i m pretty sure that marriage will definitely happen.
in the vo it is clearly said that the lives of swara- sanskaar and ragini-laksh are going to be united and more over laksh will reveal his real face or intentions only after the marriage of swasan so shaadi will happen.
and then vo said but taqdeer has some other plans and this aashiyana will break. so that means some one from the mm or gadodia house is gonna die.
since swara and sanskaar are standing at the pyre and the pyre was shown from the havan kund of mandap i guess some one who can effect their relation will be dead. and i guess it will be none other than kavita or it might be even ragini.
even kavita's death cant impact much on swasan relation and moreover when she herself backed out from shaadi. even if swasan are in guilt mode that cant go for long so it cant be kavita.
i believe it is gonna be ragini as that can effect swasan on bigger terms. we can see swara fighting for ragini's death and sanskaar standing by laksh. and i guess in between this we have kavita trying to come between swasan wantedly or unwantedly and finally we will have ragini back as it will be planned by kaveri. when she was sent to jail kaveri clearly had hatred for ragini for using her and getting the status but not saving her from the police. so kaveri might choose to kidnap ragini and stage her death and then we have swasan relation at tiff kavita's plotting and finally ragini's redemption realising her mistakes which she did.
if properly this is gonna be an awesome track and we will have a lot of drama and more of swasan. apart from all of this i just want swasan to get married and then they can bring any stupid twist into the show.
knowing the kanjoos nature of ph i dont think they will break the wedding at the last after spending much money on all the rasams of the shaadi. this formula is only used by ekta and only she can do that.
waiting for swasan marriage and cute moments between them before marriage.
