"What if somebody's using the room? We alway's went right after breakfast, in my launch."
"No problem. There are really nine battlerooms."
"I never heard of any others."
"They all have the same entrance. The whole center of the battle school, the hub of the wheel, is battlerooms. They don't rotate with the rest of the station.

Once you're inside, they move it along and another battleroom's in position."
"Oh."
"Like I said. Right after breakfast."

Ender thanked him and started to walk on past.
"Hey," said the boy. "You can't go like that. Uniforms at all times out of this room." "Even going to the toilet?"
