Spoiler: America's once-massive population of buffalo is eventually destroyed by the rise of railroads and industrialization, as well as by wasteful, out-of-control hunting by the white frontiersmen. Ouch. Because we know things like this (y'know, being in the future and all), these seemingly small details end up taking on massive importance.

When Glass decides to take on a pack of wolves, we were pretty sure that the dude had gone bananas. He should know more than anyone how quickly a wild animal can make mincemeat out of us fleshy humans, right? Even after he walks away victorious, we don't know whether to commend him for his bravery or slap him for his stupidity.

Glass's rumble with the wolves displays both his strength and ingenuity. First, it shows his ingenuity because he's able to craft a weapon using only gunpowder and sage, showing his skills as a proto-MacGyver. But it also shows his strength because, well, it takes some serious chutzpah to go face-to-face with one of nature's most feared predators.
