This time nidhi will be the surrogate mother...after returning from jail nidhi will have change of heart and she will help ishra trap shagun and then will offer herself to become surrogate mother so that ishita can raise a kid from its birth and get to feel motherhood through raising a new born since till date she only got to raise grown up kids...and ishra will happily accept it since nidhi also have quite similar history as shagun of torturing raman's kid for years and also spending nights with ashok...only point goes against nidhi is she is not CVs fav but rest she has all qualities similar to shagun
If ishita again becomes pregnant then mrs bhalla will ask all to visit some temple and shagun will plan to fit a bomb to kill ishita and her unborn child...if by chance ishita delivers a child successfully then shagun will take the role of nidhi and will elope with the child and after 7 years leap ishra will find about their 4th kid who is again manipulated by shagun to take revenge from ishita.
or with new baby's birth pihu will feel insecure and shagun will take advantage of this and will again manipulate pihu that ishita only loves her new baby and she doesn't love her as she ididn't gave birth to her and then the revenge saga continues
