Correct me if I m wrong but...
1. Wasn't Anita announced as antagonist? Or were they all assumptions...2. In all her earlier interviews Survi kept saying Bela is a simple girl from village without any mention of being naagin...Now here she is a naagrani...What I mean to say is Does not matter what they say...They r not supposed to say anything specific...And they r trying to do things different this season so maybe that's why all this suspense abt main characters...And I think we can all see even if Vish is not totally bad..She is grey..Has ulterior motive...I don't think she is one of the main villeins...In fact I think there r many different parties not just one main evil...But the way Vish keeps forcing Bela to kill Mahir..I mean there are others on their hit list too...Kill them first then come back to Mahir...It will give her time to brain wash Bela back to revenge mode...But No...She is like obsessed with Bela killing Mahir... Desperate to see him dead...It is not normal...Kuch to jhol hai apni "loyal" friend Vish mein...But does not mean she will turn full nasty villein like shesha... Maybe she will be grey
