Sam

Who he is
A information keeper of Butch's gang, he's also the guy who helps out Aaron in a whole load of messes.

Personality
He's doesn't have much in term of personality besides the fact that he sometimes is a bit lazy but does get concerned about himself, other people and their safety among his own. He doesn't really help Aaron out of Apple Ocean City all that much but did try to warn him (which failed from the Events of the Big Magic Show).

History
There is no history of him recorded within the story besides the fact he's known Aaron for a long time among his helpfulness.
