I think Nimmo is going to prove herself to be infertile. Meaning she can't have babies. That way no one will bother them about the babies. And Kunal can marry Natasha. Just a guess.
Aaahh, well at the current rate this awful track is going, I so wouldnt mind seeing that. Infact the quicker she proves this the quciker she'll be able to get out of that wretched house.
But if Kunal realises he love Nimmo really soon (which I doubt will ever happen) then I hope this doesnt happen!
I guess Nimmo will take a certificate that she is infertile, or maybe make herself infertile or something, only to know that she is already pregnant, and the story will take a twist...
