...The King had a rough time: he had two sons worthy of throne, but there was the third one who gave him problems more than everything else put together. Everyday the Pride went to the borders to pull the stupid King's son out of another trouble. It would be okay if the son was a victim... In opposite, the young teen with barely grown mane was the only who caused problems for all the Pride. With other animals and neighbour-prides, as well as loners.
Once, the King has finally lost his patience, he stopped the lions not far from the border, lectured the middle son right in front of the whole Pride and ordered him to get out of the Pridelands.
"You are a shame of the family!" the King Rokho yelled barely holding from tearing the poor boy to pieces. "I'm sick of your vagaries, Sky! From now and forever, the borders of the Pridelands are closed for you!"
"Wha...t?" the boy was startled.
The Queen Aegis kept silence in disdain and wasn't going to stand up for the child. All of them were sick and tired of him. No one said a word, no one objected to the will of the King.

This was a reason why Sky has come to hate of his family and still does it. In most cases, it was his fault, but he was young and believed that father had to accept it. However, the reputation was the most significant thing for Rokho rather than parenting of his son.
