Was it his own decision or prompted by Vasu? Had I not seen yesterday's episode I would have definitely said it was the later but since he was there to witness some of the taunts the neighbours and Davaker were throwing at Thapki and her family, I hope it was his own decision. I hope he made the decision to be there for Thapki's family in which ever capacity he can, realizing how it was his fault they are in this mess in the first place.
So do you think we will see some conversation or recall of a conversation between Bihaan and Thapki while Thapki and company are gone to the mandir which will be the reason he takes this action or will he make this decision all on his own, with zero input from Vasu...
