Surrogacy mystery to be revealed

I feel they have been dragging the surrogacy track too much by.now. it has been more than a month since they got seperated. This is too much! If this continues for more than a week or so, I am sure they are going to loose alot of viewers. Seriously there are many errors in the current story . The fake precap which they showed on friday showing dadi getting to know that the baby wasn't raghavs was one among them. Seriously they fooled us all! This isnt fair. They kept us eagerly waiting for that episode. Moreover why cant naina just reaveal the truth now? What is stopping her? Also, rehan had told naina when she gave money for the patent, if she had sold her organ or something so why cant he relate all this and figure out naina is the surrogate? And why now if dadi turns against naina I am sure this show is going to end up a disaster! There is too much negativity and misunderstandings in the show.if only the surrogacy track would unfold soon!
