Vanessa and Casper explore the theme of wonder in chapter sixteen of Harry Potter and the Prisoner of Azkaban. This week, they discuss flobberworms, how Divination class is like divinity school, and why Professor Trelawney doesn't believe in her own prediction. Throughout the episode they consider the question: Should we try to answer unanswerable questions?

Next week we're reading chapter seventeen, Cat, Rat and Dog, through the theme of innocence. Our voicemail this week is thanks to Laurie Benson. Don't forget to buy tickets for the east coast leg of live tour (which starts this weekend!): harrypottersacredtext.com/live-show
