man did not have to say these words to Flare.
He knew that Flare already understood this fact.
He could see that Flare was hungry for revenge but was also not impatient. He had readied himself for a long battle with himself.
That point was the most satisfying about Flare for the old man. Flare was not impatient. He was just hungry.
This hunger would make him want to learn everything like a blackhole until there was nothing left to learn.
This hunger would make him the strongest person that he never wanted to be.
Yes, Flare never wanted to be the most strongest person in the world. All he wanted was to be strong enough to face and fight his enemies and strong enough to protect his loved ones.
His desire to become strong is based on his past grievances but not because of some random reason like he just wants to rule the world.
