Somewhat improved. Grammar is still off, but the Semblance works better. Spontaneous aura combustion or something like that. Mild pyromania with a strong preference for detonation over deflagration is about on par with sociopathy, and while I have a preference for sociopaths as "interesting" characters, others may feel differently. In terms of roleplaying the character, I'd suggest rolling a D20 or something any time he uses his more... "unstable" equipment.
