Xander was a few rooms over from the potions classroom, having come to the school to work on his own thing. He excelled in his potion work, and was pretty snazzy when it came to his projection. Not that there was much to it. When it came to his telekinesis he was alright. That bugged him. Not only did he see his mother's abilities with it many times, but he was also stuck listening to the stories of what she could do. That's the kind of power he wanted.
When he heard the explosion he was a good three feet up in the air. Using all of his concentration to lift himself by his shoes. "Shit!" There went his concentration, and there he was flat on his ass. He wanted nothing more then to just ignore it and get back to his work. Knowing he would probably get canned for doing so was all the made him drag himself to the potions room.
"Hello?" He poked his head into the smokey room and tried to find who exactly was causing such a commotion.
