During HM, V was busy n Vinu s thoughts and didn't realise that P kissed him.
Now also he's busy Vinu s thoughts and if Sai will do the Pooja or not. So he would not have registered much of what Mohit told i guess.
He won't act much on that even though he heard it. Now he's focussed only on Sai not knowing Vinu s truth.
Makers could have added a line for Virat of how she managed Savi s delivery alone.
