I hate that Jeremy is still seeing Anna and Vicki, I don't completely blame him because it was technically all Bonnie's fault that he sees them in the first place. I hate that she's putting all the blame on him, when her bringing Jeremy back and him seeing ghosts was her consequences. She didn't take any responsibility for her part imo.
I'm on the fence with no humanity Stefan, apart of me likes seeing him like that because he's funny and interesting but another part of me hates it because I love how he was in season 1-2.
I hate how Damon keeps crossing boundaries with Elena and the fact that she's not speaking up on it is very weird.
