Aang likes Leon as a person but worries about his leadership if only because Aang's used to self-reflection being considered a good leadership trait where he's from, but Leon is constantly on the go. He worries about his ability to stay centered. He's waiting and seeing before making any judgments though, waiting to see what kind of leader he demonstrates that he is.

Brainy voted for Nathan. He still doesn't like Leon after Leon took his omnicom ages ago, and is only following him because the majority willed it. He generally dislikes any leader that won't pander to his behavioral quirks, and also thinks Leon distrusts him, which puts a major chip on his shoulder. It actually, crazy as it is, hurts his feelings. (I don't know if Leon trusts him or not, Brainy just thinks he doesn't).

Jaime thinks Leon is like...kinda on the shootier side, but honestly? He sort of reminds him of his dad. Jaime knows decent people can be the types to shoot every bad thing that moves. He thinks he is very decent, and wonders if Leon sees the same decent person Jaime sees, but he doesn't want to pry and ask what Leon thinks of himself. He trusts him as leader and thinks that even if he makes mistakes, he'll learn from them.
