you and @revolutionarydeulist say that Knight's and Page's serve or are served their aspects but if Serve also means to give then don't Rogue's do that? taking their aspect to give to others

It’s part of the scale, too. The Creation and Destruction pairs seem sort of of mutually exclusive. The Serve and Steal pairs have some overlap, in which to Serve something you must take it from somewhere, and once you take something you can offer it, but there’s still a distinction. And then you have the Know and Change pairs, which have a lot of overlap, given Knowledge of something and how to Manipulate it kind of go hand in hand.
