Great chapter. I wonder how much of the bragging between Olympe and McGonagall could Fleur and Harry actually do and how much is just plain overexaggeration.
For how Neville is in the Tournament, I theorize that Bartemius Crouch is still under the Imperious Curse and put Neville in; it might also explain why Crouch was in a good mood around Neville and even helped him out.
