it was a "magic" hairball from the belly of an animal
Jim is initially startled when he sees Huck on the island, as he believes that he has seen a ghost. However, he quickly realizes that Huck is alive and is relieved to be reunited with him. Jim is happy to see Huck safe and well.
Jim believes that Huck is a ghost because he previously thought that Huck had died. Huck's unexpected return led Jim to believe that he had come back as a ghost. This reflects Jim's superstitious beliefs and fear of the supernatural.
Huck thought it a derangement of Jim ethical character to think to steal another man's property.
Jim was initially startled and suspicious when he saw Huck for the first time as he was afraid Huck would turn him in. However, he eventually realized that Huck genuinely wanted to help him escape, which led to a deep bond of friendship developing between the two characters.
Huck is upset when Jim is sold because they had a great relationship. Huck knew that he was Jim's one and only best friend and also Huck looked to him as much as a brother and he did a friend, despite their races.
Huck feels free to tease Jim because of the societal norms and racial attitudes of the time that diminished the humanity of African Americans like Jim. Huck, being a product of his environment, does not fully comprehend the impact of his actions on Jim due to his own privilege as a white person.
I thought that Huck was making a big mistake. Huck isn't the type of person who would purposely betray Jim. Huck always tries to do what is right, even if he isn't sure what that is. He would have ended up regretting sending that letter if Jim had been captured. He would have felt guilty about it because Jim is his friend no matter what the law says.
Huck doesn't turn Jim in because Jim in Huck's first TRUE friend. Jim is also the only "family" Huck has ever had that cares so much about him and will protect him.
Huck feels trembly and feverish at the thought of Jim's freedom because he has been taught all his life that helping a runaway slave like Jim is sinful and wrong, so he is conflicted about going against this belief. Additionally, Huck has developed a strong bond with Jim during their journey, and the idea of losing his companion makes him anxious and unsettled.
Jim feels that Soloman is a fool. Jim thinks that Soloman has a lot of kids, therefore when Soloman offered to cut the baby in half in the story of the two mothers, Jim thought Solomon actually wanted to kill the baby and just didn't care. Huck tries to reason with Jim that Solomon had his reason and didn't really want to kill the baby, but Jim was stubborn and insisted that Soloman wasn't a wise king, but a fool.
He told Huck that Jim had been sold as a runaway slave!!!
Jim is betrayed by Huck, the duke and king; senseless, Jim thought the two rapscallions are really the duke and the king.
