ever convict her. How many times has poor Alexis had someone literally at her throat?
Ultimately, Krystle’s threat is hollow and Alexis knows it. Krystle will not be around long enough to stop Alexis. Good thing Sable had promised to do that for her.
Two parts of this scene are hilarious. When Krystle asks Alexis what she is doing, and Alexis responds with a reference to drinking champagne. And then there is when Alexis offers to take care of Krystle if worse came to worse. When Krystle tells Alexis that she is the last person to take care of Krystina, Alexis makes one of her many snarky remarks that she perfected in Season 9.
