At the end of that scene when she asked him if his anger was gone, he couldn't even manage a smile. Same thing when she asked him to smile later on, it didn't reach his eyes but when he smiled at Babita it did. I wonder what was going through his mind at that moment. He looked so hurt, and she knew it.
Yeah so true..
Even I had this thought... His smile did reach his eyes while sindoor daan and during grih pravesh... But when Minni asked him to. Smile he did smile but was not a content smile... He don't expect this shock coming to him and when it came he was totally broken...
May be he don't want to show his hurt and pain to Babita bcoz he may want to be haply that now Babita is his wife... And he want to at least live that moment happily...
