If she has an ounce of brain in her, she'll choose both. Here's what she should do....
First, tell Kabir everything.... her old habit of taking mahaan decisions without telling affected parties has backfired too many times, she should just take her hubby's help this time.
Once Kabir knows, he can use his contacts to put the fear of god into the corrupt doctor and get him to sign a paper admitting his culpability.
Then Jyoti can throw that paper in Pankaj's face (as well as the divorce agreement) and tell him---- Sorry to burst your bubble honey, but I'm going to get Roshni anyway. Are you going to give her to me, or do you wanna go to jail and then I get her?
Actually at that point it would be best if she got him to confess his crime and then get the cops to arrest him.
The one thing I don't want to see is Jyoti crying and pleading in front of Pankaj and then being her old mahaan doormat self and trying to choose between Kabir and Roshni. Get a brain, woman !😡
