In Chapter Twenty-Seven of Harry Potter and the Order of the Phoenix Fudge lists the people that Dumbledore would have to overcome to escape:
“So,” sneered Fudge, recovering himself, “you intend to take on Dawlish, Shacklebolt, Dolores, and myself single-handed, do you, Dumbledore?”
In Chapter Twenty-Eight the immediate aftermath of this event is described, but now there is an additional person that Dumbledore had to overcome:
The notices had gone up all over the school overnight, but they did not explain how every single person within the castle seemed to know that Dumbledore had overcome two Aurors, the High Inquisitor, the Minister of Magic, and his Junior Assistant to escape.
The Junior Assistant is, of course, Percy Weasley. He was not mentioned by Fudge because he had left the room already:
Percy dashed from the room, slamming the door behind him, and Fudge turned back to Dumbledore.
Is the statement in Chapter Twenty-Eight therefore an authorial mistake? Or is it perhaps deliberately inaccurate in order to make the point that even though everyone knew, they actually didn’t really know? Or is there some other resolution for this discrepancy?
