Will probably talk way way more about this when we get to OOTP in the re-read, but I really don't understand why people have such a problem with Harry being angry and moody in this book. If it was me and I'd experienced what he had, I'd have gone completely off my nut. I mean, shit. It's bad enough being a teenager, but add Malfoy and Snape and Voldemort and Umbridge and whatever else on top? Come on. Kid never had a chance.
