I've not watched previous seasons completed,, but I've watched enough to say that human Elena sucks and vampire Elena rocks. At least what we got to see a glimpse in this episode. I really hope that writes take advantage of that, and not use the possible "cure" for her.
It would be nice to see the cure take effect in other character, but Elena is just too obvious "victim" for that to make any difference. So any other and I would die to see Elena discovering more to her new vampire world.
I'm really not a shipper either but episode give me a pretty good idea what ship to sail on,if I want to. Definitely Damon and Elena are made for each other if you ask me. I mean, judging by this episode.
And I really liked the part where Elena was really having fun (and feeding at same time). That's what I want to see in future episodes, not beating herself up about what happened.
