Esther uses Matt to push Vicki over to the human side so that she can kill Elena and stop Klaus from creating more hybrids. As Bonnie sends Vicki away before she can kill Elena, Esther breaks open the door to the other side, allowing any ghost with unfinished business to cross it.
Esther invited Elena to the ball they were throwing and Elena wanted to know what she wants with her. Esther told Elena that she wants to link her children so that if one is killed, they will all die. She used Elena's blood which she put in a champagne that her children drank. Esther also burned sage so no one else would hear their conversation.
Esther brings Elena to Alaric, where she tells her she's planning on turning Alaric into an Original just like Mikael as the vampire to end all vampires. During the ritual, Elena refuses to give Esther any of her blood, saying that she will have to kill her to get it. Esther forces Elena's blood into the vile. Elena tells Esther that in wanting to undo the evil she created, she turned Alaric evil just as well. Esther says Alaric will be nothing like her children and she explains that she wants a world where Elena and her loved ones shall not suffer at the hands of vampires anymore. Elena later discovers that Esther linked her life to Alaric's so that he only has a human lifetime to fulfil his quest.
- Esther: (to Elena) "I love my family, Elena, but they are abominations. I betrayed nature when I created them. It's my duty to kill them."
