I am 100% sure that karan will come back cauz if they didnt have to bring them back thenthey would have shown hid body
Then after sometime they will reveal that ranchod id karan itself and he kept this as secret couz of massi and our abharan will be back
It will take time but i think this will happen
I think karan will lie couz only karan has signed the papers and not ranchod
so if he would have not lied then they would have proved that ranchod is dead and would have grab SB as they'v karansign
