The writers are being cynical. They have made the Vamps too clever. Razia has seen the big picture:
"Soulmates will end up together whatever you do to stop them, Look at Asad and Zoya; then Aahil and Sanam. Their love always brought them back together. Although their stories ended tragically, their Love is legendary, and will reappear again and again, no matter what you do.
"So why not we do things differently this time? We unite the soulmates, the MFEOs Azaad and Mahira, and use them to strengthen out powers...!"

<Owhhh... how cynical...>
So KB has given up the helm of her game to Razia completely. Razia holds all the cards and schemes. But while the plot was being hatched, someone was listening...

A little villainous sleuthing later the eavesdropper's identity is revealed...
Naser sahab...
He refuses to eat the spiked food and drinks only water, and he leaves to make sense of the dangerous mischief he had just overheard. He heard everything: KB and Razia are in cahoots, they have Mahira's brother hidden; and they want to replace Amaad with Azaad as the groom.
His heart is in the right place. He figures that Kainat's disappearance maybe related to this scheme too. But alas, before he could counter scheme, he falls in a theatrically graceful faint (seriously , how awesome was his fall! He must plank a lot !! LOL>
Next step: drug Amaad into misbehaving with Mahira.
Amaad has his love potion and goes all amorous on Mahira and she fights him, witnessed by Azaad. ...
Elsewhere, Kainat and Lateef-Ghazala are held hostage by a hooded man who wants the Saira Bano dolls she took.
Precap: Dupatta and bride falls into Azaad's arms. IN front of everyone...
Oh Boy...
