The setting has changed because they are on the road and running away from something. The boy believes more in staying alive and being the good guys. The man(the father) is changing because he is deciding if he should abandon his son or not. This book is reminding me of the hunger games with the setting and how they are running from death. Compared to today this book has some simiularities with starvation, For example Africa and Pompeii with the ash and destruction.
