I actually am for getting the girls off of the show but I'm on the other side of the fence, I'd rather have Bela gone that Ruby. Ruby's story is much more entwined with the brothers story. What about Bela? Aside from (and I quote Jaye on this) "being a thieving bitch woopdeedoo" I would say she's one disposable character. Unless, Kripke is planning something huge for her, if yes, please make it soon because I'm horrified on every episode that she's on.
I don't get the point as well to have that sex scene other than make us drool more because agressive and sexy Sammy is the way to be! Anyway, just my two cents.
