Kris knew that at the time that he was born, he is far different from the other wolf cubs. His growth is a lot fast than the others and his senses grew stronger as his mind starts to develop.
His thinking is also different from the others. It is much more advanced than anything else. He could make any decision in a split second and could kill any animal in one bite.
That's how powerful he is.
It could also be the reason why he doesn't have any friends to talk to. Maybe it's because of the aura he elicits.
They might be scared of the Alpha in him. But he doesn't care. He doesn't need them anyway.
As time passes by, his father sees him as a late-bloomer and would ask his pack mates and their children to befriend his son.
But in Kris's mind, they are just doing that because he is the Emperor's son and nothing more. The only person who made him feel like a normal cub is the Emperor's former right-hand's son, the Beta.
