My prediction.....!!!!

As we have found out that Vayu's father is alive, what if Vayu's father saved Mayank and he's alive, but in a coma or paralysed. Vayu's father must have then told Vayu everything about Nitya and to what lengths she can go to. Thats why Vayu has come to get revenge....!!!!

Cause when Vayu tells Nitya who he is, he tells her that the phone call about him and his dad dead in an accident was a lie. His father did that so he could keep Vayu away from Nitya. He never mentions that his father is dead. Well during that conversation....!!!!
