I believe that Asad being the person he is will not go after Zoya unless he himself is sure that he is not at fault.
So here is what I think is gonna happen. Zoya leaves for Ajmer heartbroken.Then everybody would find out what really happened. Asad realizes that trusting Tannu instead of Zoya was his biggest mistake and leaves for Ajmer to win her back and Tanveer having failed in her plan would go after Zoya to kill her. Tanveer finds Zoya first and confronts saying Why does Asad love Zoya and Blah! blah! blah! and pushes her off the cliff. Asad saves Zoya brings her back home.
I am ok even if the whole truth is not revealed, i just want everybody to know Asad was out of his senses and he was tricked. CV's still can bring Tanveer back for baby daddy track. But again this is my imagination to bring back Asad's Pride and self-respect which makes him AAK and to bring back Zoya's honor with Asad's redemption for not trusting her in the first place. We never know what CV"s are upto.
Had to write this to get some peace of mind.
