we re RPing as much as we can.... so when you RP [ monty, the bloodthirsty pirate ] - you are a bloodthirsty pirate and the scourge of all lawfuls..
when you re on [ Tommy, the shiney Templar of the law ] - you re a lawful officer and the bane of all unlawfuls.
and you DO NOT MIX THEM.
so the weapons dealer is NOT your superior.... in fact your superior does not know what you do, unless he finds out about it in RP. - the weaponsdealer is a totally different char. - mixing them is what one might spit out as "metagaming" of the worse case.
