A most singular work, this is true.
It is not often, these days, to see a true piece of science fiction, one that is daring enough to ask a question, and to ask that question in a way that it does not make it too simple of a question.
Indeed, this is one of those rare pieces, something that can best be described as "art."
To the plot question: something had to happen, in order for this work to be complete and not a soap-opera. Light was as successful as what was needed to explore the question; anything more would have been too baroque. I find the entire Near arch to be... a good symmetry (I will not say perfect, as I do not believe in perfect symmetries in a complex dynamic, but this was as near perfect as a human storyteller can make it, in both the anime and manga).
