I don't think Davina is really gone, or at least I hope not. At first I did not care for her, but I slowly grew to like Davina and Josh. Josh won me over with his goofiness and I loved the LOTR quote. I hope they use this story to make Davina a "normal" witch because giving a character too much power means you have to kill them eventually, and I have really come to buy the Marcel/Davina dynamic. He really thinks of her as his family and those two are great in scenes together.
Poor Rebecca just stinks at love. The only person she has been involved with that did not die or dump on her is Matt. I do like that she is trying to get the ladies together and stop them from being used. She is more kick butt on the Originals, but she is still the same insecure person. I root for her though because I swear she just wants to grow old with someone and drive a Prius.
I want to know how Celeste was able to body jump or what have you. I need an explanation.
I took it that Papa Tunde just wanted to give Celeste a fighting chance at mowing down Klaus. His family was gone and his time was past, but he was more than ready to do whatever it took to put a hurting on Klaus.
I like that the Marcel and Klaus relationship is so complex. It can't be easy to betray the man that raised your, even if he is an epic (insert insulting comment here).
On TVD I am sticking around for Katherine. I just love the character.
