Graff notices that Ender is having a rough time so he allows him to go back to Earth to hide out at a lake house. He knows how much Ender loved his sister and that he missed her tremendously. Graff picked Valentine up from school to take her to go see Ender. Even Though Ender claimed he did not want to see her, he knew deep down he appreciated it. It was a very nice thing of Graff to do for Ender and Valentine. “Childhood stars shine, always stay humble and kind” are lyrics that correlate well with this situation because Ender and Valentine are still kids. Graff swallowed his tough side and bend the rules a little. Valentine notices because she says “I thought you told me last time he would be eligible for leave when he was sixteen.”
