It Seems NO REMARRIAGE...because based on OLV, there is a function(white kurta and red jacket for Neil) and a party (white suit for Neil with black and gold dresses for others) but no REMARRIAGE like mehndi, haldi and marriage etc.
I was looking forward for re-marriage of AvNeil and some light hearted moments with celebration...
I think they will be two functions, one Neil in pink sherwani and Avni in off shoulder dress,and the other in the party sequence, it's ok for now if they are not going for elaborate re wedding, as the chances of groom swap or any twist would happen , in this party we know whatever will happen will be at the end of it not before that
