Parallel - pg. 259 "He looked up, his wet and grimy face. Yes I am, he said. I am the one."
Very early in the book, the father says the son is the only thing he is living for. This brought up again, except the son says it himself, showing the son is exactly how the man imagined him to be.
Contrast - pg. 259 "The man squatted and looked at him. I'm scared, he said. Do you understand? I'm scared."
For really the first time, the father is taking off this tough persona of his towards his son and expressing how he truly feels. Earlier throughout the book he constantly urges his son to keep going, when he himself has doubts of their survival and sometimes just wants it all to end. This is a contrast to that and instead he is finally honest with his son.
1. Does the son think his dad was lying about being the "good guys", based on what he says on the top of pg. 268?
2. Does the father die of an illness other than his infected wound, as on pg. 272, McCarthy writes, "He spat into the road a bloody phlegm." I would assume a serious leg injury, even if infected, would not cause you to cough up bloody phlegm, so does he have some kind of other problems?
