According to TV Line Michael Ausiello, Elena won’t be getting revenge on Rebekah in season 4, but Damon will do it for her and it’s not Rebekah he goes after.
Question: It’s maybe a little too early to ask this, but do you know whether vampire-Elena will be taking some kind of revenge on Rebekah for causing her death when The Vampire Diariesreturns? —Gabriela
Ausiello: I’m going to assume Elena has her hands full completing her transition to vampire. One person who does have revenge on the brain is Damon, who blames poor Matt for Elena’s little predicament.
