"Locke and Demosthenes"

Graff is mad at Major Imbu, the computer expert, for Peter's image in Ender's game, and he has no idea, and says the computer is making up the program as it goes along. Back on Earth, Valentine hasn't forgot Ender, but Peter worries her, because he is evil and acts out of nothing but self-interest. Peter found out about the Warsaw Pact, which joined the nations together for the bugger wars, and that something's going on in space and the nations of earth are getting ready for what will result from it. Valentine realizes her and Peter can manipulate in their own ways, and Peter plans to work with Valentine to share political ideas over the nets (internet). Peter uses the pseudonym Locke, while Valentine uses the pseudonym Demosthenes, and their ideas begin to spread. Ender is 9 now, and he is the top ranked soldier and a platoon leader in Phoenix Army with Petra as commander, but he hates his life. Graff believes Ender needs help, and convinces Valentine to write Ender a letter showing that he's not like Peter. He becomes angry that the adults have taken his last memory from him by manipulating his sister to write a letter to make him happy again. He plays the mind game again, and the snake that he used to crush beneath his feet turned into his sister and they walk into the mirror, and behind it, there is a stairway that Ender and Valentine walk down. Ender ends up happy, knowing that Valentine will always be there for him.

While reading, I noticed that just like how Peter's in Ender, he's in Valentine as well. Valentine goes along with Peter only because she knows that they can make a difference in the changing world they live in. Graff is the only person who sees the three Wiggin children as intellectual equals, and Ender's anger increases when he gets the letter, which makes him do things he hasn't done before in the mind game, which is what he does throughout the book when he exceeds what he thought were his limits.
