I have noticed, especially in tonight's show, that Shabby is using the sofas to assert her status. Perhaps something she learned through acting, but something people would inherently do, is to physically make herself higher than Ben. Ben looked weak as she was then higher than him, and he was standing there leaning on Mario. It was very very clear than Ben was feeling belittled and probably intimidated. I agree with the OP that Ben doesn't seem to handle confrontation very well, but he is the one that keeps putting his foot in it, whether intentionally or not.
This is very interesting to watch, I'd like to see how this develops over time.
I hope Shabby stays, not because I particularly like her, but she's part of a few interesting scenarios in the house.
I'd like Dave to go, personally.
