I think it has more to do with the extent that you're harping on about it. This is made worse by the fact that you were wrong about half you augment (The part about how the music festival is supposedly new information).
I think most of the people here even agree that "The Pixie" could have been established sooner. I agree to an extend, but I also think it would be a distraction if not melded with a relevant topic (Like how demon Idols and Evil Phases where established together)
Personally, I really like how the author establishes things, but keeps his options open (Originally, I thought that everyone in the misfits class were just going to be irrelevant extras, but they kept getting fleshed out as time went on. Now is simply Soi's turn)
