How could be the son of the once Ruler of the Universe an idiot?
Avion was in no doubt, talented. It was just that, being alone his whole life makes him dense or even blind to some things.
He needed his training. However, it would show his real strength to Darea. The best that he can do was to meditate. Plan about everything ahead, become a pacifist to avoid danger. and rest whenever he wanted to.
In this way, Avion could blame it to his "mysteriousness" on why he does things.
When Avion said his "worries", Darea knew what he meant. In contrast to the former's expectation, the latter was actually accepting and tolerant.
"Don't worry, Sir Teller! I am just bored whenever time stops. Now that you are here, by just observing you, I will be fine."
"Oh? Even if my mediation takes days?"
"Even if it takes days!"
