As you may remember, this slave did not clean Lady Pascal's leather boots properly as she returned from a business meeting. He did his best but it started to rain and so he had no chance to do a good job.
Mistress Akella decides that her slave still needs more practice in taking corporal punishment. She orders him to lay down on the punishment bench and chains him there.
What a stupid slave who tried to breakout from Lady Pascal's stable. Or was he so much hopelessly? But he should know that there is no chance to escape and so he was caught and catched.
