Sane, havent we already established that no matter what either of us says, the other will always disagree? :P Go back to your loli love!

Anon, Oracion Seis may have been locked up, but that doesn't mean they didnt get stronger. We saw Cobra working out in his cell. He already had a near mastery of his magic and in jail he kept his body in perfect condition. Training is not just about utilizing your magic in stronger ways, its also about being in peak physical condition, which we know at least Cobra was.
