This week, Vanessa and Casper explore the theme of Discovery in Chapter 18 of Harry Potter and the Half Blood Prince! They discuss Slughorn’s poisoned mead, Harry’s life saving bezoar, and Romilda Vane’s love potion! Throughout the episode we consider the question: are we always on some journey of discovery? Next week we're reading Chapter 19, Elf Tails, through the theme of Rebellion with Matt Potts.
