What happens to Huck while Tom and Becky are gone?

Jim: just as he was about to be executed, the townspeople realize that Miss Watson freed him (in her will) when she died 2 months earlier.

Huck: the dead man found on the island earlier in the book was Huck's father; he takes his money and goes on adventures out west.

Tom: his leg was shot, so that eventually recovers; he then settles down eventually.
