At the end of Season 8, Krystle starts suffering from migraines - just like Fallon at the end of Season 4. Unlike with Fallon, we actually learn why Krystle is suffering from these headaches. (The Colbys explained why Fallon had amnesia, but never really explained why she was suffering from headaches and how they miraculously disappeared.) Krystle has some sort of brain condition (Artery to Vein Malformation to be exact) caused by the riding accident that Alexis is responsible for. So, not only did Alexis kill Krystle’s unborn child, she pretty much sentenced Krystle to an earlier death.
So, the best part of Krystle's headaches is that it causes her to do weird things like running off to Dayton for no reason. Is there ever a reason to go to Dayton? Further, she was suspected of murder for some time. But, lovely Krystle can never be a murderer. She can toss a mean plate though. Blake holds a dinner for some of his major donors following his failed gubernatorial bid and Krystle switches into strange mode.
For some reason, Krystle takes all the dinner plates, and stands in the hallway as she tosses them down the hall - maybe trying to hit the Grecian statue at the end of the hall. Regardless, the scene is some campy fun - totally over the top. And kudos to the look on Linda Evans’ face while doing it. Was she try to play the part or was she thinking, “I can’t believe the writers are making me do this?” We will never know.
