Ender's Game (Ender Wiggins Saga)

preserving and protecting the boy. Do you?”
      "Damn Dap and damn you too, sir, I know what I'm doing.”
      "Do you?”
      "Better than anyone else.”
      "Oh, that is obvious, since nobody else has the faintest idea what you're doing. You have known for eight days that there is a conspiracy among some of the more vicious of these 'children' to cause the beating of Ender Wiggin, if they can. And that some members of this conspiracy, notably the boy named Bonito de Madrid, commonly called Bonzo, are quite likely to exhibit no self-restraint when this punishment takes place, so that Ender Wiggin, an inestimably important international resource, will be placed in serious danger of having his brains pasted on the walls of your simple orbiting schoolhouse. And you, fully warned of this danger, propose to do exactly--”
      "Nothing.”
      "You can see how this excites our puzzlement.”
      "Ender Wiggin has been in this situation before. Back on Earth, the day he lost his monitor, and again when a large group of older boys--”
      "I did not come here ignorant of the past. Ender Wiggin has provoked Bonzo Madrid beyond human endurance. And you have no military police standing by to break up disturbances. It is unconscionable.”
      "When Ender Wiggin holds our fleets in his control, when he must make the decisions that bring us victory or destruction, will there be military police to came save him if things get out of hand?”
      "I fail to see the connection.”
      "Obviously. But the connection is there Ender Wiggin must believe that no matter what happens, no adult will ever, ever step in to help him in any way. He must believe, to the core of his soul, that he can only do what he and the other children work out for themselves. If he does not believe that, then he will never reach the peak of his abilities.”
      "He will also not reach the peak of his abilities if he is dead or permanently crippled.”
      "He won't be.”
      "Why don't you simply graduate Bonzo? He's old enough.”
      "Because Ender knows that Bonzo plans to kill him. If we transfer Bonzo ahead of schedule, he'll know that we saved him. Heaven knows Bonzo isn't a good enough commander to be promoted on merit.”
      "What about the other children? Getting them to help him?”
      "We'll see what happens. That is my first, final, and only decision.”
      "God help you if you're wrong.”
      "God help us all if I'm wrong.”
      "I'll have you before a capital court martial. I'll have your name disgraced throughout the world if you're wrong.”
      "Fair enough. But do remember if I happen to be right to make sure I get a few dozen medals.”
      "For what?”
      "For keeping you from meddling.”
     
      Ender sat in a corner of the battleroom, his arm hooked through a handhold watching Bean practice with his squad. Yesterday they had worked on attacks without guns, disarming enemies with their feet. Ender had helped them with some techniques from gravity personal combat --   many things had to be changed, but inertia in flight was a tool that could be used against the enemy as easily in nullo as in Earth gravity.
      Today, though, Bean had a new toy. It was a deadline, one of the thin, almost invisible twines used during construction in space to hold two objects together. Deadlines were sometimes kilometers long. This one was just a bit longer than a wall of the battleroom and yet it looped easily, almost invisibly, around Bean's wrist. He pulled it off like an article of clothing and handed one end to one of his soldiers.   "Hook it to a handhold and wind it around a few times." Bean carried the other end across the battleroom.
      As a tripwire it wasn't too useful, Bean decided. It was invisible enough, but one strand of twine wouldn't have much chance of stopping an enemy that could easily go above or below it. Then he got the idea of using it to change his direction of movement in midair. He fastened it around his waist, the other end still fastened to a handhold, slipped a few meters away, and launched himself straight out. The twine caught him, changed his direction abruptly, and swung him in an arc that crashed him brutally against the wall.
      He screamed and screamed. It took Ender a moment to realize that he wasn't screaming in pain. "Did you see how fast I went! Did you see how I changed direction!”
      Soon all of Dragon Army stopped work to watch Bean practice with the twine. The changes in direction were
