Her behaviour with all housemates, abusive language and especially the use of word "kanjari" or "prostitute" for Shweta who is Salman's favourite must have pissed him off completely.
So there is a good chance Sallubhai must have given Dolly enough dose off the record, chasten her completely to apologise on TV and in general not act funny anymore. If it wasnt for Salman, I have a serious doubt a character like Dolly would act so timid and apologetic on TV. She is not the type who would regret worst of her actions. It was only Salman thrashing off the records. Dolly did try to hide her Salman recommendation when she tried to say that Salman did not even know she was on BB.
Just my views.
