I still feel harsh is samar

As we all know that samar was tech genius so he may have somehow tricked skype. And he always wanted to become an actor in which jj may have talked to his father and convinced him giving samar a chance to prove his acting skills . He may have created the char of harsh and wanted test his buddies like provoking kd and trying to make rv more selfish and try to make them fight and test how strong is there friendship and how the buddies react when they are put under bad influence .and hence improving character of buddies and if harsh is not samar then this whole track is gonna take atleast half years which would include makon grey char of harsh to white and making him friend with everyone including kd and piddi and making him get over kiya what is your thoughts on this one .
