"Jack had to think for a moment before he could remember what rescue was"

Jack, Simon, and Ralph are talking about the fear of the beast in the littluns and Jack is the only one who sympathizes with them. He says that when he hunts he feels as if there is something watching him but Ralph and Simon don't understand and they just want be to be rescued. Jack wakes up from this idea as he distracted from all the impulsivity and violence and hunting, he forgets that about being rescued because he is comforted by the idea of a life on the island (page 53)
