The conflicting emotions alone are enough to torture us until it returns in the fall. Elena tells Damon that even though Stefan will be there she will still love him. Stefan breaks the news that Maria is dead and Julian, who is angry and determined to make someone pay, lashes out and rips Stefan's heart out killing him. Even after killing Silas, Stefan has some trouble remembering everything that happened the past summer. At an emotional gathering to ring the bell for Bonnie, she is able to speak to her friends with Jeremy relaying her words. Aaron shoots Damon while Elena is taken away and meets Enzo, who is still locked up after all these years.
Luke shows up in Liv's dorm room, revealing they have ulterior motives behind everything Liv already knows magic and Luke wasn't being compelled. Caroline stays with him to comfort him. Damon comes up with a plan where they will offer to exchange Aaron to save Elena; if Wes doesn't give them Elena back they will kill Aaron. Bonnie is concerned as the destruction of the Other Side might affect her and her friends. Meanwhile, Caroline overhears Katherine and Stefan having sex.
Elena calls Damon while they are both trapped, but he doesn't tell her. She then fails to go to the other side and goes to hell instead. Katherine comes up with the perfect idea that can help Stefan move on from his fear from the safe: Katherine got into the safe with him. She finds out the truth about Stefan and temporarily drops out of college to go look for him. Bonnie cannot hold on for long and she falls, with Stefan catching her; and he passes through. Wes escapes his bonds and captures Damon. To prove his point, he uses Julian Tyler , to show her what will happen to any supernatural creature if they try to enter the town.
Stefan, Caroline, and Enzo go to see the Travelers who have the antidote for Damon's virus and are working on one for Elena's. It's silly to get angry at a show for axing a character you liked; that person is fictional, he or she is there to serve a story and it may be in the best interests of that story for the person to die. Elena reads her diary that Katherine wrote in and hallucinates Stefan with Katherine and stopping him from doing anything else. In the meantime, Enzo takes Bonnie to meet the traveler Silas who will teach them the spell, but he will only help if they will bring him back to life as too. Qetsiyah performs a spell on Stefan, connecting him to Silas and ridding Silas of his psychic powers. With revenge on his mind, Tyler decides to go after Klaus and ends his relationship with Caroline, seemingly for good, in the process. Later, when Stefan tries to comfort a dejected Caroline, their conversation leads to them figuring out Katherine has taken over Elena's body.
Silas makes apearence in Mystic Falls and confronts Damon. Elena and Caroline head off to Whitmore for their fun filled freshman. Matt and Jeremy find the gas line, break it to cause the leak and they leave. Katherine realizes that she was wrong about Stefan and decides to accept the deal, but just when she does she collapses. Jeremy runs to find her while Alaric finds Elena crying over Damon and hugs her. Caroline reveals to Katherine posing as Elena that she slept with Klaus, which Tyler overhears and becomes extremely angry and hurt. Elena, Damon and Sheriff Forbes find Stefan's safe, but instead of Stefan, they find a dead body, meaning Stefan was very hungry and could have turned off his humanity.
Elena tries desperately to find Liv so she can start the spell again, but Bonnie tells her that it is too late and Elena collapses. Bonnie finally tells Jeremy what it means to be the Anchor to the Other Side. While Markos and Damon have little chat, Markos stops the visions. When Elena tells Damon that she had a dream about Stefan in a bar, Katherine says she had them too. Aaron confronts Elena about his family's deaths, and Damon reveals that as a part of his revenge, he killed all of the Whitmore family except one, preferring to wait for more generations to be born so he could continue his revenge. Her first instinct is to call Damon but at the same time, Damon is trying to figure out how to tell Elena that he killed Aaron and also infected with the same virus. Damon explains that for his plan to bring everybody's loved ones back, they will have to kill many travelers so they can pass through Bonnie and their friends can pass through her to come back, like Markos did.
Stefan explains they had to lock her in her dorm after she'd been infected by the virus. Katherine then asks Nadia to search information about Enzo and who he is so she compels Matt but Tyler overhears it. Qetsiyah has Stefan hostage and tells her version of how Silas became immortal. Caroline and Enzo volunteer to do what the Travelers want and kill the other doppelgänger, because they only want one alive. Enzo and Caroline follow a lead to a witch named Hazel, but Enzo kills her.
Wes enlists the Travelers to set a trap to keep Enzo and Damon trapped in a house until Damon has to feed on Enzo. Katherine tries to run, but she's stabbed and killed with the traveler's knife by Stefan. Meanwhile, 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 Stefan and Elena captured by Markos and being drained of blood, their saviour comes from an unlikely source. Markos suspects something, so Liz stays for a drink to convince him nothing is happening.
The Cary Brothers - Run Away. When Elena is trapped by Wes in a cage she meets Damon, who tells her about The Whittemore family and how he survived. Liv chants a resurrection spell after her brother has his neck snapped by Caroline, and meanwhile, Matt and Jeremy cause a gas leak under the Mystic Grill. Damon risking a half-sacrifice was impressive, but I was most touched by his willingness to stick around to help Sheriff Forbes, who has always been a friend to him. After Nadia leads them, Elena and Stefan are trapped in a house full of travelers who are doing an unknown ritual.
