New experiences make Caleb a changed individual. If he doesn’t survive in this one then everything which he worked for in the past will get destroyed in front of his eyes and all he would be able to do will be to watch till the world comes to an end. Jeffrey Kafer has not taken any kind of break in the narration. No signs of tiredness are shown by the narrator because he has shown a complete interest in the development of the plot.
The Sheriff and Weapons of War were also blessed with great voices which garnished every chapter and episode of those series. Having a good voice for the show helps things in more than one way. A good narrator helps to depict the emotions in the story clearly and also makes the story better understandable.
