"Dragon"

Graff tells Anderson to make Ender a commander, and he agrees, saying he has been playing well and happy lately. They make him the commander of Dragon Army, with mostly untrained launchies with several veterans, who weren't skilled, without being able to trade them. He trains his army, and he notices a boy named Bean is very good. He does the same thing Graff did to him to Bean, to make him the best soldier he could be. Anderson tells Ender that he can't have his extra practices anymore, and Ender realizes things have to be different now that he's a commander, even with Alai. He also realizes that the teachers can't hurt him, since they went so low as to use Valentine on him, and he's out to defeat them for that.

While reading, I noticed Ender became more like Graff, as he was promoted to commander. He treats his army like how the adults have been manipulating him. This shows how hard it is to take responsibility in a military environment, especially for Ender, since he's losing everything.
