Okay,here is what I think happened
Jai passed out cause he had too much to drink, in the same fashion as he did when he hugged Bani officially for the first time after their marriage.
Pia, too lost consciousness cause she suffered a concussion on her empty first floor.
Pia has not seen the CD that Jigs has, so may be she is assuming that something happened between Jai and her.The pictures only reveal their hugging and Jai getting up in the same bed as her but nothing more.
Pia may remember the part where Jai and she hugged but nothing more and is simply playing on them.
Medically it is impossible for a woman to get pregnant at first attempt post operation.(Doctors confirmed this)
Get the wild horses of your imagination running and come out woth excuses to save Munna.
BTW, Who do you believe is more guilty of ONS.I say Pia,not because we all love to hate her or that our fondness for Jai rendered us blind to his faluts but because JW was technically divorced and Pia was still very much married, regardless of the fact that J and B loved each other or not.But we all know, it did not mattered to her cause at first she harped that B does not love Jai and then she changed her stance telling Jai he does not love Bani.
