I'll challenge Sel Han as soon as I'm up and around again. That ought to square everything, and if I win, why, the first part of my mission will have been accomplished. Unfortunately, replied the scientist, that will be impossible. According to our Martian code, it would be unethical for you, under any circumstances, to provoke another duel with Sel Han. He, on the other hand, may insult or humiliate you all he likes, so long as he uses no physical violence, and does not have to stand challenge from you, for he is technically the victor.
