what is moti ben's problem

i thought her hatred towards santu is because she is choti jaat and all that stuff. Then why is she being nice towards khemi all of sudden. arent she santu the same jaat? and she wasnt this nice to her when she and hiten wanted to get married. Why did she suddenly change her tune?
