i don't know if this has anything to do with being a Royal or not but this is what i think of Armaan:
He is the type of person who WANTS to be fair, LIKED by everyone, NICE, a LEADER, however, unfortunately when things don't go his way his ego gets hurt and his other side comes out... (Loud, Bully, Aggressive) ... and then after sometime he realizes what he has done... that's why he starts apologizing...
He just doesn't know how to control his anger/frustration... When people go against him he feels REJECTED... and he doesn't want that... So he becomes so DEFENSIVE... but when he is normal he is very entertaining..
He is a good person in heart i think...
Just to Clarify i am not anyone's fan... nor do i hate anyone in this show... i just watch this show as a neutral person...
