However, they are worried about Peter's reaction. Their concern, however, is tempered by the fact that they realize their job is not to make Ender happy but to save the world. The action returns to Ender's home, where his sister Valentine is comforting him over the loss of his monitor, although Ender does not seem to care. His brother Peter is angered by the fact that Ender had his monitor for longer than he did. Peter decides that he and Ender should play buggers and astronauts, a common children's game. However, Peter actually hurts Ender during the game, as he has in the past, treating his brother like a hated enemy. Even as Peter is preparing to do physical damage to him, Ender stops to think about what it really feels like to be a bugger, and what they think about humans. .
Peter, a full four years older than Ender, remarks out loud that he could kill Ender by slowly crushing the air out of his lungs with his knee and how everyone would think it was an accident. Ender does not think Peter is serious but knows it is possible. Valentine talks Peter out of it by pointing out that if he wants to enter politics he cannot have anything that looks this bad in his past, and he relents, although he tells her never to stop watching Ender because someday he will kill him. Peter goes even further, telling Valentine that it will look like an accident and she will not want to blame him. But, Peter says, he will kill Ender eventually.
Then Peter laughs about it all, claiming he was just messing around. Ender's parents come home, with very little to say, and it is clear that Ender cannot relate at all to them, except that he knows how awkward he makes them feel, since he is a Third, and he hates that feeling. Finally, while Ender is lying in bed at night, Peter comes to him, and at first Ender fears for his life. However, Peter apologizes, claiming that Ender is his brother and he loves him. Later, after Peter falls asleep, Ender cries again.
