 " Peter 's got his own issues to deal with , and Caspian 's got his own issues to deal with , and when neither is willing to compromise , there 's bound to be friction . Peter came back to Narnia expecting to be king again and that everyone would do as he said , and Caspian is unwilling to let him take over , so that causes some of it . That 's really what happens . And it 's a lot about humility . I think they both have to learn a certain humility [ ... ] and that 's really what a great king needs is to be humble , to listen to his people , to be willing to compromise , and they start off as these sort of angry teenagers , and become kings at the end .
