Pia might have said that it is Roshini that is danger to Bani's marriage but I can bet that it is going to be Pia. She would soon realise what she could have got and instead Bani got it...She would realise that Pushkar can never give her all that she want from life...
It is going to be Pia that wopould come between Jai and Bani. And then it is going tobe Dadi-Mausi-Jigs husband who would teach and ask Bani to stand upto her sisters and do not take everything lying down just to make her sister happy.
