Exactly, and look at Stanley's reaction. It was totally, utterly inconcievable to him that Parson wouldn't have understood the order. Parson was a Warlord - simply by virtue of his rank, he should have instinctively known exactly how to carry out the order and manage Gobwin Knob as he was meant to. Any other unit in Erfworld, given Parson's rank and orders, would have known what to do without being told. The knowledge would simply have been there in the unit's mind.
Parson's a special case when it comes to this instinctive understanding of Erfworld's Rules, perhaps because he's not a native. But if anything, I think Stanley's reaction to Parson not managing Gobwin Knob properly supports what I was suggesting before. Any Erfworld unit has an instinctive, intuitive understanding of the Rules that apply to anything in their sphere of influence. Units with Leadership just seem to have a clearer understanding, and through that, a better ability to bend those Rules.
