[The basic points to remember in this world seem to be that Hearts Are Very Important and Everybody Is Completely Insane. Good to know. He takes a few seconds to process all that, and then a few more for good measure. This is making exactly zero sense without a good understanding of how their world works, but he can get context later.]

You all managed to stop him, but nobody's actually killed him yet, right? Because if you haven't, and he still has twelve hims - which still does not seem physically possible [No, he really can't let go of that one, because seriously what the fuck] - then he'll probably still be looking for a thirteenth, right? Which means if he is the one behind all of this, that makes everyone who's stuck here a potential thirteenth him. What it doesn't explain is why he'd drag in people who've already beaten him before, unless he plans on getting revenge on top of everything.

Does any of that even sound plausible. [Because he's kind of lost sight of logic at this point.]
