I kind of wish Grim Tuesday had been involved more, but the story was good nonetheless. Plus, the portion of the Will in this one is kind of amusing.
I love the slow growth Arthur is going through. He still doesn't want to have anything to do with the House (at least until he's older), but he doesn't want to leave them in turmoil either. And yeah, his reasons for helping are also a bit selfish since the House is starting to affect his own family, but in the end, he becomes the hero for more than just that.
