Kishwer's deception circle,victim-prince

During the kish and priya chat..kish stated that prince would not have left the task if it were a girl and Prince on sole dumbness agreed after that even went onto say he doesnt consider girls competition and called her victory his .you just negated every bit of hard work accomplished in that task. Accha hua rochelle baad mein aayi ..nhi toh jo voh band baajati .
Why doesnot he see through her..??
