What's at the End of the Universe?

A lot of people miss the fact that we actually do learn a little bit about the character in the third book about Chung Machine's past. I think it was very effective and I wouldn't mind seeing kids there. But again, knowing that Yo and Jie's not coming back, I can put that out of my mind. It is really satisfying when Changxin meets up with Vojigio later on.
