One think I caught that I don't think the show had established before: when Nora's work with a particular "godchild" is done, her wand vanishes? But, how did she get to the point that she can apparently pick her charges? Unless it's a "Crisis, just go with it" situation, of course.
And, since I am of that generation, I have to give props to Belinda Carlisle! Great to hear that song show up.
