Complete story — includes the ending
It is revealed that when Matt rang the bell eleven times and Cade came to Mystic Falls, Kai was able to as well, but only halfway, so he enlists Damon and Alaric's help to bring him back fully in exchange for him waking up Elena. Matt and Caroline learn that everyone Stefan ever compelled are now remembering things they've forgotten. This includes Dorian, who abducts Stefan and explains that he now recalls Stefan murdering his family back when Stefan was being forced to work for Klaus. Dorian shoots Stefan, but then regrets it and tries to get him to a hospital. Cade comes to Stefan during an out of body state as a result of him dying and tells Stefan that Caroline would be better off without him. In the hospital, Stefan breaks up with Caroline and tells her that he is leaving Mystic Falls. Bonnie finds out that she has psychic powers and tries to contact Enzo. She does with Cade's help and learns that like when Cade created hell, she created a place where Enzo's spirit now resides. Alaric brings the girls to see Caroline and tells her that they have lost control of their powers. Cade learns Kai escaped from hell and Damon tries to convince him that he can only be fully redeemed and saved from Cade if he brings back Elena. They go to her casket where Kai stabs Damon, tells him that he doesn't believe in redemption, and escapes with Elena while Damon falls to the floor, desiccating.
