In Chapter 15, shortly after the incident where Huck and Jim encounter a trio of murderous thieves on a wrecked steamboat, a thick fog sets in at night. Huck gets in the canoe and paddles off to find a place to secure the raft, but he forgets to tie the rope to the raft and accidentally gets separated from Jim. When Huck eventually finds his way back to the raft, he wakes Jim up and tries to convince him that he dreamed the entire episode, fog and all. Jim falls for Huck’s trick for a short while, before piecing the truth back together. But when he figures out Huck’s ruse, Jim shows no sign of amusement. Instead, he explains how deeply anxious he felt at the thought of losing Huck: “When I got all wore out wid work, en wid de callin’ for you, en went to sleep, my heart wuz mos’ broke bekase you wuz los’, en I didn’ k’yer no mo’ what become er me en de raf’.” Huck deeply regrets the trick, and despite his reservations about humbling himself before a black man, he apologizes to Jim.
