Jayne: Reavers ain't men.
Book: Of course they are. Too long removed from civilization, of course, but men. And, I believe there is a power greater than men, a power that heals.
Mal: Reavers might take issue with that philosophy. If they had a philosophy. If they weren't too busy gnawing on your insides. Jayne's right, Reavers ain't men. Or they forgot how to be. Now they're just nothing. They got out to the edge of the galaxy, to the edge of the galaxy, to that place of nothing, and that's what they became.
