"Ah, yeah, that's cool," he said. Weapons were cool. Though he wasn't exactly opposed to just using his fists. There was something pretty satisfying about just punching people in the face. Or other places.
Honestly, Atticus was sort of pleased that there was someone else at Hogwarts who seemed to like violence. "We could probably get extra muggle weapons here at Hogwarts." Or at least get to practice fighting more. There was something about it that just settled him. Blood and violence were the best things in the world.
