Eric was wondering about the best way for him to train his new powers, since he didn't know how much control he had and he didn't want to harm anyone by accident. The fact that fire extinguisher girl was running around the entire room also made it impossible to simply throw small fireballs in the direction of the metal walls, because he might hit her. Eventually he got an idea, he would try and see if he could combust again like he did back at school, only entirely and on purpose this time. It was a lot harder than he though it would be. But after five minutes of focus so intense he didn't even notice the small whirlwind, he managed to cover his his arm in flames. When he got that far for some reason it became a lot easier and before he knew it his entire body was on fire.
