When did this attack on the Queen happen and Harry's defense? The whole event came out of nowhere and had an equally surprising resolution. How did Harry know to be there at that time and place? What prior contact was there with the Queen? Why was it never followed up?
A lot of chapters and scenes from this story seem to be missing. For examples Harry saying he isn't returning to Hogwarts in one chapter, then the next chapter opens with his dramatic return by appearing in the Great Hall. There were several other jarring scenes.
