In one of the olvs Rhea is seen entering the party with some documents which might prove that Ananya is Avni.
Well after what Avni will be doing for Sweta, the least Sweta can do is to stop Rhea from disclosing Avni's identity and create scene in the party. One of the reasons Sweta loathes Avni is that Bebe accepted Avni as bahu while even after so many years she hold grudges against Sweta.Now with Bebe accepting Sweta giving her blessings that too due to Avni's efforts, but Sweta's attitude still remaining unchanged towards Avni will make this anniversary track purposeless. I am not expecting Sweta to suddenly become all goody goody towards Avni because again that will be difficult to digest. But atleast she can stop plotting and interfering in AvNeil's lives when both of them are happy with each other.
