Elena with no humanity was great fun to watch, even though at the same time I was worried she was going to do something unforgivable. Also, I know she has no feelings now, but don't you think she was a little too evil all things considered? She's a completely different person. Well, we'll see how this turns out.
Staroline were just so cute in this episode!! I'm so glad they have so many scenes in S4!
Still not sure about Klaus and Hayley, their hook up seemed a little forced to me, even though they look good together and maybe with a proper storyline they could be an interesting couple.

It was one of the better episodes of the season, definitely.
