In a novel filled with firefights, bear attacks, and high-speed boat getaways (okay, that last one is a stretch), it's the quiet moments that hit us the hardest. Pig had been a back-up character for most of the story, a bit of comic relief, and we don't get this tiny glimpse into his life until he's already dead. Oof—now that's a bummer.

A what? As it turns out, a bullboat is a type of craft traditionally made by the Pawnee that's made out of processed buffalo hides. You learn something new every day. Good thing Glass had a positive enough relationship with the Pawnee to learn things like this from them.

While we've talked about Glass's determination in positive terms for the most part, the truth is that it's rooted in a very dark desire: revenge. Would Glass still have been so driven to survive if he hadn't been betrayed by Fitzgerald and Bridger? We're not so sure.
