In addition to teaching the group Dark magics and how to duel, Lucius took it upon himself to teach them how to guard their thoughts and memories with Occulmency and how to think like a Slytherin. Cunning, stealth, and how to twist words so one would get their way were just a few of the things the Gryffindors learned. Despite himself, the blond found himself growing (dare he admit it?) fond of the small group.
