We have enough in the form of ever quarrelling Ishwari and Bijoy. They spice up things.
Dev asserting his rights and Sona asserting herself by holding his shirt. They are so close physically but so far mentally. What chemistry! Quarrelling couples have more chemistry, it seems. The way they exert their rights over each other!
Vicky has some sense when he said that Sona is not interested in getting back and so she did not show her daughter for all the years.
