My two cents on this track:...
I fell the girl ( Vai's friend) is just a distraction like Sudha was in previous track......I mean why would she go to such extreme as if she knows how.things work between the kids/ Purvi or Vir/Purvi????
As for Vaibhav, he may be a spoilt rich brat, but he is not devious enough for such games...that too, involving kids!! As far as he is concerned, he has won the bet and that's the end of his concern.....also he is confident that his words as a favourite son of the house carries more weight than a molkki bride.... So he is not bothered by Purvi complaining to Vir...
I think it's Anjali who's the mastermind behind all this..... When Vir figured out it is Purvi who has kidnapped the kids by the CCTV footage, everyone else was shocked but Anjali just had a smirk on her face......she was not surprised at all.....I think when Jyoti pointed out Priyu screaming, Anjali would have peeked in and made the video.
She knows exactly which buttons to push for Vir to hate Purvi and separate them. But though the rape truth will be out, the identity of blackmailer will not be revealed as Anjali has to continue as the Gillian for some more time....
