The only one I am unhappy about is Elijah. I believe he would have gone to see her if he knew she was dying. The ending they had in "American Gothic" was not enough. To have his scene a hallucination was not good.
I am a big Klaroline fan so having that scene with Klaus and Caroline was epic! And Caroline saying she got lost in the woods while pulling leaves out her hair was hilarious.
I loved the connections with the title "Let Her Go". So many levels. Letting go of Katherine after so long. Having the song "Let Her Go" in it by Passenger. Hint hint, nudge nudge, wink wink, say no more. And then maybe a bit tenuous the hook up between Klaus and Caroline. Since there was a Klaroline fan video ages ago to the same song.
