Since disbanding Team Skull, Guzma is trying to establish direction in his life. He can still be a volatile jerk, though he may try harder to rein himself in and feel bad about if he fails. Guzma has a job, good for him! He should be proud of himself for managing to get one and hold it down, but at the same time it is EXCRUCIATING because he's still Guzma after all! But he takes his job seriously and it ain't glamorous but it's an honest paycheck for the first time in his life.
