On the bright side, you don't have to know much about Jean from where I'm basing him, since he's very much at the bratty-loud-and-annoying stage.

Actually, the Abridged version isn't too far off. The main difference is he has a soft spot for pokemon and has tiny wings on his lower back thanks to being half-Flying Enlightened and if you ever want to be screamed at, simply mention them in his presence and he'll flip his shit.

Really, he'll get better... someday...
