Besides having a brother who wants to kill him, parents who feel conflicted about him, a teacher who lies to him, and an alien species that might want to destroy his planet, Ender’s big problem is that he has no friends. Actually, having no friends is probably one of Ender’s biggest problems – all of the other problems are bearable, if only Ender has a friend to help him through it. Seriously. In Ender's Game, having a crazy brother is only OK because Ender has his sister’s love and companionship. If Val wasn’t there for him, Ender might not have made it. Similarly, if Ender didn’t have Alai and Shen, then he might not have gotten through Battle School sane. Ender may be a kid who has trouble making and keeping friends, but he desperately needs them, too.
