I consider it to be a pretty good response to the spirit of the question, which was asking about compositions that got shelved. He told me the inspiration for and story behind one that did, and how it's now not only in Volume 4, but the theme of Volume 4. Because of that, it's a snippet of insight into what the next volume was going to be like for Ruby and those around her. I am not at all unsatisfied, especially since he didn't have to answer me at all. ^.^
