If the upcoming track comes with revealing a past like this, I won't be surprised. And I don't want to blame Shireen for marrying Rashid because I don't think she has that brain for realizing anything so easily. The pain of Rashid can always be felt that how hurt he feels to leave a sweet wife like Dilshad who was always there to support him, a strong and self-confident son like Asad on whom he could always be reliable, and a cute daughter like Najma who can fulfill all the happiness of this family with her cute activities. There can be nobody to leave a family like this. There are some restrictions from the mamaji for that Rashid is not even allowed to meet with them. Rashid's mother is also aware of these all, but she is also helpless like him.
I think Zoya will connect her own past as well while helping Rashid to patch him up with Dilshad, though i know it's not an easy thing for Rashid-Dilshad to be together again before everything gets revealed. btw Zoya still is not aware about his second marriage. If she comes to know about this, she will come up with a good advice to him which will be helpful for both Dilshad and Shireen.
I know that right now Rashid is being blamed for all his activities, but we should understand his feelings. He has become confused thinking that what to do with his life after meeting with his past again after 17 years.
