Virat has to slowly but surely acknowledge Sai as a great mother. He accused her of being a bad mother, bad wife...(only a good doctor).
Mazaa aayega if Sai disproves him without meaning to. At this point, she is not trying to prove anything to anyone. Such a good stage to be in.
I don't know how she will prove she is a good wife or was a good wife. We can see it. He was his best with her. But he needs to realise it. (Before that of course, he needs to realise the huge blunder he made by choosing Pakhi over Sai and marrying her.)
He is such a dunce though, is he ever to going to realise it? SAVI he realised so slowly what it meant.
