Vrinda.
there are the facts that Vrinda's character hasn't had much to do uptil now; whatever character comes in usually has an important part to play for some time, and that Vrinda is a bit too sweet which doesn;t happen in soaps, only the main protagonist is like thtđ.
The thing that really made me believe that the blackmailer is Vrinda is because of the way Saloni gets her instructions. I was awed at the luxurious stationary on which the 'jewellery claden' person delivers the instructions. It made me think that Vrinda is probably a rajkumari of some village or something and since Nahar is also a royalty, she liked Nahar from before but he got married to Saloni or Chandni or wateve, and so now she is back to get revenge. And the whole village people trying to kill Vrinda was a set up, coz come to think of it, how would the villagers knoe where Nahar lives that they reached his house and tried to kill Vrinda? And also why would JiJi or Kakisa deliver their messages in such a "thakur type" way.
What do u guyz think?
