Khander Rao hasn't changed much in these 7 years except for being a trained warrior & strategist. But his stubbornness and adamancy remained the same. But but but...this time I feel Malhar Rao is equally wrong. He too never behaved with his son in a matured way. Its his duty to tackle him the way he need to. By this time, MR must have known KR's nature and he must have understood that he can't be tackled in a strict way, rather than giving compliments & encouragements might help him. You know when persons behave the same way as KR is doing right now (except for the drug addiction part)? Its when one struggled a lot to achieve the position they wished to attain for themselves and faced a lot of people's underestimation about them. And when they've achieved that, they try to be over-proud in front of others, but deep inside you'll see they are very less confident about themselves and thus they desire that others would praise them & their achievements. And this time, MR telling KR about his procedure of activities being not right was very wrong. He may have told that to KR in private after praising him for his achievements. But no, MR is equally stubborn & vengeful like his own son. No wonder KR's attitude has shaped up like this.
