I'd like to think that Knights/Pages start out acting like the opposite of their active/passive role. As they grow up, learn, and get comfy, they start acting as the role they were supposed to. This "starting as the opposite and ending how you should" has caused a lot of confusion in the fandom

Yeah, but rather than acting their opposite Active/Passive role, it’s more that Pages are Served while Knights Serve, so it leaves Knights seeming to take upon a more Active role while Pages are relegated to Passivity. However with the more ‘Selfish vs Selfless’ view on Active/Passive Classes, the Page/Knight alignment becomes more clear.
