Zoya, you're smarter than this!

So if Asad / Tanu spoilers prove to be true, I don't understand why Zoya will believe what she sees. I mean, knowing what she knows about Tanveer, PLUS all of Billu's threats, WHY will she think Asad is at fault? If cvs are really going through with this cheap track, the only saving grace would be if Zoya stands by her man and exposes cat-woman for what she is.
