When Huck and Jim first encounter the King and the Duke, the two rogues are working together to come up with ways in which to scam the small town citizens out of their money. They play off of each other and work together to build up their "back story" and to convince others of their lineage and knowledge in certain areas. However, this all changes after the four leave Mary Jane and her family. Once back on the raft the Duke and the King begin arguing and accusing each other of attempting to steal the bag of money from the Wilkes' residence. This is markedly different from earlier because now the two have become suspicious and accusatory of each other, whereas before they were working together. They are particularly mean to Huck and Jim at this time as well.
