In the Rani track, Sona could immediately find out that Rani was acting to be drunk and then did all the drama....She even told Rohit that since she is an actor, she can easily figure out who is genuine and who is acting.... And Rani was an actor as well, Nishi booooooo is not even an actor.... Shouldn't she easily be able to find her true colours becoz of her little stammering and over acting???
