During the earlier episodes we witnessed some wonderful bonding moments between Najma and Zoya but as the story progressed and Asad and Zoya started spending more time together, we lost the chance to see those wonderful comical moments. Now that Tanveer is back in the picture and Asad has no more time for Zoya, who has politely removed herself from Asad's life (and bedroom), so he can be with Tanveer (I know - joota mat mar, I am only the messenger), wouldn't it be great to see Zoya bond with Najma once again.
It would be fun to see these two share moments together such as doing each other's hair make-up, cooking, talking about guys and then, when the whole matter with the court case is resolved he sneaking Najma out of the house to go to the lounge she wanted or to see a guy whom she is interested in...
Somewhere in all of this, the writers need to let Asad know she protected his sister from gundas, kept her secret about her hair at her request etc.
And in all of this, it would be great to see a bond between Najma and Zoya develop so when the truth is revealed about Tanveer and Asad still refuses to consider Zoya as a wife and a bahu for the family, what better than to hear from his own sister's mouth that she wishes she had a sister (or bhabhi) like Zoya.
