Hehe. It seems to me, my dear sister, that you've got three universes wrapped up in this story: (1) Harry Potter, (2) Star Wars, and (3) Star Trek. That line that Seamus says reminds me very much of something that Scotty would say to Kirk. :O}

And ooh ... jumping when they're in the middle of an asteroid field?! I don't think that in anyone's space universe that they would recommend doing that. It would rip the ship to shreds!! I believe calculations are always made so that they travel around space bodies ... otherwise their gravity would affect things (asteroids do have gravity you know).

:O))
