Heres what i believe will happen:
Mukti is sitting in front of the mirror getting ready to be married. Flashbacks are shown of her and Prem. She cries while "Kabhi na sukoon aya" is playing in the background. She walks to the mandap. Kul is sitting there with the flowers hanging over his face, so you can't see his face. All the while flashbacks of her and Prem are being shown while the saat pheres are taking place and when Kul puts sindoor on her, the violin version with all the drums of kabhie na sukoon aya is playing all the while. Flashes of everyone is being shown...Prena looking happy, Anurag looking thoughful, Sam looking at her pyare AB, AB's brothers...after all of this is over Mukti looks up and is shocked, so is everyone else...It does that intense zoom thing on everyone's face for like a few minutes...finally we see Kul. The person who married Mukti removes the head thingy...Its Prem...Some more zooming in on faces. Prena looks angry and shocked at the same time. Mukti doesn't know whether to be happy, sad, or angry. Prem, Anurag, and Kul look smug. Flashback is shown of the planning of the stunt...Kul explains to everyone what happened. Prena storms off....Now you guys continue...What should happen next...
