a duplicate of Nandini. Just to make the serial more interesting maybe Ekta has decided to introduce a duplicate just like in Kusum when she brought in Swati a look alike of Kusum. My thought goes in this direction because, it does seem that the woman playing Nandini did try to attract attention of Karan and then very mysterioulsy dispaperared. This whole thing could be a plot by Meera. She could have planted Abir and now a lookalike of Nandini just to make Karan mad. She may play this eyes pyes game for quiet some time just to drive Karan mad.
The woman shown in the party was looking very happy, suave and also young.
