This guy really is far the hell out. "You ain't heard," he says, "then it don't matter."

It's not this guy's problem, obviously. Wherever they are, wherever they're going, it's with a free and clear outside world. He saw the defenses this place has, and they're not right for fighting off the swarms of the dead that could be lurking in the woods. No, they don't have that problem, here.

Their problem is, as always, the people.
