I don't know but I feel today's episode was a bit confusing or running in loops for some reason. I mean, some reason was disclosed regarding Khanak & Diwakar not receiving support from Diwakar's paternal aunts who were taunting/gossiping on the side.
Shyamlal has some affection or bonding with Urmila but there seems to be a link in the past for some reason as to why Khanak wanted to get out of the party, restricting her father towards further involvement with Urmila etc.
I feel the reason might have to do with perhaps Urmila might've helped in the past but Dinesh might've taunted Urmila for doing so, leaving Khanak & Diwakar under the loop. Again, this is just a prediction based off when Urmila lended money to Shyamlal for Manu's tenthouse set up. But, Dinesh seems to have a habit of berating Urmila for this henceforth the speculated animosity.
