For me, this all boils down to how horrible Beth is. She really was gloating about Lu's situation and just couldn't wait to be cruel. She makes me so uneasy whenever she is on the screen. She chooses her target and is unmerciful.
I never thought I could dislike a housewife more than Brandi, but Beth is worse in my opinion.
The rumor that she might not come back? She will be back, how else will any of the women on the show will be able to function without her opinion?
