see if he is deliberately hurting ekam then his actions would be logical, wrong but logical but if he doesn't hate ekam then his actions are illogical.sartaj is completely illogical as a character - all the way from how he enters the show, nehmat cares for him, how he declares she is his fiancée and so on. I think when sartaj will exit the show they will tell us that he hated ekam from bachpan because everyone loves him and that is why he played his game with nehmat - to hurt ekam. Harleen scene was nice.
