Ender's Shadow

security had to be something else.
      It could still be that his earlier guess was partly right, and Battle School existed as much to strip the Earth of good commanders as to beat the Buggers. Graff and Dimak's fear might be that Bean would let other kids in on the secret. For some of them, at least, it might rekindle their loyalty to the nation or ethnic group or ideology of their parents.
      And since Bean had definitely been planning to probe the loyalties of other students over the next months and years, he now would have to be doubly cautious not to let his pattern of conversation attract the attention of the teachers. All he needed to know was which of the best and brightest kids had the strongest home loyalties. Of course, for that Bean would need to figure out just how loyalty worked, so he would have some idea of how to weaken it or strengthen it, how to exploit it or turn it.
      But just because this first guess of Bean's could explain their words didn't mean it was right. And just because the final Bugger war had not yet been fought didn't mean his initial guess was completely wrong. They might, for instance, have launched a fleet against the Bugger home world years ago, but were still preparing commanders to fight off an invasion fleet now approaching Earth. In that case, the security breach Graff and Dimak feared was that Bean would frighten others by letting them know how urgent and dire the situation of humanity was.
      The irony was that of all the children Bean had ever known, none could keep a secret as well as he did. Not even Achilles, for in refusing his share of Poke's bread, he had tipped his hand.
      Bean could keep a secret, but he also knew that sometimes you had to give some hint of what you knew in order to get more information. That was what had prompted Bean's conversation with Dimak. It was dangerous, but in the long run, if he could keep them from removing him from the school entirely in order to silence him -- not to mention keeping them from killing him -- he had learned more important information than he had given them. In the end, the only things they could learn from him were about himself. And what he learned from them was about everything else -- a much larger pool of knowledge.
      Himself. That was their puzzle -- who he was. Silly to be concerned about whether he was human. What else could he be? He had never seen any child show any desire or emotion that he himself had not felt. The only difference was that Bean was stronger, and did not let his fleeting needs and passions control his actions. Did that make him alien? He was human -- only better.
      The teacher came back into the room. He hung up his damp towel, but even before he dressed he sat back down and logged on. Bean watched his fingers move over the keys. It was so quick. A blur of keystrokes. He would have to replay the memory in his mind many times to make sure. But at least he had seen it; nothing obstructed his view.
      Bean crawled back toward the vertical intake shaft. The evening's expedition had already taken as long as he dared -- he needed his sleep, and every minute away increased the risk of chance discovery.
      In fact, he had been very lucky on this first foray through the ducts. To happen to hear Dimak and Graff conversing about him, to happen to watch a teacher who conveniently gave him a clear view of his log-in. For a moment it crossed Bean's mind that they might know he was in the air system, might even have staged all this for him, to see what he'd do. It might be just one more experiment.
      No. It wasn't just luck that this teacher showed him the log-in. Bean had chosen to watch him because he was going to shower, because his desk was sitting on the table in such a way that Bean had a reasonable chance of seeing the log-in. It was an intelligent choice on Bean's part. He had gone with the best odds, and it paid off.
      As for Dimak and Graff, it might have been chance that he overheard them talking, but it was his own choice to move closer at once in order to hear. And, come to think of it, he had chosen to go exploring in the ducts because of precisely the same event that had prompted Graff and Dimak to be so concerned. Nor was it a surprise that their conversation happened after lights-out for the children -- that's when things would have quieted down, and, with duties done, there would be time for a conversation without Graff calling Dimak in for a special meeting, which might
