I don't understand how the track wld work if asad does not marry zoya... Because if asad gets married to Tanveer in the next 10 days then zoya will again be visaless and she will have to leave the country right away... Se won't have any time to even consider marrying Ayaan so quickly... And Dilshaad has also said that asad will get married by next Jhumma or Friday leaving absolutely no room for Ayyan and Zoya track... Ayaan is not even finalized yet...
In my prediction I think there will be issues no doubt but asad and zoya will have to get married for story sake.. Otherwise noting will make sense... Even if GUl proceeds with Ayaan and zoya contract marriage it will be too quick and too hard for fans to digest.
I just can't see any other way except for asad zoya marriage at this time
