When people are a victim of a practical joke they often start blaming everyone in the world, so it's understandable here...you don't want to believe that we were victims of a sick practical joke when we were led to believe that AA really is this saber-friendly, value seeking ninja. While your searching for a alternate answer is surprisingly slow (almost Stoeten'esk) it is understandable. Think of AA a lot like Inspector Gadget, he lucked his way through his job, for the first while, however AA doesn't have dog watching over him and a genius niece bailing him out of his trouble with her computer knowledge...AA has a lamb and a mother who's about to cook it for him.
In other words, the guy just isn't a good GM and he's surrounded by people that know less than he does.
