I don't think vishal didnt not ever unaware where his role would be gone in future. He definitely talked frankly with ph regarding the shape of his role in this show. So i dont think there is anything left to talk about this whenever actor himself is ok with his character. Immj is always suspense filled drama & I feel to maker ;this drama's main suspense & charm was always vansh rai Singhania from beginning hence they probably kept vansh role in concealment in initial promos. 1st promo was very simple that was shown 2 persons are in love but this is not immj ever . As already one of my forum mate wrote here that ph of this drama spent cost & energy on vansh role to establish it properly to audiences so if vansh role would be mera a 2nd male lead then why they would give this huge effort on vansh role. Just simple answer ,to cvs vansh role was always trump card to make immj successful. & maker of immj has indeed succeeded to cast rahul as vansh role.
