Intrigue! Betrayal! Torture! Finals! This week's chapters have everything. Harry overperforms; we meet the series' first competent bureaucrats; Hagrid refuses to go quietly; Sirius gets dream-kidnapped; Kreacher gets his revenge; Draco is the Salacious Crumb of Slytherin; and Hermione thinks fast. Plus: Madame Ponfrey has accurately identified herself as the only one standing between the entire student body and certain death.
