my first impression of the halfway point thing in chapter 4 was 8 whole ass chapters since the whole thing seems to be moving into an extended melodrama territory, knowing stories with calamitous events I would guess that the roaring is going to happen and the remaining couple chapters are finding a way to recover from that. don't get me wrong I adore the ending where Kris has to seal the castle Town fountain for some reason that one would make me cry but I imagine the roaring unleashed plot the most feasible way to do a straight shot of several chapters without doing prequel/side story chapters
My main beef with this unleashed idea is that it's too long of a plot to come to someone's dream but it's also tony I'm rambling about he could probably write entire musical plays about butter dragon inflation porn and porky minch saying nigger in his sleep
