Didn't Tanveer say she was Married?

So, Zoya should point out to Asad that Tanveer is already married and he cannot marry her. This way Tanveer would have dug her own grave bcoz she is the one who told them her husband was hunting her and wanted to harm her. And Zoya could play along and say that we will help with the baby and this way they can still get married and Asad would not have to marry Tanveer.

You're right. It would make sense. But I won't count on it cause CVs seem to forget the obvious when it comes to the ladli Tannu.
