If I recall correctly, one of the original plans for the show was to show how Nikhat loves to dance but is never given the chance to because of Mamujaan and his conservative attitude toward everything. They showed how she got excited a few times at the beginning of the show, but they seem to have dropped it as of late. I'd really like for them to bring it back and build upon it! It would give her a personality outside of what she has and allow her to come outside of the box that she is currently in, where she is defined completely by her marriage to Imran/the comments people make about her skin.
Not sure how to make Noozat a relevant character though. We know she's boy crazy and it says in the original description that she likes fashion- perhaps if they built on that? Or even if they tried to make it so she tries to become friends with Najma, as they are in the same year in college.
I just feel like there's a lot of potential with them that's not being used right now, which is why we've got a topic like the one we have now where people are complaining about how useless the plotline with Rashid's family is.
