This is Nathan:
He is a good brother. A nice compliant boy, whose older brother has convinced him to hold a sword over his face. This is so that his brother can shoot plastic discs at the sword, or his face. Whichever.
This is Samuel:
He just happens to be the older brother and boss. He is the one who can bully his younger brother into being the target, the fetcher of things he needs, or the scapegoat. It all depends on the situation at hand.
I must add that no one was hurt, and that fun was had by all.
