|“||Look, Rebekah, I get that we had our Thelma and Louise thing back when I had my humanity off, but let me make one thing clear — we're not friends.||”|
Rebekah originally resented Elena due to Stefan breaking her heart and betraying her for Elena. She also became enraged when she saw that Elena was wearing her dead mother's necklace and she attacked Elena. Rebekah tried to be civil with Elena and open up to to her about the Original's history until Elena daggered her after getting the information she needed from her. Elena told Klaus about Rebekah's role in the attempt against his life in order to keep her daggered so she wouldn't come after her for daggering her. She began to dislike Elena for daggering her and not showing remorse for her actions. Rebekah tried to kill Elena to take revenge against her for daggering her. Elena started to consider Rebekah as a dangerous enemy for her actions. Elena and her friends continued to berate her for trying to kill Elena. Elena has tried to kill Rebekah and her family on various occasions. In addition, she tried to get her daggered on several occasions by using her weakness of being naive. Elena succeeded in killing her two brothers, Finn and Kol. Elena never felt guilty for killing her brothers or trying to kill her. Elena agreed to help Esther kill her children until Elena figured out that killing an Original would kill their whole bloodline. Rebekah and Elena has tried to kill each other numerous times, Rebekah eventually succeeding and (unintentionally) turned Elena into a vampire. Upon the latter's transition, their mutual enmity escalted to greater lengths, resulting in Elena actually going in towards Rebekah several times for the kill, but as Rebekah is older and also an Original, she typically defeats Elena with ease, furthering the latter's desire to see Rebekah be put down for good. Elena felt like she didn't have to to apologize for her actions against Rebekah even though she believed that Rebekah should feel bad and continuously be reminded of all the times she tried to hurt Elena. They continued their rivalry until Jeremy's death, when Elena turned her humanity off and Rebekah offered her an alliance. Rebekah was there for Elena when everyone turned their back on her. She offered to let Elena stay with her since everyone else couldn't stand Elena when she has no humanity. They worked together to find the cure. Elena also moved in with Rebekah and decided she wanted her to have the cure so helped her pass Elijah's test. Rebekah seemed upset that Damon and Stefan were torturing Elena and stated that she wasn't broken. Once she got her humanity back, Elena told Rebekah that they weren't friends and Rebekah seemed hurt. Despite this, it seems that their once-intense rivalry has cooled down.
