This week, Vanessa and Matt explore the theme of Symbiosis in Chapter 15 of Harry Potter and the Half Blood Prince! They discuss Slughorn’s exclusive holiday party, the ripple effect of Hermione and Ron’s tiff, and Draco’s plan! Throughout the episode we consider the question: how can we create symbiotic relationships that aren't just transactional? Next week we're reading Chapter 16, A Very Frosty Christmas, through the theme of worthiness with Julia Argy.
