Actually,at the beginnin I loved Davina but now she is trying to kill Klaus so I don't like her.

I hate her more than I have ever hated any tv character. Second is Elijah I'm really starting to dislike him. I LOVE the rest especially Rebekah, Davina, Cami and Klaus.

or Marcel, don't hate them, just don't like them that much

with davina repeatedly trying to kill klaus....give it up already!!
she's more like an annoying bee buzzing around klaus' ear at the moment than a formidable foe unlike Mikael, Esther and Finn presently are more a thorn in his side (and the rest of the family) the sooner Davina joins Team Klaus the better

Marcel is a close second but I really hate Hayley. It's a pity they wrote off Rebecca and kept boring Hayley.

Hayley sucks. Like the rest, though

I love Hayley!

To be honest, I don;t really see a point of her character.
