"First of all, it was in my contract. I knew I would be directing an episode"

In this quote, Anthony Michael Hall is discussing that he was contractually obligated to direct an episode. This suggests that it was a part of his agreement or legal document that he would take on the function of director for one episode. He knew this from the beginning and was aware that it was a responsibility that he had to meet. This shows that being a director was not simply a random choice or chance for Hall, but rather a prepared and agreed upon element of his participation in the project. It also highlights the professionalism and dedication that Hall has towards his work.
