I still don't get how Graham could become a "good guy"... Hasn't he been a good guy right from the beginning? The only "hero" in this series who's actually a clear villain is Ali. The CB is a terrorist organization, despite the fact they have occassionally attacked other terrorists, but that doesn't make them heroes (a murderer who murders criminals is still nothing but a murderer. Even a police officer can't on purpose execute criminals - only on self-defense they can shoot them dead if there's no other choice). So, if we want to get more heroes in this series, it would require some of the old meisters at some point turn against the Throne meisters.
