Ok after watching yesterday's episode I have come to the conclusion that Jai knows that he cares about Bani if not love her (which he hasn't realised as of yet).
HE said that: "Bani ke saath mera ateet juda hai"
I was getting the feeling that Jai-Roshini had an accident which killed their mother. But then it should be affecting all the sisters not only Bani....When he was in love with PIA he was not worried about this PArk Road incident so why with only Bani.
Is it so :
1 As it is only related to Bani and not her other sisters
2 As when he was going around with Pia he had forgotten all about Park road and Roshini's entrance sparked it again in his life.....
