I think there’s more that this episode is trying to say than what I was actually able to comprehend, but in the midst of its confusion, I caught some cool ideas about the nature of what a book, or any other work of art, is.
In this episode, a book-type alien is the curator of the universe’s largest library. In a way, every work of art is a curation of the influences that go into making it. This could never be more true than it is of Shinichiro Watanabe adventure shows, which are always an amalgamation of styles and influences from all over the art spectrum. Each of his shows is a curated library of other works.
We also learn that the book-type alien cannot move, think, or act on its own, but actually possesses others to do those things for it. This makes a pretty fascinating sci-fi take on how art happens, especially when you think of how many writers claim that they don’t really create a story so much as allow it to manifest and live on its own. This is a literalization of that idea–the book is seriously writing itself.
