Look, the thing is clear. One, dynamics have changed. There are two aspects at the beginning, one is Virat and Samrat, the other is Pakhi and Samrat.
Virat and Samrat seem to be shown distanced, and so are Samrat and Pakhi. And it seems as you said, he is handing over Pakhi's responsibility to Virat, which is I guess, okay don't hit me, maybe responsibilty to provide love. But, if we see, Sai is not shown anywhere till here, so this is something which only is amidst them. This is one part of story, which had entangled Samrat, Pakhi and Virat. Cuz this is what Samrat knows, his part of truth. The story till Samrakhi wedding.
And then comes Sai, the true love, the true farz, the only zimmedari. Pakhi now seems expecting again, but Virat no more is in that phase, which Samrat is in, things have changed drastically. There are many additions, and deletion happened in the story. So, it's a discovery, of separating himself from this handed over zimmedari by Samrat, and then moving over to his actual zimmedari in true sense, that is Sai.
So, it's I guess the gradual detanglement from Vaada
This was my reply, do hit me chappals if this seems weird🤣
