Marlow goes to sleep, but wakes suddenly just after midnight. As he looks around he notices Kurtz has disappeared. On the bank of the river, Marlow finds a trail through the grass and realizes Kurtz must be crawling. He catches up to Kurtz just before he reaches the native camp. Marlow realizes that though he's stronger than Kurtz, all Kurtz has to do is call out and the natives will attack. Kurtz, realizing the same thing, tells him to hide. Marlow says, "You will be lost, utterly lost." Kurtz pauses, struggling with himself. Marlow watches him, and realizes that Kurtz is perfectly sane in his mind, but his soul is mad. Kurtz's soul, Marlow says, "knew no restraint, no faith, and no fear." Yet in the end Kurtz allows Marlow to support him back to the ship.
