Tom's character is a dynamic one, that is he moves from enjoyment in the most famous of boyhood games--playing "Indians and Chiefs," pretending to be Robin Hood, and so on--to actions that require a high degree of moral integrity. Consider, for example, his highly moral decision to break the boyish oath he took and to reveal Injun Joe's guilt in murdering Dr. Robinson--an act that freed an innocent man and placed Tom, himself, in jeopardy.
