As Rose succumbs to the effects of the bite, Damon stakes her in a glorious dream they share, giving her a peaceful death. Uncle John returns to Mystic Falls and comes as an unpleasant surprise to Elena, Damon, Jenna, and Alaric. John reveals to Damon that the only way to kill an Original is with a dagger dipped in white ash wood. A boy named Luka settle in the town with his father ( they are both warlocks ) and reveals that they are working for Elijah because Klaus has his sister Greta and they want him ( Luka ) dead as well. Luka becomes friends with Bonnie and tells her that Klaus will be weakened by the sacrificial ritual, meaning that Elena has to die so that Elijah can kill him and free his sister. John gives Damon the special dagger to kill Elijah. Elena finds out that if a vampire uses the dagger, that vampire will die. Stefan warns Damon and Alaric stabs Elijah, but he pulls the dagger out and tells Elena their deal is off. Elena stabs herself in the stomach, and Elijah begs her to let him heal her. She stabs him with the dagger and leaves it in him. Elijah 's death means that Katherine is no longer compelled to stay in the tomb. She helps kill the Martin witches. When Isobel returns to town, Katherine double - crosses the Salvatores by kidnapping Elena and stealing the moonstone for Klaus in exchange for her freedom. But it is revealed that Klaus wanted Katherine and compelled Isobel to get her and the moonstone. Klaus enters Alaric 's body and compels Katherine to stay in Alaric 's house. Bonnie and Jeremy find the site of the a witch massacre and Bonnie channels all the power. Alaric / Klaus blends with Stefan, Damon, and Elena and finds out that Bonnie has her powers. Damon tells Bonnie to put on a protection spell and make Alaric / Klaus believe that she is dead. Elena does not want Bonnie to die, so she pulls the dagger out of Elijah 's heart. After Elijah comes to life, Elena learns the full history of Klaus. The Aztec curse is fake and there is a curse on Klaus, as he is a vampire born in a werewolf bloodline. There is a ritual that involves killing a vampire and a werewolf and a Petrova doppelganger, that will unearth the werewolf side of Klaus making him a hybrid. Elena realizes that the real curse is on Klaus, who therefore wants to kill her. But Elijah says he has an elixir that can save Elena from dying. Elena believes Elijah, but Damon says that there is another way to save her life and feeds her his blood. Stefan tries to stop him, but he stabs in the chest with the wooden dagger. Elena then cries that she will be a vampire against her will. Maddox kidnaps Tyler and Caroline. Damon frees them and is bitten. Then he goes to Klaus to tell him that he does not have a werewolf and witch, as he killed Maddox. Klaus says that he has backups. Klaus takes Elena from Stefan. Elena sees Jenna, who thinks she is dead, but Greta tells her she is transitioning. Damon asks Katherine about the vampire, and she says that Jenna is the backup vampire. He then checks his arm and sees that Tyler has bitten him. In the season 's finale, Klaus is working on the ritual out in the woods and is near completion when he is about to kill Elena, but Stefan tries to work a deal with him. Klaus agrees to have Stefan work for him in exchange for Damon 's protection. Elena is `` killed '' in the ritual but is shown to have survived. Regardless, Klaus 's werewolf side is unleashed and he becomes the first hybrid, half vampire half werewolf. Bonnie arrives and subdues Klaus with her powers, giving Elijah the opportunity to strike, but Klaus talks him down offering to help find their siblings. Elena 's survival is revealed as John had Bonnie cast a spell that had him die in Elena 's place. The next morning John succumbs and dies. At his funeral, Elena reads a note from John saying he will always love her and she will always be his daughter, even if she becomes a vampire. Damon also shows where he was bitten and walks away. Reception Ken Tucker of Entertainment Weekly wrote, `` The throbbing red heart of The Vampire Diaries remains the tension between Damon and Paul Wesley 's Stefan, and their mutual attraction to whomever Dobrev is embodying at the time. '' Mark A. Perigard of the Boston Herald said, `` The triangle -- quadrangle ? -- becomes more twisted by episode 's end. It leads to shocking violence against outsiders that deepens the tragedy and the mythology at the core of the show. `` Game on '' just might be the two most chilling words uttered this season. '' Matt Roush of TV Guide commented, `` The Vampire Diaries is the sort of show where ' never say die ' is written into the mythology -- a good thing for several of the opening hour 's apparent victims. I do n't know how much longer The Vampire Diaries can keep churning stories at this feverish rate, but if this is your sort of guilty pleasure, you 'd be crazy not to bite.
