We know Aditya Hooda what he is capable of. Zoya will not fall ie accept love in one week's time. So to stop her, he can go to any extent. Neither groom swapping ll happen as he is from different religion nor he can force her for Phere. Even she will not be a runaway bride this time or sign legal marriage documents even on gun point.. Zoya n Adi marriage will be legal only under special marriage act. Adi ll get Zoya's sign on registered marriage papers by hook or crook...History ll work as time machine.Drama started with Divorce papers.it will take backward turn gain to past with Legal Marriage papers.Exploring all past incidents n getting answers. Time will come when Abu Siddiqui will realize if Zoya chose one wrong person, doesn't mean her choice Adi is also wrong.
PS. He has reached Zosh again to activate his plan n I think to stop her he will use same formula. When she was going back to Masuri n Arjun brought legal papers to declare bankruptcy. He stopped her from taking decision. He will do same again to stop her from marriage unwillingly
