Complete story — includes the ending
Now that he got his memories back Stefan is on a mission to kill Silas so he could get his revenge. Katherine realizes she is dying from having the cure taken from her. When Bonnie meets Amara, Amara shows that she can both see and touch her which she explains is because she is the anchor to the other side. Damon and Elena realize that the only way they could get Bonnie back is by turning her as the anchor to the other side. That's why Damon goes to Qetsiyah and ask if she can do the spell. Qetsiyah reveals that the only way the spell can be done is by getting Amara with Elena and Katherine together and getting a drop of their blood. Katherine tells Qetsiyah that she will give her blood only if Qetsiyah helps her stop Katherine from aging, which Qetsiyah agrees. When Qetsiyah starts the spell, Silas shows up. Qetsiyah is wounded and Amara is taken by Stefan to lure Silas. Before Silas can kill her, Stefan stops him and kills him. Amara stabs and kills herself. Qetsiyah is able to return Bonnie and make her the anchor and then decides to kill herself. As she passes over to the Other Side, she reveals to Bonnie that by being the anchor, she will feel every death of every supernatural. Nadia tries to get on with Katherine who doesn't want to have anything to do with her.
