1. Chapter nine is a very interesting chapter. It first starts off with Graff getting mad about Peter showing up in Ender's video game. He does not understand why and needs to find out why the computer would a picture of Peter into Ender's fairyland. So, he ends up going back down to earth to find out why the computer would do such a thing. Colonel Graff goes to Valentines new school in Greensboro, the new place there family moved to. He tries to get answers out of Valentine about Peter and about their life with Ender before he went up to battle school. But Valentine doesn't budge so, Colonel Graff makes Valentine write a letter to Ender saying that he is nothing like Peter and that he was a good person and not a bad one. But, Ender knows that Valentine wouldn't write like that and he finds out that his teachers made Valentine write it and that it wasn't a letter from the heart. Ender still knows that Valentine loved him but, he knew that she did not write with love in this letter.
The next major event that occurred in chapter nine was with Valentine and Peter. The main point of the chapter was about Peter and Valentine and how they made fake identities as adults to express how they feel about the world. Valentine and Peter become much closer and spend much more time together as siblings. Valentine's secret identity is Demosthenes and Peter's is Locke. Demosthenes was an old greek statesman and orator of ancient Athens and Locke was an english philosopher and physician. They chose these people so they could take over the world before the world wars start to break out since there is not going to be another war against the Bugger's. This is the only way to do it in Peter's mind.
