what i think might have also happened is also that 20 yrs ago maybe when nadani gave birth to her child she might had a disease it could be because of ekta's weird mind. i think that nandani would like to see karan and his family settle and karan should completly forget about her.
i know i just said sumtin that will never happen but it could happen think about it remember ekta said one of these are going to die(sahil,tanya,nadani,ganga) which i hate see it happen. i would rather see tanya die.ðŸ˜ðŸ˜
