Yep, depending on what elements you weigh the heaviest, Knights and Pages in particular get complicated. That’s really the only thing that throws me off in determining which is Passive and which is Active.
The reason I currently come down on Pages as Active is twofold. One, I simply think shaking up the current reading of Knights and Pages is important, because most people’s readings of Pages is really off, frankly?
But two, when considering it this way, I keep getting tripped up by other examples. Like, Muse is the Most Passive apparently–but Alt!Calliope has her greatest impact through her own direct action by blowing up a sun. Lord is the most active, yet Caliborn and Lord English have most of their direct impact on the plot through the ways they coerce, manipulate, and influence others. What stays consistent is who benefits, regardless of method. Calliope and Alt!Calliope’s actions are basically always to the benefit of others. Caliborn’s machinations always benefit himself.
It’s possible that’s a quirk exclusive to Master classes and there’s more to figure out about how Active/Passive works for the other classes, but for the time being I use it as a guide and consider the “For oneself” vs. “For others” habitual distinction the most important one to consider for Pages and Knights. Pages tend to benefit themselves, Knights tend to benefit others.
