As frightening as it had been for the school’s population at the time, Umbridge’s breakdown and subsequent removal from the castle had breathed new life into the school's stone walls. Gone was the atmosphere of oppression and fear that she had ushered in, and in its place an optimistic lightness seemed to permeate the castle’s very foundations. Harry could have sworn he’d caught McGonagall whistling happily to herself while she instructed representatives of the ministry in removing Umbridge’s belongings from her quarters. In fact, the only person who seemed even slightly unhappy with her absence was Filch (who looked downright disappointed that his opportunity to cause the school’s students even more misery had been summarily dashed), and strangely Peeves, who had spent a week dressed all in black standing morosely in front of her classroom.
