"Don't talk about it, do it!" said Momoe. Then he took his own advice and ordered his boys to launch against the wall and rebound out behind the Dragon formation.
In the chaos of their takeoff, while Griffin Army held tight to their stars, the Dragon formation abruptly changed. Both the cylinder and the front wall split in two, as boys inside it pushed off; almost at once, the formations also reversed direction, heading back toward the Dragon gate. Most of the Griffins fired at the formations and the boys moving backward with them; and the Tigers took the survivors of Dragon Army from behind.
But there was something wrong. William Bee thought for a moment and realized what it was. Those formations couldn't have reversed direction in midflight unless someone pushed off in the opposite direction, and if they took off with enough force to make that twenty-man formation move backward, they must be going fast.
There they were, six small Dragon soldiers down near William Bee's own door. From the number of lights showing on their flash suits, Bee could see that three of them were disabled and two of them damaged; only one was whole. Nothing to be frightened of. Bee casually aimed at them, pressed the button, and--
Nothing happened. The lights went on. The game was over.
Even though he was looking right at them, it took Bee a moment to realize what had just happened. Four of the Dragon soldiers had their helmets pressed on the corners of the door. And one of them had just passed through. They had just carried out the victory ritual. They were getting destroyed, they had hardly inflicted any casualties, and they had the gall to perform the victory ritual and end the game right under their noses.
Only then did it occur to William Bee that not only had Dragon Army ended the game, it was possihie that, under the rules, they had won it. After all, no matter what happened, you were not certified as the winner unless you had enough unfrozen soldiers to touch the corners of the gate and pass someone through into the enemy's corridor. Therefore, by one way of thinking. you could argue that the ending ritual was victory. The battleroom certainly recognized it as the end of the game.
The teachergate opetied and Major Anderson came into the room. "Ender," he called, looking around.
One of the frozen Dragon soldiers tried to answer him through jaws that were clamped shut by the flash suit. Anderson hooked over to him and thawed him.
Ender was smiling. "I beat you again, sir," he said.
