When Sibilla and JJ are called to see to an errant slave, they know it's bad. This is a slave that has forgotten that he is a slave and has to be slapped back into submission. They wait for him and take him into their custody. They hold him and slap him until his face is bruised. As they slap him, they tell him he is a lousy slave and that he will be punished until he is a better one. They slap him back into his correct station in life, that of a slave.
