Yes don't worry, Zoya is his fiance in front of the world even though its fake! Dilshad would not pick Tanveer randomly when it risks Zoya's visa, she would rather pick Zoya to marry her son due to the vow she took in front of Shireen!Second of all, if she does it to save Tanveer's honour, think about it what honour would she have left if Dilshad finds out about her pregnany? I'm sure she wouldn't force her son into such relationships. Moreover, i have full faith Dilshad is not the type of mother to believe her son would do something like that if Tannu claims it's his! Soo relax, don't overwork your mind, it'll give you a headache like me :( LOOOL just relax and watch it unfold, I for one am looking forward to the shirt scene! ;)
