Zoya did not taje her clothes with her and in Ajmer she is wearing her normal clothes, So I guess they wil meet before Ajmer. It may be like this:
Asad sees her, somehow convinces to come back home, or just to meet Dilshad once.. For Dilshad Zoya wil say yes, and when Zoya will be in Khan house Tanveer will play pregnancy card.. Again zoya gets upset, she will decide to go back to New York.. But before going back forever she wil want to visit Ajmer once.. She will leave for Ajmer.. She will tel Dilshad and Najma that she is going forever this time but she will ignore Asad and wont inform him.. Asad gets to know Zoya left and going to NY, he just wants to meet her last time so he runs to Ajmer.. Billi all furious, will go behind Asad..
