The doctor was twisting something at the back of Ender's head. Suddenly a pain stabbed through him like a needle from his neck to his groin. Ender felt his back spasm, and his body arched violently backward; hi head struck the bed. He could feel his legs thrashing, and his hands were clenching each other, wringing each other so tightly that they ached.

"Deedee!" shouted the doctor. "I need you!" The nurse ran in, gasped. "Got to relax these muscles. Get it to me, now! What are you waiting for!"

Something changed hands; Ender could not see. He lurched to one side and fell off the examining table. "Catch him!" cried the nurse.

"Just hold him steady."

"You hold him, doctor, he's too strong for me."

"Not the whole thing! You'll stop his heart."

Ender felt a needle enter his back just above the neck of his shirt. It burned, but wherever in him the fire spread, his muscles gradually unclenched. Now he could cry for the fear and pain of it.

"Are you all right, Andrew?" the nurse asked.

Andrew could not remember how to speak. They lifted him onto the table. They checked his pulse, did other things; he did not understand it all.

The doctor was trembling; his voice shook as he spoke. "They leave these things in the kids for three years, what do they expect? We could have switched him off, do you realize that? We could have unplugged his brain for all time."

"When does the drug wear off'?" asked the nurse.

"Keep him here for at least an hour. Watch him. If he doesn't start talking in fifteen minutes, call me. Could have unplugged him forever. I don't have the brains of a bugger."

He got back to Miss Pumphrey's class only fifteen minutes before the closing bell. He was still a little unsteady on his feet.

"Are you all right, Andrew?" asked Miss Pumphrey.
