Complete story — includes the ending
After much denial, Elena realizes that Jeremy is truly dead. Bonnie agrees to help Shane by killing twelve more people to get the proper magic needed to break the veil between this realm and where all supernatural beings go when they die. If this veil is broken successfully, every supernatural being that has died will come back to life. Also, with the veil broken, Silas will no longer be trapped on the otherside when he dies, thus finally being able to be reunited with his true love. When Bonnie tells everyone about her plans, they all tell her it is a terrible idea. Caroline tries to reach Tyler but is unsuccessful. Matt has a hard time with Jeremy's death. Rebekah leaves Vaughn to die in a cave after he warns her that no one is safe from Silas. Damon makes Elena shut off her humanity because the pain of losing Jeremy is too much for her. After she flips the switch, Elena burns down the Gilbert house as a cover story for Jeremy's death. Disguised as Shane, Silas returns to Mystic Falls with the group.
