What kind of person is Kay? Explain. (character)

Kay is Wart's foster brother and is not nearly as nice of a young man. He is peevish, spoilt and manipulative and attempts to take credit for pulling the sword out of the stone, but fortunately this pretense is discovered and the country is saved from a Kay-led monarchy. Although his heart is basically good his character is nasty and filled with jealousy. At first we quite like him because he is a good sport about sharing the glory on his adventure with Robin Hood. He is also skilled with a bow and arrow and saves the group from the fearsome Griffin with one shot. Gradually, though, he becomes insufferable and the petulant and temperamental side of his personality overshadows his better traits.
