Hey guys,
I know there have been alot of guesses as to what the secret Jai is trying to hide is. But I just couldn't stop myself from sharing my thoughts with you guys.
I think the secret has to do with Bani most. Jai seems only worried about Bani to find out the secret and not her 2 sisters. So I don't think Jai and Roshini r involved in the death of Bani's mother. There must be something else going on. I think maybe her real parents died on park road due to a car accident caused by mr. Dixit. His wife, Jai and Roshini were also there. Since he caused the accident he felt guilty and so he and his wife decided to adopt the little orphan Bani and raise her.
