Let's think about this...

We are all assuming Asad got raped, why because we saw Tanveer taking off his jacket, Tanveer laying on Asad who is half naked, and the next thing we know we see a precap of Zoya coming and seeing all this. How did Zoya find them? Obviously, Tanveer called Zoya and told her where they were. Wouldn't she want Zoya to think this especially if she wants to prove her win. Of course, Tanveer was NEVER attracted to Asad. Tanveer is ALREADY pregnant, so its not about having an actual baby with Asad. Its only to prove to Zoya she spent the night with Asad. Tanveer could've blackmailed Asad and made him sleep with her somehow, but instead she drugged him so he wouldn't really remember what happened...No Sex!!
