I was most upset about the sergeant, myself. (Was he Janet or Mildred?) There were a lot of strange things about him. He was very old, and seemed to have been a sergeant to everyone in the army. He always wore red. He loved war. At one point they sang a song with a line like "And the devil will be my sergeant".

And it turns out he was...a woman. Which doesn't explain any of the things that made him interesting. Maybe the foreshadowing of him being some kind of Small God of War was too obvious, and only there as a red herring. But that was still a pretty lame secret.
