Andy Barbour became friends with Theo in elementary school, when they were both moved up a grade and mercilessly bullied for it. Andy is incredibly smart and nerdy, with an off-putting, “robotic” manner. He struggles with feeling as if he doesn’t fit in with his preppy, elegant, outdoorsy family. Andy’s brother Platt bullies him and his parents are trying to turn him into a different kind of person. Although Theo sees Andy for the last time in childhood, he later hears that Andy had a successful career, gaining a prestigious fellowship at M.I.T. and getting engaged to a Japanese woman. However, tragically Andy is killed in a sailing accident along with his father, Mr. Barbour, when he is still only in his 20s.
