I think tanveer is going to expose infornt of Asad in maha sangham, but there is twist beacause of NIkihit. tanveer will surely use it as she is going to witness beautiful relationship between brother and sister. he willblackmail asad about imran and will ask him to marry her to save NIkhat marriage.
as i remember in one episode asad tell ayan that a brother can do anything for his sister happiness. he very well know that NIkhat love Imran and also if her relationship with imran broken then it will be painful for her. so he will agree, marriage will not happen but before that ajmer track might be happen. where Asya will get some clue fromdivine invention and also dilshaad will come to know about tanveer's pregancy and other things. she might will tell ZOya and ZOya will seek help of Ayan. eventually they will hbe cometo know that Imran is father of tanveer,s child and this time NIkhat will break relationship with imran.
at end Asya will be together with following tracks.
I do not think asad willever leave zoya because of Gaffure being her father that does not suit his charachter and also we can see it clearly that asad share beautiful relaitionship with ayan and NIKhat. the major reason for rashaid and dilshaad sepration was Shreein not gaffure. so he do not bring that thind in their relationship.so i donot think it going to ever sepration beacause of gaffure
