He guys I am just saying this perdiction because of upcoming leap
I think Prem will die either on tuesday or later in show and Prerna will go into someking of shock and then their will be 20 years leap.
Then someone will find prem's look alike. But he will be Prem's son with Devki somehow. Then Prerna will be alright.
OK!! perdiction is little like Prem's situatuion But in this way Manoj can not leave the show and he will be playing 10 years younger character..
