Coming of Age and self-discovery are major themes. As the story begins, young Hawkins lives in a small village and works each day in his parents' inn. He is devoted to his parents and at first afraid of the pirate Billy Bones. Hawkins trembles when Bones touches him. Hawkins is also somewhat naïve, trusting other people's interpretations rather than trusting his own. For example, when Hawkins recognizes a pirate in Long John Silver's inn, he believes Silver when he says he has no idea who the man is.
Hawkins' gullibility slowly fades as the adventure progresses and his experiences widen. For instance, when Hawkins climbs into the apple barrel and overhears Silver planning a mutiny, he begins to understand that there is real evil in the world. As the story continues, there are more rites of passage as Hawkins passes through adolescence to adulthood. He sneaks off the ship once it is anchored and takes off on a journey all by himself. He fights in a battle against the pirates and sees many men die. He conjures up a plan to rescue the ship from the pirates. At this point he feels the full strength of his power. He tells the only conscious pirate onboard that he, Hawkins, should be referred to as the captain of the ship. It is as if Hawkins is stating he is a man. He orders the pirate to help him steer the ship through dangerous currents and anchor the boat in a safe harbor. At the end of this scene, Hawkins receives his first wound. It is a superficial cut, but with it Hawkins faces his own mortality.
