James Castle is a student Holden knew when he was still attending Elkton Hills. Holden has an odd respect for Castle because Castle committed suicide by jumping out of his window after refusing to submit to a group of bullies who locked Castle and themselves with in Castle’s room. For some reason, Holden thinks of Castle when Phoebe asks him to name just one thing he genuinely likes—a sign that he admires both Castle’s unwillingness to give in to bullies and the fact that he committed suicide, which is something Holden himself often thinks about.
