Ekta knows where the USP of her show lies....that is the JB relationship....and she will never mess with that. Even if she does show Jai falling for Pia again this will short lived......firstly he will nevre get her pregnant (coz that goes against the very character and personality of Jai Wali) and secondly he will realise that what he has and always had for pia was just an infatuation (and this might just be the turning point for him where he realises that all were infatuations till now but what he has for bani is true love so he will go and propose to her).
Ofcourse that whole nurse and pushkar angle has been brought in to create some misunderstandings between pia-pushkar and jai-bani, but that will be short-lived. They will all separate for a short while. The KS team needs to create some storyline until this unfolding of the park road raaz happens.....so they have brought in these misunderstandings.......just time pass types.....to fill in the weeks.
But when bani does unfold the park road raaz she will be back at walia house and then the love story will truly begin with all the confessions and all....until something else happens😕
Ofcourse roshini has been brought in again coz now the real truth behind park road has to unfold. So we all knwo now that jai did not kill bani's mum.
Pia will never get pregnant with jai......it jsut cant happen.....either she will try to seduce jai (after separating from pushkar) or she will come to knwo how much jai loves bani and will team up with rano to get bani an jai together.
It is also true that now pushkar will recognize the man and aditya will get caught...who he is trying to harm is not clear....jai or bani or the kid or all of them......but when he does get recognised by pushkar, bani will be the first to know and will realise that there is more to park road than what was told to her (infact more than what was even known to jai) and she will want to go back to walia house to be the same old detective she always was.
