Character Analysis
The captain's name is a nod to Thomas Hobbes, author of the famous political work called… wait for it… Leviathan. It's a nice little Easter egg planted in the book for those who get the joke.
We don't actually see Captain Hobbes too much, but he seems like an okay dude, overall. Like any captain, he's confronted with a lot of tough decisions: he has to decide which two middies to keep on board, what to do after the Leviathan crashes when it comes to letting the beasties die so the men can live, and how far to push the question of Alek's true identity. He takes his responsibility to the ship and to his country very seriously, but he also seems to be kindhearted.
