what i think is going to happen in virrudh next is that somehow shush's mom and vasu are related maybe mothe daughter that's why when she found out that vasu is dherendar's daughter that y she might have said no to vasu and shusant's realtionship.
uattra and dherendar might have had a past togeather ????? which is causing uattra to say no to vasu and shushant relationship
