I think you should shape-shift yourself into something more attention grabbing like a celebrity and then have Sam deny it whenever somebody approaches her, just to mess with them. ;) Also, you may want to consider the fact that mostly everyone's characters are inside the school trying to at least get a sense of direction and rooms/dorms. I believe there's at least one more guy that needs to enter his character in as well.

Oh I'm a lurker, btw...Please don't mind me, I'm watching as a part of the audience, for now...*sinks back into shadows* (highly tempted to jump in and interact with your character though).
