The Last Day

Elijah tells Elena that the way to break the curse involves sacrificing a vampire and a werewolf. Maddox injures Carol Lockwood to make Tyler return to town, after which he and Greta kidnap Caroline and Tyler. Damon forces Elena to drink his blood so she will "survive" the sacrifice. Alaric returns as himself and gives the message from Klaus that the ritual will happen that night. Jenna forgives him. Damon realizes that if Klaus doesn't have a werewolf, he will be unable to complete the ritual, and Elena will have another month. He rescues Caroline and Tyler from the tomb and kills Maddox. Klaus takes Elena from the boarding house to begin the ritual. Damon informs Klaus that he has rescued the vampire and werewolf he needs for the ritual, but Klaus says he has backups. At the site of the ritual, Elena realizes that Klaus has turned Jenna and is using her as the vampire. Katherine makes Damon aware of a wolf bite he got from Tyler during his transformation.
