He did whatever Karan tell him to do in the task. Karan easily got the 2 people he wanted along with him in the VIP room by manipulating Umar. Umar doesn't have a mind of his own and is only following Karan's orders like a chela. He should've chosen Afsana ahead of Tejaswi or Nishant because he has better equation with her. But Karan made him choose Tejaswi and Nishant because they were his priorities. Umar is a fool.
