Pro, about you asking to reserve the volcano long ago, I didn't knew, or if I knew, I really forgot it COMPLETELY (ehy, I am really old, what do you think?), otherwise I wouldn't have placed the UFO inside, and I would have felt offendend by your remark (which, by the way, was the thing about ridding off the ufo, not the reserving of the volcano).
What you have written clearly shows the love you have for most characters and the whole Universe, so I hope you don't stay away FROM THE STORY.
About the thing of writing character like himself (I thing that I ever state), I want to explain why: first because I wouldn't be able to do it in a different manner and second because for me is the play the most important thing, is the dream of being someone with powers. I am a child at heart, and I am happy with it.
