Chapter One reveals several important details about Ender's siblings.  First, the reader learns that Ender is a 'third,' meaning that he has two older siblings; families are only supposed to have two children, so Ender's status as a third makes him somewhat of an outcast.  One of Ender's siblings is an older brother named Peter, who Ender fears.  When having the monitor removed, Ender experiences relief that perhaps with the device gone, Peter will no longer hate him.  This opening characterization clearly reveals not only the inequity in the relationship, but also reinforces a very negative portrayal of Peter; Card portrays him as a jealous character with implied violent tendencies. In the final scene, Ender fears becoming like Peter after winning the fight with Stilson.
