Back in the Great Library, Mina is putting books away when Jakin comes up behind her in some excitement. "Mina, do you think this is a magic library?" "Of course it's a magic library." She manages to restrain herself from adding anything more sarcastic to her reply. "No, I mean, I was reading this really good book, and I really wanted the next one, and when I went to put it away the next one was there!" "Yes," Mina says, a bit less patiently, "that's what happens when shelves are properly sorted." "This wasn't from the sorted shelves! What should I do?" Mina stops and considers her brother. "Maybe say 'thank you' to the Library?" she suggests, and it is not really even a joke.
