And it makes perfect sense for an alcoholic, to just BAM, poof dead.
But I'm hoping we see an even more aged, embittered, and manipulative Schlatt looking to cause even more economic chaos than ever before ...and Mexican Dream I guess? but with Dream currently in prison Mexican Dream could pose a threat, especially since we don't know what role he actually plays outside of a meme.
To be completely honestly, I've not done much in the theorizing department as much as just appreciating the story. But I am excited to see what happens next!
