Well, I kinda feel guilty, because it's a little exclusive. Not All the characters will be involved in the Extreme and Violent thing, but the escape will involve anyone who basically chooses to escape. Plus, Extreme and Violent might not have been what NATC had in mind for the story, and keeping the event relevant would be tricky, unless someone was willing to take on that... responsibility.
So, the thing that happens is the headmaster is talking to one of the orphans, and things get a little scary. Out of fear, The Orphan attacks in self defense, and the headmaster is either injured, or dead, basically. So like, now they're on the "Shit List" and need to run, and some of the other orphans who were planning to run anyway just come along because they need out, and the Headmaster is "Out Of Commission" so better do it before he wakes up/someone finds the body.
Now... Since it's such an exclusive Idea, I was kind of hesitant to tell you all, but since you all asked. :v
