@Nish- Nice post, quite topical,with impending SaHil wedding,Rehan's character has to develop.
I would like to see Rehan stay positive and disown Billi in the end,like she disowned him at birth.
I hope he'll be Sanam's ally in fighting Bili and Ahil's blind love for his murderous Mummy.
He can develop beintaa mohabat for Sehar or Asma and live happily ever after.
