Neville was in total disgrace. Professor McGonagall was so furious with him she had banned him from all future Hogsmeade visits, given him a detention, and forbidden anyone to give him the password into the tower.

“Is it true that you shouted at Professor Umbridge?” “Yes,” said Harry. “You called her a liar?” “Yes.” “You told her He Who Must Not Be Named is back?” “Yes.” Professor McGonagall sat down behind her desk, frowning at Harry. Then she said, “Have a biscuit, Potter.”

“Only the difference between truth and lies, courage and cowardice,” said Professor McGonagall, who had turned very pale. “A difference, in short, which you and your sister seem unable to appreciate. But let me make one thing very clear. You are not going to pass off your many ineptitudes on the students of Hogwarts. I shall not permit it.”
