Complete story — includes the ending

Elijah confronts her and reveals he knows she lied. He then leaves Elena in a cave. Meanwhile, Bonnie and her mother, Abby, find themselves playing a part in a ritual to appease the spirits of nature (by killing all the Original vampires with a spell requiring 2 generations of Bennett witches). Rebekah keeps Elena in the cave as Elijah goes to Stefan and Damon. Elijah tells them they can either stop Esther from completing the ritual by killing either Bonnie or Abby or Rebekah kills Elena. This they turn to Meredith and Alaric for help in killing Kol which ends up dagger the others linked to him. Elena escapes from Rebekah's watch and hides in the cave where no vampires can enter. Klaus finds out about the ritual as well. Rebekah tries to set Elena on fire but Elena reasons with her before she can. Klaus, Elijah, and Kol find Esther and Finn about to complete the ritual. Damon and Stefan find Bonnie and Abby and decide the only solution is for Damon to turn Abby, thus preventing her to be a witch anymore. Stefan reveals he has not had human blood since he almost drove Elena off the bridge. Elijah writes Elena a letter of apology and realizes they are not as good as they think they are. Kol flees, Elijah says he is leaving, and Esther and Finn have fled their family. Rebekah realizes the White Oak tree is still out there. Alaric wakes to find weapons and case files and Meredith shoots him.
