So Ender walked to Stilson's supine body and kicked him again, viciously, in the ribs. Stilson groaned and rolled away from him. Ender walked around him and kicked him again, in the crotch. Stilson could not make a sound; he only doubled up and tears streamed out of his eyes.

Then Ender looked at the others coldly. "You might be having some idea of ganging up on me. You could probably beat me up pretty bad. But just remember what I do to people who try to hurt me. From then on you'd be wondering when I'd get you, and how bad it would be." He kicked Stilson in the face. Blood from his nose spattered the ground nearby. "It wouldn't be this bad," Ender said. "It would be worse."

He turned and walked away. Nobody followed him, He turned a corner into the corridor leading to the bus stop. He could hear the boys behind him saying, "Geez. Look at him. He's wasted." Ender leaned his head against the wall of the corridor and cried until the bus came. I am just like Peter. Take my monitor away, and I am just like Peter.

Ender shook his head. He had expected someone from the school to come about Stilson, not an officer of the fleet. This was more serious than he had thought. And yet he couldn't think what else he could have done.

"Do you have any explanation for your behavior, young man?" asked the officer. Ender shook his head again. He didn't know what to say, and he was afraid to reveal himself to be any more monstrous than his actions had made him out to be. I'll take it, whatever the punishment is, he thought. Let's get it over with.

"We're willing to consider extenuating circumstances," the officer said. "But I must tell you it doesn't look good. Kicking him in the groin, kicking him repeatedly in the face and body when he was down-- sounds like you really enjoyed it."
"I didn't," Ender whispered.
"Then why did you do it?"
"He had his gang there," Ender said.
"So? This excuses anything?"
"No."
"Tell me why you kept on kicking him. You had already won."
"Knocking him down won the first fight. I wanted to win all the next ones, too, right then, so they'd leave me alone."

Ender couldn't help it, he was too afraid, too ashamed of his own acts: though he tried not to, he cried again. ...

There was no doubt now in Ender's mind. There was no help for him. Whatever he faced, now and forever, no one would save him from it. Peter might be scum, but Peter had been right, always right; the power to cause pain is the only power that matters, the power to kill and destroy, because if you can't kill then you are always subject to those who can, and nothing and no one will ever save you.

Dink led him to his room, made him lie on the bed. "Are you hurt anywhere?" he asked,
Ender shook his head.
"You took him apart. I thought you were dead meat, the way he grabbed you. But you took him apart. If he'd stood up longer, you would've killed him."
"He meant to kill me."
...
All Ender could see, though, was the way Bonzo looked as Ender kicked upward into his groin. The empty, dead look in his eyes. He was already finished then. Already unconscious. His eyes were open, but he wasn't thinking or moving anymore, just that dead, stupid look on his lace, that terrible look, the way Stilson looked when I finished with him.
...
Then, to Dink's surprise, Ender began to cry. Lying on his back, still soaking wet with sweat and water, he gasped his sobs, tears seeping out of his closed eyelids and disappearing in the water on his face.
"Are you all right?"
"I didn't want to hurt him!" Ender cried. "Why didn't he just leave me alone!"
...

He heard his door open softly, then close. He knew at once that it was his battle instructions, He opened his eyes, expecting to find the darkness of early morning, before 0600. Instead, the lights were on, He was naked and when he moved the bed was soaking wet, His eyes were puffy and painful from crying. He looked at the clock on his desk. 1820, it said. It's the same day. I already had a battle today, I had two battles today – the bastards know what I've been through, and they're doing this to me.
