I believe Ishwar thinks He has been through alot [ U know ] Now that He is under the same roof He will see , Kashayaps life was not that EASY as he believed . I want him to see What Panna went through when Rounak left , What Dadaji went through , What Alok really did for BM - Kids . I want him to see all the sacrifices Everyone made , While He was Busy Flying in SKY .Moment He sees All this , He will b ashamed to barge in like that . That is the only Way . REMORSE for Actions. He needs to realize how He has stolen Happiness from the Family .
