"Especially. And you're forbidden to speak to anyone from any other army. At meals or in the toilet. You can get away with it sometimes in the game room, and of course whenever a teacher tells you to, but if Bonzo catch you, you dead, eh?"

"Thanks."

"And, uh, Bonzo get mad if you skin by Petra."

"She was naked when I came in, wasn't she?"

"She do what she like, but you keep you clothes on. Bonzo's orders."

That was stupid. Petra still looked like a boy, it was a stupid rule. It set her apart, made her different, split the army. Stupid stupid. How did Bonzo get to be a commander, if he didn't know better than that? Alai would be a better commander than Bonzo. He knew how to bring a group together.

I know how to bring a group together, too, thought Ender. Maybe I'll be commander someday.

In the bathroom, he was washing his hands when somebody spoke to him. "Hey, they putting babies in Salamander uniforms now?"

Ender didn't answer just dried off his hands.

"Hey, look! Salamander's getting babies now! Look at this! He could walk between my legs without touching my b.a.l.l.s!"

"Cause you got none, d.i.n.k, that's why," somebody answered.

As Ender left the room, he heard somebody else say, "It's Wiggin. You know, the smarta.s.s from the game room."

He walked down the corridor smiling. He may be short, but they knew his name. From the game room, of course, so it meant nothing. But they'd see. He'd be a good soldier, too. They'd all know his name soon enough. Not in Salamander Army, maybe, but soon enough.

Petra was waiting in the corridor that led to the battleroom. "Wait a minute," she said to Ender. "Rabbit Army just went in, and it takes a few minutes to change to the next battleroom."

Ender sat down beside her. "There's more to the battleroom than just switching from one to the next," he said. "For instance, why is there gravity in the corridor outside the room, just before we go in?"

Petra closed her eyes. "And if the battlerooms are really free-floating, what happens when one is connected? Why doesn't it start to move with the rotation of the school?"

Ender nodded.

"These are the mysteries," Petra said in a deep whisper. "Do not pry into them. Terrible things happened to the last soldier who tried. He was discovered hanging by his feet from the ceiling of the bathroom, with his head stuffed in the toilet."

"So I'm not the first person to ask the question."

"You remember this, little boy." When she said little boy it sounded friendly, not contemptuous. "They never tell you any more truth than they have to. But any kid with brains knows that there've been some changes in science since the days of old Mazer Rackham and the Victorious Fleet. Obviously we can now control gravity. Turn it on and off, change the direction, maybe reflect it-- I've thought of lots of neat things you could do with gravity weapons and gravity drives on starships. And think how starships could move near planets. Maybe tear big chunks out of them by reflecting the planet's own gravity back on itself, only from another direction, and focused down to a smaller point. But they say nothing."

Ender understood more than she said. Manipulation of gravity was one thing; deception by the officers was another; but the most important message was this: the adults are the enemy, not the other armies. They do not tell us the truth.

"Come, little boy," she said. "The battleroom is ready. Petra's hands are steady. The enemy is deadly." She giggled. "Petra the poet, they call me."

"They also say you're crazy as a loon."

"Better believe it, baby b.u.t.t." She had ten target b.a.l.l.s in a bag. Ender held onto her suit with one hand and the wall with the other, to steady her as she threw them, hard, in different directions. In the null gravity, they bounced every which way. "Let go of me," she said. She shoved off, spinning deliberately; with a few deft hand moves she steadied herself, and began aiming carefully at ball after ball. When she shot one, its glow changed from white to red. Ender knew that the color change lasted less than two minutes. Only one ball had changed back to white when she got the last one.

She rebounded accurately from a wall and came at high speed back to Ender. He caught her and held her against her own rebound, one of the first techniques they had taught him as a Launchy.

"You're good," he said.

"None better. And you're going to learn how to do it."

Petra taught him to hold his arm straight, to aim with the whole arm. "Something most soldiers don't realize is that the farther away your target is, the longer you have to hold the beam within about a two-centimeter circle. It's the difference between a tenth of a second and a half a second, but in battle that's a long time. A lot of soldiers think they missed when they were right on target, but they moved away too fast. So you can't use your gun like a sword, swish swish slice-em-in-half. You got to aim."

