"Where's the DADA teacher?" Blaise wondered. They had never yet had a Defense Against the Dark Arts teacher who had lasted more than three terms. Hermione scanned the table carefully. Tiny little Professor Flitwick, the Charms teacher, was sitting on a large pile of cushions beside Professor Sprout, the Herbology teacher, whose hat was askew over her flyaway gray hair. She was talking to Professor Sinistra of the Astronomy department. On Professor Sinistra's other side was Professor Snape. On his other side was an empty seat for McGonagall.
