The character of Shahrukh Khan in this movie changes, due to his own therapy and its effect on his patient, Alia..! The only condition is that the acquaintance has to be friendlier and there has to be a connection between two personalities, to make this magic work. This can happen between two close friends, or between two people who are able to connect to each other, at an intellectual level, very well. Just as the induced current in a conductor changes the original character of the coil..!
