I see tomorrow having one of these two scenes which could force the nikaahnamma signing:
1. AsYa get married when Gaffur walks in taunting and insulting Asad for marrying a married woman. Thus, pissing Asad off and insisting Zoe sign. Zoe of course will sign because she wants to prove her pure and innocent love (excuse me while i barf)
2. In true hindi movie fashion the SM members will stop the wedding just as these two are about to say QH.
