People were actually scared that Karan comes back and faces Jennifer once again, will both of them act professionally.
However both of them are acting too professionally. There is very little communication between them once the camera is switched off. They joke, play prank with each other but certainly within limits.
So will they remain aloof to each other for long, or Armaan and Riddhima will once again be their usual self.
