It seems now that Prathna is completely trapped. The Thakrals are trying to put into Akshay's head that the motive of her kidnapping was something else, and it seems like he's believing it. So what will she do now? Her life is practically in danger living with the Thakrals.
I think she should leave and open up to someone who will listen, like Gyan or Siddhi.. and she should leave soon b4 its too late.