She used the ballcaller to bring the targets back, then launched them slowly, one by one. Ender fired at them. He missed every one.

"Good," she said. "You don't have any bad habits."

"I don't have any good ones, either," he pointed out.

"I give you those."

They didn't accomplish much that first morning. Mostly talk. How to think while you were aiming. You've got to hold your own motion and your enemy's motion in your mind at the same time. You've got to hold your arm straight out and aim with your body, so in case your arm is frozen you can still shoot. Learn where your trigger actually fires and ride the edge, so you don't have to pull so far each time you fire. Relax your body, don't tense up; it makes you tremble.

It was the only practice Ender got that day. During the army's drills in the afternoon, Ender was ordered to bring his desk and do his schoolwork, sitting in a corner of the room. Bonzo had to have all his soldiers in the battleroom, but he didn't have to use them.

Ender did not do his schoolwork, however. If he couldn't have drill as a soldier, he could study Bonzo as a tactician. Salamander Army was divided into the standard four toons of ten soldiers each. Some commanders set up their toons so that A toon consisted of the best soldiers, and D toon had the worst. Bonzo had mixed them, so that each consisted of good soldiers and weaker ones.

Except that B toon had only nine boys. Ender wondered who had been transferred to make room for him. It soon became plain that the leader of toon B was new. No wonder Bonzo was so disgusted-- he had lost a toon leader to get Ender.

And Bonzo was right about another thing. Ender was not ready.

All the practice time was spent working on maneuvers. Toons that couldn't see each other practiced performing precision operations together with exact timing; toons practiced using each other to make sudden changes of direction without losing formation. All these soldiers took for granted skills that Ender didn't have. The ability to make a soft landing and absorb most of the shock. Accurate flight. Course adjustment using the frozen soldiers floating randomly through the room. Rolls, spins, dodges. Sliding along the walls-- a very difficult maneuver and yet one of the most valuable, since the enemy couldn't get behind you.

Even as Ender learned how much he did not know, he also saw things that he could improve on. The well-rehea.r.s.ed formations were a mistake. It allowed the soldiers to obey shouted orders instantly, but it also meant they were predictable. Also, the individual soldiers were given little initiative. Once a pattern was set, they were to follow it through. There was no room for adjustment to what the enemy did against the formation. Ender studied Bonzo's formations like an enemy commander would, noting ways to disrupt the formation.

During free play that night, Ender asked Petra to practice with him.

"No," she said. "I want to be a commander someday, so I've got to play the game room." It was a common belief that the teachers monitored the games and spotted potential commanders there. Ender doubted it, though. Toon leaders had a better chance to show what they might do as commanders than any video player.

But he didn't argue with Petra. The after-breakfast practice was generous enough. Still, he had to practice. And he couldn't practice alone, except a few of the basic skills. Most of the hard things required partners or teams. If only he still had Alai or Shen to practice with.

Well, why shouldn't he practice with them? He had never heard of a soldier practicing with Launchies, but there was no rule against it. It just wasn't done; Launchies were held in too much contempt. Well, Ender was still being treated like a Launchy anyway. He needed someone to practice with, and in return he could help them learn some of the things he saw the older boys doing.

"Hey, the great soldier returns!" said Bernard. Ender stood in the doorway of his old barracks. He'd only been away for a day, but already it seemed like an alien place, and the others of his launch group were strangers. Almost he turned around and left. But there was Alai, who had made their friendship sacred. Alai was not a stranger.

Ender made no effort to conceal how he was treated in Salamander Army. "And they're right. I'm about as useful as a sneeze in a s.p.a.cesuit." Alai laughed, and other Launchies started to gather around. Ender proposed his bargain. Free play, every day, working hard in the battleroom, under Ender's direction. They would learn things from the armies, from the battles Ender would see; he would get the practice he needed in developing soldier skills. "We'll get ready together."

A lot of boys wanted to come, too. "Sure," Ender said. "If you're coming to work. If you're just farting around, you're out. I don't have any time to waste."

They didn't waste any time. Ender was clumsy, trying to describe what he had seen, working out ways to do it. But by the time free play ended, they had learned some things. They were tired, but they were getting the knack of a few techniques.

"Where were you?" asked Bonzo.

Ender stood stiffly by his commander's bunk. "Practicing in a battleroom."
