Why does Vikas Gupta pick a fight with Arshi Khan every weekend?

Everytime Vikas Gupta is disappointed in himself he picks a fight with Arshi Khan. She has become a living punching bag for him. Vikas is never seen fighting with anybody else and it has started to seem as if he is scared of fights because none of the contestants will swallow their words during a quarrel. Once again he fought with Arshi right after the question-answer session. Being from the same industry the mastermind calculated his place in the game with the help of the kind of questions that were thrown at him and they didn't seem to hold any kind of importance.
