With Tom unable to direct the plans, Huck again takes control of the story and makes decisions based on his common sense and logic. Instead of listening to Tom's intricate plan to fetch a doctor, Huck trusts his own ability to tell lies and control the situation. Although the doctor is somewhat suspicious of Huck's story, when Huck returns to the farm, he finds that the entire community has been drawn into Tom's fanciful escape. The ignorance and gullibility of the farmers is easily seen as they try to reconstruct and understand the escape.
Jim's refusal to leave Tom in Chapter 40 becomes more significant in Chapter 42 when he allows himself to be recaptured. As with Huck's earlier decision to sacrifice his soul to free Jim, Jim sacrifices his freedom and, quite possibly, his life by staying with Tom. Because Jim is thought to be a runaway slave, the local men "was very huffy, and some of them wanted to hang Jim as an example." Jim is, no doubt, fully aware that if he is recaptured he might be lynched, and this realization gives more credence to his role as a heroic figure at the end of the novel. The doctor who saves Tom also lauds Jim's character, and this praise further establishes his position.
