The character in "The Ionian Mission" presents a complex figure who is both a challenging patient and a notable medical authority. His assistants tend to leave him to his own devices, primarily focusing on his medical needs like dressings. His reputation as a physician, particularly in seamen's diseases, adds to his status, making him difficult to manage due to his high rank and expertise.

Despite his progressive views and criticism of authority, he exhibits a contradictory nature. His stubbornness and volatility often lead to aggressive responses when he is forced into a treatment regimen that he does not favor. This inconsistency illustrates the struggle between his liberal principles and a tendency toward authoritarian behavior when under pressure, especially in mundane situations.
