Butler rammed a forearm toward the bridge of Remo's nose but the arm struck only air and then Willie Butler felt a biting pain in his chest that turned to fire and the fire was flashing red and pure and it burned worse than all the fires he'd ever seen and in that last flash of flame, he thought back, and his mind said, it's me, Sis, it's Billie, I really can run fast because I know it, and someday I'm gonna be a big man and his sister was saying no tomming swamp nigger ever gonna amount to anything, but Sis, you were wrong, I was wrong, hate and violence isn't the way, it just doesn't work, but his sister didn't answer and suddenly Willie Butler didn't care anymore because he was dead.
