Why they are showing Asad so weak?

When Tanveer called Asad, she was talking to him as if she is a winner and Asad is behaving as if he islooser, he has done something wrong for which tanveer is taking advantage of, why he was not showing her who is the boss. Here I feel Asad's expression was very thanda, when he was taking to tanvir, specially when she was threatening that she can harm Zoya, the Asad I know would do anything at that moment, but he said very calmly that you wont do anything,there was no anger even in his eyes. I don't understand why he is entertaining her?

i knw
i want him to be akudu n hassena scared of him and so is everyone scared

What makes you think that? he is just a person who is strong on his ground that he will not bend to her, let her do anything and everything he will not leave his path of truth, and that is why he doesnt pay any head to what Billi says, does that makes some one WEAK?

this scene came before Zoya's entry. He is the one who has made Zoya his bhabhi, so he has to bear that. But I feel that he has to strongly face tanveer, all his recent encounters with tanveer is missing the spark which AAK has, just look at the precap, just a thought of Zoya being hurt make him so impulsive that he forget where he is standing and forget all his tameez and everything and hug zoya and give assurance to himself that she is fine.
