Dumbledore's departure made Hogwarts a lot less attractive, though, and they decided to use the time before they were kicked out to make Umbridge's life as difficult as possible. They did everything they could think of---and couldn't they think, just! I had to admit that I was in awe of some of the things they came up with to torment our usurping Headmistress. Keeping those two on my side shall be one of my priorities.
