Aeryon did not know all of the thing that is happening right now. He did not know that Belarion is worried about him, worried about how to help him
However, Aeryon does understand Belarion and even if Belarion did not say anything, Aeryon did think of him
Because while James does not know much about Belarion, the moment he became Aeryon and inherited his memory, he also felt a kind of familiarity with Belarion.
And Aeryon knew his sworn brother well. And that is actually one of the reasons why he wanted to meet Belarion tonight.
He needs to act a bit tonight. There is something he wanted to tell Belarion.
Aeryon did not know that Belarion is suspicious of his newfound strength.
But it is not something that Aeryon failed to anticipate.
After all, the moment he fought those two tribes without even being injured, he knew someone would suspect something.
