Chapter 1: The Old Sea-dog at the Admiral Benbow
The narrator kicks off the book by telling us that he is being pressed to write about the events surrounding Treasure Island by a Squire Trelawney and a Dr. Livesey. One sentence in and I already have two complaints: first, we now know that these three characters are all going to survive this story, thus robbing us of a lot of potential drama; second, these two educated men are making the commoner boy do all the writing.
Speaking of which, our narrative is being penned by a young man named Jim Hawkins. I assume. Since he's the narrator, he doesn't refer to himself by name this chapter; but the protagonist in Disney's Treasure Planet is named Jim Hawkins, and as that's the only related media I'm familiar with, I'm declaring it to be the most authoritative source on the matter.
Jim Hawkins
Based on how he spies on the incoming ships and pays Jim to alert him if any sailors are about, it's clear the captain is trying to keep a low profile. Naturally, then, he decides to lodge at the emptiest tavern where he doesn't blend in whatsoever, and where he spends his days getting drunk off his ass and yelling at the other patrons for not joining in when he sings shanties. At the very least, he does pay Jim under the table to alert him if any sailors stop in—and especially if he sees a man with only one leg.
One night, Dr. Livesey happens to be hanging around the inn when the captain has a little too much rum and gets into his routine of commanding the atmosphere of the place. At one point he orders silence, but Dr. Livesey keeps on talking, partly because he doesn't know the captain's rules but probably mostly because he has real middle-class white man energy and just doesn't care. When the captain calls out Livesey for his disobedience, the latter goes, I don't know what business you could possibly have with me. All I have to say to you is that you're going to keel over dead if you keep drinking like that. That'll be $200, and I don't take Medicaid.
Furious, the captain then draws a knife on Livesey to threaten him into compliance, but Livesey doesn't bat an eye. He says, sir, you forget that I'm a colonial-era doctor, which means that I also do mathematics, philosophy, biology, botany, phrenology, and—most relevant in this case—local governance. Back off or I'll see you hanged.
This threat sufficiently cows the captain, who keeps a low profile for a few days even after the doctor has left.
