Now, we know that Ender thinks that he’s Bean’s secret friend. But the end of Chapter 11 is the first time that Bean realizes that he’s Ender’s friend. What makes Bean realize this is that Ender shows his, ahem, softer side – that he’s not just an invulnerable commander, but he’s really a vulnerable kid. Also, they have a sleepover, which drives home the point that they’re friends. This is a bit odd, because Ender can’t be friends with any of this other soldiers, so why can he be friends with Bean? Why can he show Bean that he’s vulnerable?
