There are some very important facts to be remembered in Jai-Bani-Roshni and Kiran quandrangle!
The Letter that Kiran addressed to Jai was only meant for Bani and not for Pia and Rano...they are all sisters and do not share that huge an age gap, why did Kiran address Jai's letter only for Bani and not to anyone else!
Why did Nishikant call Bani seperately when he was in his Death Bed and tell her to take Jai Walia's help...why didn't he call all the three sisters?
Why did Nishikant take a promise or Kasam from Bani that whatever happens in the future, she will always be there for her sisters? If Bani is their biological sister, then why did Nishikant have to emphasise so much on Bani taking care of Pia and Rano?
Jai accusations on Nishikant's character...Jai is not the types who will shoot off his mouth, whatever he talked about Nishikant being a gambler and an alcoholic seemed to be bang on, as if he knew a blow by blow account of Nishikant's life, remember he even mentioned the loan amount that Nishikant had taken from Mohan Khandelwal, again Jai's best friend. How on Earth did Jai know Nishikant Dixit so well, a man whom he had never met before?
Jai and Kiran might have been very close friends, but they were surely not in the same age group...Jai specifically mentioned to Aditya that Kiran was a few years older than him...and Roshni seems to be a few years younger than Jai....is it possible that Kiran and Roshni were cousins and their common connection became Jai.....if Kiran and Jai were not friends, because of their age difference, then the only way they could know one another was through Roshni who was Jai's girlfriend at that time....and Jai being admiring of Kiran would have stuck an unusual friendship with Kiran which would have led to her trusting Jai with her daughter when she died...Jai does seem to have that kind of aura, which makes other people trust him blindly!
Whatever relationship Jai shared with Kiran, one thing is for sure, that he seemed to hate Nishikant and kind of holds him responsible for Kiran's state of affairs...since Jai assumes that Kiran was unhappy in her marriage!
The way Roshni looks at Bani seems to indicate some sort of a deep bond between them...Roshni is both jealous and yet strangely affectionate towards Bani!
Whatever is the case, the secret is only between Jai and Roshni and no one, not even Jigyasa have any inlking about Bani's connection to Jai and Roshni's past!
