What happens to Huck? What’s wrong with him? Where does he end up? Who takes care of him? Compare Huck’s experience to the experience of the children at the picnic.

It is difficult to say which chapter you mean but I think you are referring to chapter 29. Huck realizes at that moment that Injun Joe's dangerous "revenge" job is to seek harm on the Widow Douglas. Injun Joe proceeds to describe to the Spaniard how the widow's late husband had ordered him to be horsewhipped "like a nigger" in front of the jail a long time ago; as revenge, Joe intends on "slit[ting] her nostrils" and "notch[ing] her ears like a sow!"

You need to submit each of your other questions one at a time. Thanks!
