I was thinking about the same thing.
There are so many clues, talks about next janam, being a woman next time, and on and on.
Even Simran is very happy, only problem in Astitva are Astha and Kiran.
Well well well, so Abhi is about to do the twin act or shall I say father-son act. What will Simran's reaction be? What about Abhi's parents? Ohh no what about Astha I and Ashta II?
