Ponyboy starts off the novel as the most innocent member of the Greasers. He is the youngest of three brothers and has not yet experienced the degree of suffering the rest of the gang has. Ponyboy grows into more of an adult after talking with Cherry Valance and beginning to understand that everyone faces problems and people are not so different. By the end of the novel, after Ponyboy has witnessed the deaths of Bob Sheldon and Johnny, he has completely lost his innocence.
