Vanessa and Casper explore the theme of "necessity" in chapter thirty-three of "Harry Potter and the Goblet of Fire." This week we get into Voldemort's psychology, take pity on Wormtail, and discuss the human instinct towards survival. Our question this week is: how do we decide what's heroic? Next week we're reading chapter thirty-four, Priori Incantatem, through the theme of Grief. Thanks this week to Rachel Diebner for our voicemail.
