5. Monster's Ball

Complete story — includes the ending

Elena tries to move on after the revelation of Bonnie's death. Damon and Jeremy develop a plan to return Bonnie to the living by using Silas who is trying to make himself mortal and commit a suicide; a life for a life. But the only way they could bring back Bonnie is by killing Stefan, that's what Silas' offer is. After a public meal Nadia reveals to Katherine that she is responsible for her mother's death in Paris when Klaus' minions came for her. Katherine attacks Nadia in the restaurant and escapes. At the Monster's Ball, Damon kills Stefan to temporarily restore psychic powers to Silas in order to get in Qetsiyah's mind and find the location of a supernatural marker. Believing that Silas is Stefan, Qetsiyah dance with Silas and once his powers are restored he compels Qetsiyah to reveal where the marker is. Qetsiyah divulges that she doesn't know the location of the marker, as the Travelers hid it after they killed her and move it constantly, she is instead looking for an amulet that amplifies her powers. Stefan revives from his most recent snapped-neck and snaps Damon's neck, rushing to save Qetsiyah from Silas. Retaliating, Qetsiyah crushes Silas' heart, though it won't kill him, it will cause him to rot from the inside out. A tense conversation with Wes and Elena ends with him telling her to pack her bags, drop out of school and return to Mystic Falls, stating that they won't see each other again. Nadia shocks Katherine by telling her that Katherine did in fact killed her mother when she became a vampire as Nadia is Katherine's daughter. With revenge on his mind, Tyler decides to go after Klaus and ends his relationship with Caroline, seemingly for good, in the process. Damon and Elena use Katherine to bring Silas back as a witch, but despite being drained of blood, Katherine revives.
