alrighty so HEADCANON TIME ABOUT the Graybles episode, the flappybeard is what’s left of Future Ice King… but NOT Simon Petrikov. At some point after current events, they succeed in tearing out the Ice King from Simon, excising the degeneration and power of the Crown from him, freeing him without killing him and letting him be free while it takes on a life of its own that persists even into the FUtURE
i like this!! i was sorta leaning into something like that, or that betty just plain made the crown into a separate entity from simon! either way it’s cool to see how the endgame came out!!
