Rakhi's sudden praise for Carol is the effect of Carol's niceness towards her.
After watching tonight's episode I am disappointed that Rakhi indeed maligned Rahul Roy. That was not a thing to joke about on a national TV. She should apologize for that and I still think that it was a very cheap thing to say about someone.
Maya I had written the exact same words earlier today in some post which has now drowned, but it was just sad..... I honestly fail to understand what goes on in her mind when she thinks of such jokes
