Sigma appears to be kind to his customers at the Sky Casino, given the fact that he gave a customer another chance by saying that the game is invalid. He also appears to have a strong sense of ownership. He acts confident and composed even at times of crisis in front of his staff, giving the impression that he's the perfect casino manager and a capable leader. When left alone, Sigma starts freaking out and he admits he has no confidence in his skills as a casino manager.
