It seems that the creatives are trying to set the scene for a Pia and Jai to get married. (don't kill me for saying this!! I don't want it to happen either).
Pia said to Pushkar that now that I am pregnant we have to get married (meaning she wants to marry the man whos baby she is carrying!!) and then Jigs tells her that its Jai's. Meaning she will probably make Jai marry her as well... and Bani (becuase she is so Saintly) will tell Jai to play along, because if he doesn't Pia will suffer even further, and probably in order to save her sister she will 'marry' Tarun (As she now knows that he loves her). I'm just guessing that this is how the story will continue. But then again you never know!
Just wanted to know what your guys thougts are?
