i think this is what happened...7 years ago ..jignesh got a girl pregnant and arjun found out about it and jignesh did not wanna help the girl and left her so just to save his brother in law arjun gave the child his name last name and told the girl to tell the doctors and everyone that he's the father of the kid so rashi never finds out and even if she does ever find out she thinks its arjuns son.. and why i think that is it because when dadi opened the drawer in the cupboard she said that arohi can't open this because that is one proof that can get them divorced and prove that arjun's a bad husband!! and yea plus rudra and kumud dont know about this only dadi and arjun do..
tell me what you people think about this prediction?
