Armaan went too far with his pranking, and Mahira gave up and admitted defeat. He pretended to want intimacy with her, and sent a stranger in his place to romance her, while he filmed it.
<Never mind why she would want this abominable jerk's attention in the first place. He forced her to marry him, and she was demanding her "rightful" place as his wife and ghar ki izzat. The fact that she put on nightdress to await him was making me cringe so much.
What have they done to our Mahira??>

So , he thought it pretty funny to call her from the other side of the room, and watch her realize the position he had put her in. She jumped right out of bed, screamed bloody murder and threw her wedding ring at him and marched out.
And the prankster had the grace to look trite.
Just when I was feeling remotely happy that she had gotten herself out of that awful game she'd been playing with him <Mujra dance, again, really?> things became worse.
Now, Armaan is kidnapped by terrorists, and Mahira is going under cover to rescue him.

For a change , KB's side was mildly entertaining. KB gets annoyed that her new hubbie is sulking about lack of sex, and decides to stage an infidelity scene. She puts a fellow witch in disguise of her, and sends her off to sleep with Ehsaan. And then cries foul, and after a fine show of outrage and melodrama, she asks Ehsaan to sign over all of his properties to her as apology.

Truly, she couldn't have been more transparent... Fortunately, her MIL saw through her immediately and refused. Loved that. Finally , someone agrees with poor Dadi in a bottle.
So, KB's witchery is exposed and there is a battle for the property papers, which Saasuma is determined not to hand over. The good side fought valiantly, and some thingamajig-holy (beats me, the writers know more about this than an actual Muslim does) thing releases Dadi from her exotic prison.
Uh Oh KB you're in trouble...
