Vanessa and Casper explore the theme of duty in chapter eleven of Harry Potter and the Prisoner of Azkaban. This week, they discuss Hermione's selflessness, Hagrid's traumatic experience in Azkaban, and McGonagall's harsh take-down of Trelawney at christmas dinner. Throughout the episode they consider the question: How do we differentiate between obedience and duty?
