Going Too Far (Harry Potter)

Two weeks into Umbridge's stay at Hogwarts. The teachers are reaching the end of their sanity, the houses are going to break into a full-out war at any moment, and Umbridge has a smile that screams evil. McGonagall and Snape come up with a simple idea to chase her out of the school. Things get out of hand rather quickly when the plan comes into full motion three days later. (OOC)
