But do you think even if KArman happen Suman ki pareshani and the tortures will end.. no .. instead all her troubles start once again with the double impact.. this time she might be called a dayan who scatched someone else's love for her own interest..
are I know and already mentioned somewhere in in my other replies tooo....that If Suman marries Kartik then har jeena aur muhaal ho jayega...as then VB will hav more pints and fact to rant against her ...like she has first took one saon and now her nazar is on another one....or she eyed on Kartik for a long time and now she has snatched her from Nandini as u said....
so in any case Suman ki pareshaani tab tak kam ya khatam hoti nahi dikhti untill karan comes back...only then Kaddu might except her as she will get her Lost son back...(m saying might coz she is a kaddu no brain to think...so may be then she will get another point to hate Sumi...)
