Yesterday I made a post that it's not a ploy but today after knowing that Imlie was never pregnant, I'm hoping against hope that may be this is all a trap eventually
For starters: makers left their consummation ambiguous, did they didn't they?
What if...
Jyoti tampered the food so that Imlie will get sick. BD will hint towards pregnancy. Jyoti plants a faulty test so that it shows positive. Later she will orchestrate Imlie's fall so she lands in hospital and then bribe the doctor to give false reports that Imlie is infertile.
Now BM will brainwash N to banish Imlie and plant the idea of getting Aru remarried. This way Imlie is out of the picture and Hyoti can easily eliminate BM and BD to get in good books of N.
Now now, all this is based on Jyoti's belief that Arylie did indeed consummate but what if they didn't(and only they know this) and on getting positive test, their mind started working and they are just playing along to expose the evil trio.
I know the makers don't have this much brains to think all this and they are most definitely going the tried and tested formula of separation and sacrifice but a girl can dream right!
