So he wandered to the game room, where a few other boys were using the last half hour before final bell to settle bets or beat their previous scores on the games. None of the games looked interesting, but he played one anyway, an easy animated game designed for Launchies. Bored, he ignored the objectives of the game and used the little player-figure, a bear, to explore the animated scenery around him.
"You'll never win that way."
Ender smiled, "Missed you at practice, Alai."
"I was there. But they had your army in a separate place. Looks like you're big time now, can't play with the little boys anymore."
"You're a full cubit taller than I am."
"Cubit! Has God been telling you to build a boat or something? Or are you in an archaic mood?"
"Not archaic, just arcane. Secret, subtle, roundabout. I miss you already, you circumcised dog."
"Don't you know? We're enemies now. Next time I meet you in battle, I'll whip your ass."
It was banter, as always, but now there was too much truth behind it. Now when Ender heard Alai talk as if it were all a joke, he felt the pain of losing a friend, and the worse pain of wondering if Alai really felt as little pain as he showed.
"You can try," said Ender. "I taught you everything you know. But I didn't teach you everything I know."
"I knew all along that you were holding something back, Ender.
A pause. Ender's bear was in trouble on the screen. He climbed a tree. "I wasn't, Alai. Holding anything back."
"I know." said Alai. "Neither was I." "Salaam, Alai."
"Alas, it is not to be."
"What isn't?"
"Peace. It's what salaam means. Peace be unto you."
