[I][b]Personality[/b][/i]
Studious, somewhat timid with those he doesn't know but open amongst friends. He's slow to speak, often mistaken as being slow of wit because he doesn't speak much at all. But when he does, it's very well thought out and reasoned. Does what he told, but often not in the expected way.
