He proved himself in the Martac Waste, so all he really needs is the proper impetus... Someone to piss him off, and he will be a proper Marine. As I said about the Kingdomite who irritated him, all it took was someone not doing what he was supposed to, and he pulled rank. REAL Rank. Let some people say what they will, no matter where in the chain of command, only a Marine can have Rank above the one simply called "Man."
