All the Pretty Ponies Second

I feel that the novel is finally starting to take off and becoming and interesting western story. As always , McCarthy is a master at painting the picture of perfect imagery whether it be a western setting or an apocalyptic America setting. I have recently started to enjoy comic relief that the characters have started to provide. I guess I didn't expect much since "The Road" did not have any comic relief whatsoever. I am happy that McCarthy decided to include this because otherwise I feel like I would be pretty bored with this novel. A few questions I have is what roles exactly do each character play in the novel and has John appeared to be a Christ figure so far?
