I understand there's some enmity between DC and Tandons but I'm unable to decipher what it is about. If DC is Sunil's first wife's son then why is his surname Chawla? Or was his mom having an affair with Sunil and maybe that's why Dimple keeps on saying she hates characterless women? Or is there something else? Sunil mentioned after the engagement fiasco that it has to do with Vishwas. So, is Vishwas their illegitimate son and Dhruv their son?
