Another place where we were getting wonderful results was Defence Against The Dark Arts. After Lupin left us, Dumbledore had an uncharacteristic bout of good common sense and decided to hire in a real live Auror. Who better to teach Defence than someone who has made Defence his life's work? Of course, it never occurred to him to Legilimens his new teacher, but this is Dumbledore we're talking about. If I were a Legilimens, I'd check everybody out all the time, just on general principles, after what we found out at the end of the year. But I'm getting ahead of myself.
