I thought Davina was actually going to make Klaus turn into a wolf. I'm disappointed that she didn't - I want to see that.
I feel like Rebekah never really has a clear goal and changes loyalties a lot. I see no reason why Davina should trust her (I noticed she seems to have forgotten she interrogated Katie found out she was in love with Thierry and suggested that Thierry be set-up so that Katie would use magic to save him - her and Klaus worked together on that plan). She goes back and forth - at least with Klaus & Marcel it seems like their goals are at least clear and generally don't change a whole lot.
