Five years, 100 episodes, every single conceivable permutation of the f-word, and a 45-minute summary of a pretty throwaway chapter. Welcome back, witches! Sorry we wrote that. Anyway, this week, some classic Rowling quirks rear their fat pig heads, including ugly villains, reactionary teens, brutal foreshadowing of fractured families, and cool hidden Hogwarts tricks. Harry also does a torture. Plus: We … sing? A lot?

This time: The Sacking of Severus Snape

Next time: The Battle of Hogwarts
