Do you think the yellow king-insanity thing is all related? Ladeoux, the guy who committed suicide, and Rust all being insane, I'm thinking it has to be something they have all seen or heard. I also think those devil catchers are going to have some sort of masonic geographic tie in. Like once they figure out which kids were actually taken by the yellow king it will be geographically in the shape of one of those demon catchers.
Flame at me bro!
