What I feel is that the deal part wont break anupre but pregnancy track will.
Bajaj has a trump card that no one knows except prerna.
He will show anurag that prerna is the mother of his child and has shared the news with him and not anurag.
Every father has a right to know about his childs existence but prerna hiding the same will lead her to more trouble.
Lack of communication is their problem since beginning.
