The Peach never uses his relationship to his brother to his advantage.  How could he?  He grew up with the man as a boy.  It would be embarrassing.  He remembers all their squabbles and projects.  Using his brother’s position would be denying his own worth.  He’s got his pride.  He’s not some beer-drinking presidential brother.

He usually blows off anything other people say about his brother.  Look at him hop past it here.
