Ender's Shadow

clothing and beds. Power wasn't about access to food-it was about getting the approval of adults.
      That's what those uniforms meant. Adults chose them, and children wore them because adults somehow made it worth their while.
      So the key to everything was understanding the teachers.
      All this passed through Bean's mind, not so much verbally as with a clear and almost instantaneous understanding that within that crew there was no power at all, compared to the power of the teachers, before the uniformed catcallers reached him. When they saw Bean, so much smaller than any of the other kids, they broke out laughing, hooting, howling. "That one isn't big enough to be a turd!" "I can't believe he can walk!" "Did'ums wose um's mama?" "Is it even human?”
      Bean tuned them out immediately. But he could feel the enjoyment of the kids ahead of him in line. They had been humiliated in the shuttle; now it was Bean's turn to be mocked. They loved it. And so did Bean-because it meant that he was seen as less of a rival. By diminishing him, the passing soldiers had made him just that much safer from ...
      From what? What was the danger here?
      For there would be danger. That he knew. There was always danger. And since the teachers had all the power, the danger would come from them. But Dimak had started things out by turning the other kids against him. So the children themselves were the weapons of choice. Bean had to get to know the other kids, not because they themselves were going to be his problem, but because their weaknesses, their desires could be used against him by the teachers. And, to protect himself, Bean would have to work to undercut their hold on the other children. The only safety here was to subvert the teachers' influence. And yet that was the greatest danger -- if he was caught doing it.
     
     
      They palmed in on a wall-mounted pad, then slid down a pole -- the first time Bean had ever done it with a smooth shaft. In Rotterdam, all his sliding had been on rainspouts, signposts, and lightpoles. They ended up in a section of Battle School with higher gravity. Bean did not realize how light they must have been on the barracks level until he felt how heavy he was down in the gym.
      "This is just a little heavier than Earth normal gravity," said Dimak. "You have to spend at least a half-hour a day here, or your bones start to dissolve. And you have to spend the time exercising, so you keep at peak endurance. And that's the key -- endurance exercise, not bulking up. You're too small for your bodies to endure that kind of training, and it fights you here. Stamina, that's what we want.”
      The words meant almost nothing to the kids, but soon the trainer had made it clear. Lots of running on treadmills, riding on cycles, stair-stepping, pushups, situps, chinups, backups, but no weights. Some weight equipment was there, but it was all for the use of teachers. "Your heartrate is monitored from the moment you enter here," said the trainer. "If you don't have your heartrate elevated within five minutes of arrival and you don't keep it elevated for the next twenty-five minutes, it goes on your record and I see it on my control board here.”
      "I get a report on it too," said Dimak. "And you go on the pig list for everyone to see you've been lazy.”
      Pig list. So that's the tool they used -- shaming them in front of the others. Stupid. As if Bean cared.
      It was the monitoring board that Bean was interested in. How could they possibly monitor their heartrates and know what they were doing, automatically, from the moment they arrived? He almost asked the question, until he realized the only possible answer: The uniform. It was in the clothing. Some system of sensors. It probably told them a lot more than heartrate. For one thing, they could certainly track every kid wherever he was in the station, all the time. There must be hundreds and hundreds of kids here, and there would be computers reporting the whereabouts, the heartrates, and who could guess what other information about them. Was there a room somewhere with teachers watching every step they took?
      Or maybe it wasn't the clothes. After all, they had to palm in before coming down here, presumably to identify themselves. So maybe there were special sensors in this room.
      Time to find out. Bean raised his hand. "Sir," he said.
      "Yes?" The trainer did a doubletake on seeing Bean's size, and a smile played around the corners of his
