Because apparently the message isn't getting through to the Gryffindors some people despite how often I've been saying that, warn any susceptible people in your houses to be really, really careful around Umbridge.
Pick your battles with her, meaning don't pick any of them. And do not by any means take on either her or any students who seem to be close to her. I know this probably isn't the most noble advice for me as Head Girl to give, but people (both students and teachers) who challenge her seem to lose what little authority they have left. So if you're unlucky enough to earn her notice, go along on the surface and then try to help anyone affected tacitly afterwards. If you're caught up, plead ignorance.
This isn't about integrity. This is about covering our arses and trying to maintain what little power we have left to help the other students. She's taken away our DADA tutorials, but at least we prefects still have the ability to award detentions without consulting her first.

Roger knows. Everyone knows. Not that I needed to add that part after the "Roger knows," but yeah.
What do we do now?
