Vanessa and Casper explore the theme of Persistence in chapter twenty-six of Harry Potter and the Half-Blood Prince. This week we discuss Voldemort's fatal flaws, Harry's great strengths, and the imminent loss of Dumbledore will all its implications. Throughout the episode we consider the question: when do you know that you should persist on someone else's behalf?

Thanks to Katherine for this week's voicemail! Next week we’re reading chapter twenty-seven, The Lightning-Struck Tower, through the theme of Earnestness.
