Vegeta woke up one morning and ran to find his dad, for today was the day he would learn to roar like his father. When he finally found him, Vegeta was mor than ssuprised. His brother was with his dad and when Vegeta walked up to him he asked, "Dad didn't you promise you would tech me how to roar even if brother came hme from his hunting trip early?" His father just pushed him aside and siad, "Go away Vegeta I have to teach your brother the ways of the king."
Heart broken Vegeta ran away from his father and never wanted to see him again, because this was the fourth promise he broke just to spend time with Vegeta's brother.
