I loved Billu's performance today. He did not jump off the seat immediately, but at the right time, with right stuff and right thinking.
Also, A knew all the down grade games M played and she has to be behind bars. Still, in one second, he changed his stand and married her and agrees with her low level accusations.
As Bitblue said, this is not the right time for J to get married to A. Their life would have been a disaster, even if J went down and explained all that A wanted. A can say 1000000000 words about forgetting, but he can not. What does he mean when he says "hum phir se pyar karenge"? Means, in one instant love died and next instant it will be born, based on J's answer. Means, he has conveyed his message to J that at that moment, he is not loving her!
One thing for sure, A & M can never be happy together.
