Does Huck still believe in superstition by the end of his journey?
Towards the end of Huck’s journey, Tom Sawyer shows up to complicate things. There is a great deal of focus on Tom’s bizarre plots and lies, with which Huck is complicit. Huck reverts back to a follower of Tom’s, losing much of the innocence he had while on the raft, so his superstitions are not as pronounced as they were when he was only with Jim. When Huck and Jim were alone on the journey, Huck had all sorts of his own superstitions and accepted a lot of Jim’s as well, even though he thought many of Jim’s were the foolish rantings of a slave. Just in case they might be true, though, Huck indulged Jim’s superstitions.
When Tom shows up, we see less of these superstitions and more of the bizarre plans and lies. However, Huck and Tom do plan to make a “witch pie”, which shows they still have some superstitions, and when Jim receives the $40 from Tom, he says it is all because of the good luck of his hairy chest. Plus, when Tom is shot in the bizarre escape attempt, he later keeps the bullet in a chain around his neck, supposedly for good luck. Superstition seems to still be part of the plot, just not as pronounced, because Huck is back in civilization now and along with that, he has put away a lot of his erstwhile superstitions.
