When they told the story of the weapon being a "cure", I had to pause the show and think of things. I enjoy seeing the other side of Elena and the possibility that because her feeling are heightened, that she'd be honest and admit to herself that she actually does love Damon. If Elena goes back to being human, the story would go on a loop when they had to protect her from Klaus making her into a blood bank.
What I really enjoyed about this episode is that it was about Rebekah, that she was indeed capable of love and that she is lonely because she has no one. This is one of their best episode. Kudos.
