Finale? Is the story over? It is for David and Dead Palette after they stumble across something in the most recent update to 1999 - something so bizarre that it changes their opinion about the entire story thus far.
Story itself begins at 41:04; the passage that changes everything starts at 1:36:52, although we encourage you to listen to the whole thing for context.
