I guess Zoya was right here!
"...Unka jab bas chale mera tumse nikaah kara den...jab bas chale mujhe yahan chod ke chalen jaaye aur phir lene bhi na aaye.."
Don't think she was being stupid or childish in saying this.
The receptionist told her that Asad was attending a meeting,when he was supposed to be their at the Chowk to recieve her. She did go to Khan Mansion but it was all locked. How is she supposed to think sensibly when anger and disappointment were taking the better of her? She wasn't angry for nothing!
Why should she behave the way people expect her to when these very people have wronged her?
Ofcourse, it wasn't Asad's fault that he got late but then Zoya didn't know this. Had she known she would have rushed to the police station.
If Asad can make wrong decisions in emotionally weak moments so can Zoya. Her anger was justified.
