Because pronita got the keys. now b4 moving to usa jigz will make sure some big amount of money is stolen from the locker and..all blames will be on Pronita.
Added to that it might also be possible jigz has told rano and Pia to act so with pronita. Because if you notice Rano-Pia said Pronita today to do whatever they tell her to take revenge.
So.. based on the lack of emotion portrayed in the reunion scene and Balaji creative's "creativity" its highly possible that above stated might happen which would mean fall in TRP.
BUT, keeping the recent dispute of Balaji and Star plus in mind, certainly it wont be wise for Ekta to jeopardize KS's TRP now!
what do you think ppl?
