I've always gotten the picture.
I've never been a fan of B2. Especially the twins.
As for Sera, I only watch her when Ginger or Mila are with her and 95% of the time I'm not watching her then either.
I have to say I'm not exactly excited about B3 and the twins being there right now.
I doubt anything really good would happen between Mila, Ginger and Sera but as long as the others are there you can pretty much guarantee NOTHING will happen.
