They probably were just recording from the Noah's perspective, but since they've been helping the Order, couldn't they have easily helped the Noah? If so, then how? I also think that Bookmen age; just very slowly. There's been quite a few comments on how it would be unfortunate for Bookman (Panda) to lose Lavi at the age he is, which, by my understanding, implies that he's aging(?). Also, when we saw the flashback of Lavi soon after he joined bookman, he was a little kid. Obviously, he's grown since then.... I'm really wondering what is allowing them to age so slowly, if at all, and what significance it has to the story.
