Me, Myself, and I

Meet Ailerie. Also meet her two other personalities: Carmine and Kaitlynn.
Ailerie has MPD or as others would know it as: Multiple Personalities Disorder.
But she is different than your typical mental person, when others switch unknowingly to their other personalities, Ailerie can access her other personalities on command.
Kaitlynn is amazingly smart and hates running or any sports in particular.
Carmine is the athlete. She is an avid tomboy and loves anything having to do with combat.
Ailerie, well, she is just about everything else. She's alright with sports but doesn't get too obsessed. She can be smart but not a straight A student. She is pretty average in popularity and catches a little drama. But when it comes to boys, might as well go find Area 51.
Some people might envy her. Some might feel sorry for her. Some might think she is a lunatic for hearing voices in her head. But to Ailerie, there is nothing like having your two best friends always in your head.
