In Patrick O'Brian's "The Thirteen-Gun Salute," Stephen experiences notable irritation while ascending to the maintop, which impacts his usual instinct for caution and dread in such situations. This emotional state stands out against his typical careful demeanor. His friend Jack observes this change and comments on Stephen's ability to navigate the rigging with the skill of an experienced sailor, highlighting Stephen's contrasting feelings and adaptability.

The exchange between Jack and Stephen reflects the camaraderie and understanding between the two characters. Jack's initial instinct was to compare Stephen's climbing skills to those of a human being, but he quickly adjusts his words to better flatter Stephen's capabilities. This moment captures the theme of friendship and the growth of confidence as Stephen navigates his emotions while tackling challenges at sea.
