I do not believe for a minute that Suraiya and Zubair will be successful in their plans. Just look at them tonight, his first attempt failed miserably after Aaliya told him not to be a kabab mein haddi and Zain took his wife away for privacy. Then there is Suraiya who revealed to Usman she was upto no good. In a holy month like Ramadan, there is no way evil will win over good.
As for Rehan getting the card, maybe he will get to the bottom of this and expose Zubair for what he really is. During the first half of this episode I thought okay Zubair is doing all this reluctantly because Suraiya has her eyes on him but I was wrong. The way he entered ZaYa's room, the satisfaction on his face thinking he'd be successful breaking his cousins marriage just so he can have his freedom proves just how selfish he is. Aaliya went through so much for him and this is how he repays her, he deserves the karma coming his way.
