Leo- Leo no longer has a personal memory! He doesn't remember himself, Shawn, or anyone else. He also doesn't remember that he's an alchemist, or any of his training. Stuff will randomly transmute at his touch, so sorry to all of you who have their walls turned into dust, or something of the sort!
Shawn: Shawn was stuck in the blue zone, while flying no less. He is now convinced that he can manipulate water, despite the fact that he is flying, and can manipulate air with the slightest of thought. Half the time he tries to manipulate water, he unintentionally affects the air.
Poor Shawn's going to attempt to talk sense into Leo, but it's not going to work out too well.
Aden- Was thankfully off school grounds when the world exploded, but he is on campus now, ready to take advantage of this situation and be extremely amused.
