In Book One, Stanley valued Jack only as a foolamancer but could not be bothered to remember his name. When Stanley attempted to flee to Faq he took Jack to aid in his escape. Stanley became irritated when Jack failed to function properly as a foolamancer. For some reason, Jack seems intensely loyal to Stanley, refusing to turn sides when Jillian attacked Stanley.
Following the battle, Stanley seems to value Jack more, possibly because Jack saved his life in the conflict with Jillian and the ten Warlords of Transylvito. Stanley noted that he was "trying to get better about names", presumably as a result of the problems with Jack, and Jack saving his life in that battle. Stanley now attempts to refer to other units by their names and not their function.
