What if Bani decides not to tell Jai that she is pregnant as part of her hatred towards him...... that could very much be a possibility.
If he does get to know that she is preggy from now only, i think bani (the crackpot twin personality that she is) will misunderstand his love for her thinking that he is doing all this becoz of the baby and not becoz he loves her. Remember when he tells her that he has forgiven pia and pushkar..... her reaction was, mera pyaar apke liye kabhi bandhan nahi banega etc. etc.
Then divorce hearing comes thru, jai is feeling guilty, so he does not hold her back thinking that it is better to let her go becoz she it is she hates him and he wants her to be happy and acc to him her happiness does not lie in being with him. Then finally masi is gone too and when bani is actually all set to leave jai finally confesses his love but of no use.......... (have given up waiting for his so called confession, i don't think it is going to happen in this lifetime atleast).
And then the much awaited/predicted accident happens with him and she has no choice but to come back and nurse him becoz her love for him finally takes over her hatred and maybe she finds out more about the raaz too and realizes that actually jai was never to blame.
This all i am assuming based on the fact that the storyline has been picked up from "too much too soon". since the issue of pia getting back with jai and he getting her preggy is out of the way becoz roshni did not want her role to turn negative, the park road issue has been used to create a wedge bet them. and in the original story too, the lead does leave him once she gets to know about his affair with the sis and she ends up loosing her child too, but then when he is in trouble later on she comes back to help him and then everything is rosy and fine.
so assuming ekta maya is still holding onto the fact that KS is diff from her other soaps (god please please let her keep her word for once), I guess this is the future path the serial has to follow.
any comments/galis are most welcome......... just my two bits.
