This week, Matt and Vanessa explore the theme of Invisibility in Chapter Thirty-Three of Harry Potter and the Goblet of Fire! They discuss the newly visible Dark Marks, Voldemort's still unnamed "faithful servant" at Hogwarts, and the masked Death Eaters. Throughout the episode we consider the question: what do we make visible with our care and attention? Next time we're reading Chapter Thirty-Four, Priori Incantatem, through the theme of Conspiracy.
