I'm on catchup as been away. I saw Rosemary upset at his joking digs, cos thats what it is.
I didn't like his meaness at first but now I see him as a typical comedian who makes fun of folks. If Rosemary was happy with her body she wouldn't take umbridge with him but obviously she's not, hence her coming in the jungle I would think. So she should agree with him silently.
I would say to Eric, as he was stood there topless, "I think we should club up and get you some bras". If he can dish it out then he will take it surely.
