RAJ'S FATER IS....

I THINK ITS JIGNESH(ARJUN'S BROTHER IN LAW)

REASON:ARJUN DON'T WANT ANY 1 KNO ABOUT RAJ SO I THINK RAJ IS JIGNESH'S ILLEGIMATE FROM AN EXTRA MARITAL AFFAIR....ARJUN AND DADI KNOS BOUT IT BUT DON'T WANT RASHI N D ENTIRE FAMILY TO GET HURT SO DEY R TRYIN TO HIDE RAJ'S FATER'S IDENTITY..........
