Regarding the Brad/Chad/Jennie question... A lot of their time together was spent VERY close up and if the clear difference in their looks didn't tip her off, she would have been alerted by the body language and touching that accompanied her flirting with Brad - not Chad.
I doubt very much that Bettina wanted to be on the WTA ep so it's no wonder that she said little during the WTA. I'm sure being there is part of the contract she signed or her bitter little butt would have been a no-show. I was appalled that she criticized Brad for not being happy about her family treating him like crap. She made it clear that she was presenting Brad with a false image of herself as a shy, reserved woman and has no right to complain when he wasn't interested in an illusion.
I'm most surprised at the positive comments about Hillary. She is probably one of the most mean-spirited bachettes EVER and yet she is cheered rather than trashed for that. She is even called a good sport for smiling through her embarrassment at being caught in the act of being reprehensible. She tells us that her malicious comments aren't planned, but rather spontaneous bursts of wit - a circumstance which (I guess) absolves her of the need to apologize. Her over the top crying binges are explained away by her strong feelings for a man that she indisputably never actually even listened to. Hillary is a beautiful woman in a noble profession, but I can't think of anything else nice about her. Judging by her behavior on the show I would be very reluctant to want to strike up a friendship with her knowing the likelihood that she would be saying mean things about me behind my back.
