Brilliant post dear... I have thought each n every minute detail in so much depth...
ur post is definitely giving answers to the various things happening..
1stly why only Gudiya factory to kill Zainab n fire it?? Haider said kuch aur bhi hua tha, so Raziya played ek teer se teen nishan, 1.killing Zainab, 2. got a reason to make Rashid do whatever she wants 3. Something that related to Gudiya destroying of factory which would cause the owner loss.
2nd. Haider helping Humaira is something i didnt understand, may be bcoz he is flown over her innocence but then he would just spare her from his revenge but here he trying to help her out, n dat sorf corner for Hunaira was from evn before he entered Siddiqui mansion..
3rd. Haider knows Rashid is innocent than why would he harm Rashid, may be he didnt want Asad to know about Gudiya factory raaz, bcoz HE wanted to take revenge.. and in HIS way..
It could also be Shirin u told the perfect reason...
4th.. Yes Haider n Zoya must not be bonded by blood.. they must be related with the Gudiya factory raaz,,,
Now its just left to see whether Haider n Asad join hands or would dey play game on their own terms...
