Douglas casually transfigured the small stones beside the path into several stone chairs, then said to the students who had failed:
"Looking at your performance, I think you need to do some serious reflecting.
For the rest of this session, you need to find the corresponding passages in your textbooks for the questions you got wrong on your exam papers and memorize them. Any questions?"
The students hurriedly shook their heads and cautiously walked over to sit on the stone chairs...
Douglas snorted and said in displeasure:
"Did I say those chairs were for sitting? Lean over them and carefully work out why you failed this exam. Out of the entire third year, only you lot failed..."
The more Douglas spoke, the angrier he became. Even Neville, whom they constantly criticized and mocked for having the worst memory and liking to learn everything by rote, had earned an Exceeds Expectations on this exam. Yet the only failures in the entire third year had come from Hufflepuff. How could he not be angry...?
While Douglas was lecturing the students, Ernie Macmillan's mouth never stopped moving in the crowd beside them.
"I knew this would happen."
"Professor Holmes has never let us down."
"I have some inside information about this practical lesson..."
The class representative beside him, Justin Finch-Fletchley, had reminded him several times. Ernie readily agreed each time, only to start up again soon afterward, without caring at all whether anyone around him responded.
Finally, Hannah Abbott, unable to bear his pestering any longer, growled, "Shut up!"
Ernie Macmillan said to Justin with exaggerated flair:
"Oh, my dear class representative Finch-Fletchley, Hannah wants to take your position."
Justin also growled at him, "Shut up!"
After that growl, Justin immediately felt considerably better. His roommate's mouth... really did run far too much.
