“[That wall] might be breached sometime in the future, but for now the only real conversation between them was the roots that had already grown low and deep, under the wall, where they could not be broken.The most terrible thing, though, was the fear that the wall could never be breached, that in his heart Alai was glad of the separation, and was ready to be Ender's enemy. For now that they could not be together, they must be infinitely apart, and what had been sure and unshakable was now fragile and insubstantial; from the moment we are not together, Alai is a stranger, for he has a life now that will be no part of mine, and that means that when I see him we will not know each other.”

“...He found himself filled with joy, for now his existence had a meaning. He had a future, because he was part of a world that had a future, and instead of wanting to decide for himself and determine that future for everyone else, he knew that he would be glad just to touch some small part of it. To marry and give happiness to his wife. To have a child and give it the same love that his parents gave him. To have a friend and ease his burdedn now and then. To have a skill or a secret and teach it to a student whose life might be changed a little by what he learned. Why had he dreamed of leading armies, whichwould accomplish nothing, when he could do these miraculous small things and change the world?”

“If only we could have talked to you, the hive-queen said in Ender's words. But since it could not be, we ask only this: that you remember us, not as enemies, but as a tragic sisters, changed into foul shape by fate or God or evolution. If we had kissed, it would have been the miracle to make us human in each other's eyes. Instead we killed each other. But still we welcome you now as guestfriends. Come into our home, daughters of Earth; dwell in our tunnels, harvest our fields; what we cannot do, you are now our hands to do for us. Blossom, trees; ripen, fields; be warm for them, suns; be fertile for them, planets: they are our adopted daughters, and they have come home.”

“What am I now, Alai?""Still good.""At what?""At--anything. There's a million soldiers who'd follow you to the end of the universe.""I don't want to go to the end of the universe.""So where do you want to go? They'll follow you."I want to go home, thought Ender, but I don't know where it is.”

“For the first time in his life, a teacher was pointing out things that Ender had not already seen for himself. For the first time, Ender had found a living mind he could admire.”

“An enemy, Ender Wiggin," whispered the old man. "I am your enemy, the first one you've ever had who was smarter than you. There is no teacher but the enemy. No one but the enemy will tell you what the enemy is going to do. No one but the enemy will ever teach you how to destroy and conquer. Only the enemy shows you where you are weak. Only the enemy tells you where he is strong. And the rules of the game are what you can do to him and what you can stop him from doing to you. I am your enemy from now on. From now on I am your teacher.”

And the only rules of the game are what you can do to him and what you can stop him from doing to you. I am your enemy from now on. From now on I am your teacher. I will devise the strategy of your army, and you will learn to be quick and discover what tricks the enemy has for you. Remember, boy. From now on the enemy is more clever than you. From now on the enemy is stronger than you. From now on you are always about to lose.”
