Zainab is behaving like a naive fool, I am sorry to say. The police officer asked if anyone has threatened Shehroz, leaving everything aside, Sufiyaan has threatened Shehroz and they have to tell the police that, the rest is upto the police to find out whether Sufiyaan is guilty or not. Beyond that there is no need for Zainab to do anything. Leave it to the cops and take care of your family. I like that Shehroz and Ushna's relationship is pretty clear at this point, she even told him about Sufiyaan stalking her. Naima is reacting like a lioness whose cub has been threatened, good for her, Zainab is too bloody emotional even now about her useless brothers.
Despite everything I like how Shehroz and Ushna's is being developed, they are attracted to another and they clear any issues then and there between them as both are pretty blunt and straight-forward, the conflict between them is going to be taking sides between Naima and Zainab, hopefully that gets resolved pretty quick too.
