The Vampire Diaries fans should remember the Gemini Coven, which now includes Jozie and Lizzie as members, since Uncle Kai failed to kill them when he killed his pregnant sister.
Putting the pieces together, it sounds like the twins may be forced to undergo The Merge, a Gemini coven tradition used to select the new leader.
Julie Plec recently dragged Kai Parker’s name into the Caroline mystery, reminding fans that the twins are related to nasty Uncle Kai by blood, since he’s their biological mother’s twin brother.
