Because the Night

Damon is looking for Katherine to get the cure. Damon thinks that Elena is oblivious to that fact, but she is actually trying to get to the cure as well. When Rebekah also shows up in New York, she's impressed with Elena's secret agenda of getting the cure. Flashbacks reveal Damon's hedonistic life in the underground club scene and a complicated encounter with Lexi, where Lexi tried to get Damon to flip the switch like she did with Stefan before. Damon also briefs Elena with his experience with Lexi in New York and tries to convince her to flip the switch as well. Meanwhile, Caroline and Stefan try to convince Klaus that it would be in his own best interest to help them track down Silas. They team up and try to figure out Silas's next move. They find out that the last massacre has to be involved with witches. Silas is still trying to convince Bonnie to do the last massacre. Bonnie is hesitant, but Silas reminds her that when the third massacre is performed, all supernatural creatures that died come back to life. So Bonnie decides to perform the massacre. Stefan, Klaus and Caroline look for the location and find it. The twelve witches try to save Bonnie from the use of dark magic, but they find out Silas has control of her. So they try to kill her with a knife, but Caroline takes the knife and stabs the witch who is connected with eleven other witches. All twelve witches die, completing the massacre and Bonnie faints. While in New York, Elena attempts to take away a paper Damon found to track down Katherine. She tries to grab it while seducing him, but Damon catches her by revealing he used the same trick. He confides that it took a while but he finally got Lexi to let her guard down and re-enforced the door and locked her outside in daylight. Lexi has no choice, but to hide in the shade. So Damon runs away and confesses that he felt guilty after and still does. But while talking, Rebekah breaks his neck and they take the paper and go. Bonnie wakes up and her memory after the cave is gone. Silas bribes Klaus to help him, threatening to kill him with a white-oak stake he stole from Rebekah. Elena and Rebekah steal Damon's car and search for Katherine.
