None of us are quite sure why there is such a need for Razia to get her daughter married to Ayaan. Even Siddiqui is not pushing it to the extent she is...evidently Razia knows something that even her husband is not aware. As evil as Razia using her daughter as a pawn, the woman does love her daughter as we saw when she feared losing her when Tanveer poisoned her.
I would be interested in the inner conflict and turmoil a daughter would face to learn that her mother was deceptive but even more interested to find out how the tables will turn on Babi Bi when Humeira finds out that she sold the jewelry to make her mother look bad. That would an interesting twist to the story line.
Tanveer and her have a past - but what is their tie to each other? How did they meet? I think that this story line is definitely worth exploring. I do not think that these characters are leaving the show anytime soon. However, I do hope that at least Zoya starts to catch on that nothing is all that it seems to be with Tanveer.
