Yesterday,Kabir's ego gets affected when ARM hands him a 100 bucks bill as a tip without delivering any service. While ARM's ego gets affected when Kabir, a mere server boy, offers to pay for his phonecall.
Today, Kabir's ego gets affected again when that doorman at a 5 star restaurant denies him entry because it wouldn't "fit his bill" whereas ARM's ego gets affected when the girl for whom he took to the fight challenge and to whom he intended to spend the rest of his life with, rejects him straight out for being from some "god forsaken land" of slaves.
Both men, even though in totally different circumstances, faced "Rejection" which irked their ego to a larger extent.
Ego is what urges them both to strive for something bigger and better in life. Ego is what will make Kabir emerge from being nothing to being someone with name, fame and wealth. Ego is what will make ARM emerge from just an apparent heir to being THE Merchant man he always hoped to be.
BUT, Ego is also something that will create the lifelong tiff between the two men. Ego will be something that would stand in between them till the very end.
