Ender's Game (Ender Wiggins Saga)

maneuvering.
      So everything depends on how you push off, the course you set when you start. It means we're going to have to get very good at controlling our launches and rebounds or we're all going to end up floating around in the middle of nowhere. Ender looked around the room. A few of the boys were drifting close to walls now, flailing their arms to catch a handhold. Most were bumping into each other and laughing; some were holding hands and going around in circles. Only a few, like Ender, were calmly holding onto the walls and watching.
      One of them, he saw, was Alai. He had ended up on another wall not too far from Ender. On impulse, Ender pushed off and moved quickly toward Alai. Once in the air, he wondered what he would say. Alai was Bernard's friend. What did Ender have to say to him?
      Still, there was no changing course now. So he watched straight ahead, and practiced making tiny leg and hand movements to control which way he was facing as he drifted. Too late, he realized that he had aimed too well. He was not going to land near Alai-- he was going to hit him.
      "Here, snag my hand!" Alai called.
      Ender held out his hand. Alai took the shock of impact and helped Ender make a fairly gentle landing against the wall.
      "That's good," Ender said. "We ought to practice that kind of thing.”
      "That's what I thought, only everybody's turning to butter out there," Alai said. "What happens if we get out there together? We should be able to shove each other in opposite directions.”
      "Yeah.”
      "OK?”
      It was an admission that all might not be right between them. Is it OK for us to do something together? Ender's answer was to take Alai by the wrist and get ready to push off.
      "Ready?" said Alai. "Go.”
      Since they pushed off with different amounts of force, they began to circle each other. Ender made some small hand movements, then shifted a leg. They slowed. He did it again. They stopped orbiting. Now they were drifting evenly.
      "Packed head, Ender." Alai said. It was high praise. "Let's push off before we run into that bunch.”
      "And then let's meet over in that corner." Ender did not want this bridge into the enemy camp to fail.
      "Last one there saves farts in a milk bottle," Alai said.
      Then, slowly, steadily, they maneuvered until they faced each other, spread-eagled, hand to hand, knee to knee.
      "And then we just scrunch?" asked Alai.
      "I've never done this before either," said Ender.
      They pushed off. It propelled them faster than they expected. Ender ran into a couple of boys and ended up on a wall that he hadn't expected. It took him a moment to reorient and find the corner where he and Alai were to meet. Alai was already headed toward it. Ender plotted a course that would include two rebounds, to avoid the largest clusters of boys.
      When Ender reached the corner, Alai had hooked his arms through two adjacent handholds and was pretending to doze.
      "You win.”
      "I want to see your fart collection," Alai said.
      "I stored it in your locker. Didn't you notice?”
      "I thought it was my socks.”
      "We don't wear socks anymore.”
      "Oh yeah." A reminder that they were both far from home. It took some of the fun out of having mastered a bit of navigation.
      Ender took his pistol and demonstrated what he had learned about the two thumb buttons.
      "What does it do when you aim at a person?" asked Alai.
      "I don't know.”
      "Why don't we find out?”
      Ender shook his head. "We might hurt somebody.”
      "I meant why don't we shoot each other in the foot or something. I'm not Bernard, I never tortured cats for fun.”
      "Oh.”
      "It can't be too dangerous, or they wouldn't give these guns to kids.”
      "We're soldiers now.”
      "Shoot me in the foot.”
      "No, you shoot me.”
      "Let's shoot each other.”
      They did. Immediately Ender felt the leg of the suit grow stiff, immobile at the knee and ankle joints.
      "You frozen?" asked Alai.
      "Stiff as a board.”
      "Let's freeze a few," Alai said. "Let's have our first war. Us against them.”
      They grinned. Then Ender said, "Better invite Bernard.”
      Alai cocked an eyebrow. "Oh?”
      "And Shen.”
      "That little slanty-eyed butt-wiggler?”
      Ender decided that Alai was joking. "Hey, we can't all be niggers.”
      Alai grinned. "My grandpa would've killed you for that.”
      "My great great grandpa would have sold him first,”
      "Let's go
