[@Roosan] If you're driven enough, your character can 'overthrow' Eve in IC. Eve is part of the first BHHS and she's kinda a dominant bitch, so I don't really see her any less than Head. Sorry. Hell, you can even segregate the school even more in IC by trying to make your own division of Performers :P

There's always a possibilities.
Just because people are "Head" doesn't mean they'll stay head. Things can happen. Things can always happen.
