Relationships
Huck is Tom Sawyer's closest friend. Their friendship is partially rooted in Sawyer's emulation of Huck's freedom and ability to do what he wants, like swearing and smoking when he feels like it. In one moment in the novel, he openly brags to his teacher that he was late for school because he stopped to talk with Huck Finn, something for which he knew he would (and did) receive a whipping. Nonetheless, Tom remains a devoted friend to Huck in all of the novels they appear in.
Jim, a runaway slave whom Huck befriends, is another dominant force in Huck's life. He is the symbol for the moral awakening Huck undergoes throughout Adventures of Huckleberry Finn.
Pap Finn is Huck's abusive, drunken father who shows up at the beginning of Adventures of Huckleberry Finn and forcibly takes his son to live with him. Pap's only method of parenting is physical abuse. Although he seems derisive of education and civilized living, Pap seems to be jealous of Huck and is infuriated that his son would try to amount to more and live in better conditions than he did.
