Elijah | Katherine
It doesn't really bother me. The first version of her that was here was the person who sort of explained everything to me. She was also one of the best students in my class.
As long as she stays away from Kol and doesn't provoke Rebekah, I have no issue with her. I already know she's not stupid enough to bother you, and I know you'll stay away from her.
Besides, it makes Caroline happy, and right now, I won't deny that girl anything.
