But he knew this: He'd learn what he needed to learn. Opportunities would appear. And he, being Achilles, would see those opportunities and seize them. Nothing could interrupt his rise until he held all the power there was to hold within his hands. Then there would be perfect justice in the world, not this miserable system that left so many children starving and ignorant and crippled on the streets while others lived in privilege and safety and health. All those adults who had run things for thousands of years were fools or failures. But the universe obeyed Achilles. He and he alone could correct the abuses.

On his third day in Battle School, Rabbit Army had its first battle with Bean as commander. They lost. They would not have lost if Achilles had been commander. Bean was doing some stupid touchy-feely thing, leaving things up to the toon leaders. But it was obvious that the toon leaders had been badly chosen by Bean's predecessor. If Bean was to win, he needed to take tighter control. When he tried to suggest this to Bean, the child only smiled knowingly – a maddeningly superior smile – and told him that the key to victory was for each toon leader and, eventually, each soldier to see the whole situation and act independently to bring about victory. It made Achilles want to slap him, it was so stupid, so wrongheaded. The one who knew how to order things did not leave it up to others to create their little messes in the corners of the world. He took the reins and pulled, sharp and hard. He whipped his men into obedience. As Frederick the Great said: The soldier must fear his officers more than he fears the bullets of the enemy. You could not rule without the naked exercise of power. The followers must bow their heads to the leader. They must surrender their heads, using only the mind and will of the leader to rule them. No one but Achilles seemed to understand that this was the great strength of the Buggers. They had no individual minds, only the mind of the hive. They submitted perfectly to the queen. We cannot defeat the Buggers until we learn from them, become like them.

But there was no point in explaining this to Bean. He would not listen. Therefore he would never make Rabbit Army into a hive. He was working to create chaos. It was unbearable.

Unbearable – yet, just when Achilles thought he couldn't bear the stupidity and waste any longer, Bean called him to his quarters.

Achilles was startled, when he entered, to find that Bean had removed the vent cover and part of the wall panel, giving him access to the air-duct system. This was not at all what Achilles had expected.

"Take your clothes off," said Bean.

Achilles smelled an attempt at humiliation.

Bean was taking off his own uniform. "They track us through the uniforms," said Bean. "If you aren't wearing one, they don't know where you are, except in the gym and the battleroom, where they have really expensive equipment to track each warm body. We aren't going to either of those places, so strip."

Bean was naked. As long as Bean went first, Achilles could not be shamed by doing the same.

"Ender and I used to do this," said Bean. "Everybody thought Ender was such a brilliant commander, but the truth is he knew all the plans of the other commanders because we'd go spying through the air ducts. And not just the commanders, either. We found out what the teachers were planning. We always knew it in advance. Not hard to win that way."

Achilles laughed. This was too cool. Bean might be a fool, but this Ender that Achilles had heard so much about, he knew what he was doing.

"It takes two people, is that it?"

"To get where I can spy on the teachers, there's a wide shaft, pitch black. I can't climb down. I need somebody to lower me down and haul me back up. I didn't know who in Rabbit Army I could trust, and then ... there you were. A friend from the old days."

It was happening again. The universe, bending to his will. He and Bean would be alone. No one would be tracking where they were. No one would know what had happened.

"I'm in," said Achilles.

"Boost me up," said Bean. "You're tall enough to climb up alone."

Clearly, Bean had come this way many times before. He scampered through the crawl space, his feet and butt flashing in the spill from the corridor lights. Achilles noted where he put his hands and feet, and soon was as adept at Bean at picking his way through. Every time he used his leg, he marveled at the use of it. It went where he wanted it to go, and had the strength to hold him. Dr. Delamar might be a skilled surgeon, but even she said that she had never seen a body respond to the surgery as Achilles' did. His body knew how to be whole, expected to be strong. All the time before, those crippled years, had been the universe's way of teaching Achilles the unbearability of disorder. And now Achilles was perfect of body, ready to move ahead in setting things to rights.

Achilles very carefully noted the route they took. If the opportunity presented itself, he would be coming back alone. He could not afford to get lost, or give himself away. No one could know that he had ever been in the air system. As long as he gave them no reason, the teachers would never suspect him. All they knew was that he and Bean were friends. And when Achilles grieved for the child, his tears would be real. They always were, for there was a nobility to these tragic deaths. A grandeur as the great universe worked its will through Achilles's adept hands.

The furnaces roared as they came into a room where the framing of the station was visible. Fire was good. It left so little residue. People died when they accidentally fell into fire. It happened all the time. Bean, crawling around alone ... it would be good if they went near the furnace.

Instead, Bean opened a door into a dark space. The light from the opening showed a black gap not far inside. "Don't step over the edge of that," Bean said cheerfully. He picked up a loop of very fine cord from the ground. "It's a deadline. Safety equipment. Keeps workmen from drifting off into space when they're working on the outside of the station. Ender and I set it up – it goes over a beam up there and keeps me centered in the shaft. You can't grip it in your hands, it cuts too easily if it slides across your skin. So you loop it tight around your body – no sliding, see? – and brace yourself. The gravity's not that intense, so I just jump off. We measured it out, so I stop right at the level of the vents leading to the teachers' quarters."

"Doesn't it hurt when you stop?"

"Like a bitch," said Bean. "No pain no gain, right? I take off the deadline, I snag it on a flap of metal and it stays there till I get back. I'll tug on it three times when I get it back on. Then you pull me back up. But not with your hands. You go out the door and walk out there. When you get to place where we came in, go around the beam there and go till you touch the wall. Just wait there until I can get myself swinging and land back here on this ledge. Then I unloop myself and you come back in and we leave the deadline for next time. Simple, see?"

"Got it," said Achilles.

Instead of walking to the wall, it would be simple enough to just keep walking. Get Bean floating in the air where he couldn't get hold of anything. Plenty of time, then, to find a way to tie it off inside that dark room. With the roar of the furnaces and fans, nobody would hear Bean calling for help. Then Achilles would have time to explore. Figure out how to get into the furnaces. Swing Bean back, strangle him, carry the body to the fire. Drop the deadline down the shaft. Nobody would find it. Quite possibly no one would ever find Bean, or if they did, his soft tissues would be consumed. All evidence of strangulation would be gone. Very neat. There'd be some improvisation, but there always was. Achilles could handle little problems as they came up.
