Jealousy is a personification of forces external to the woman courted by the narrator. This character is not described physically, but it is clear that Bialacoil is even more afraid of Jealousy than of Daunger. It is after Jealousy appears, wakened by Wikked-Tonge, that Drede appears. This character commands the tower to be built to imprison Bialacoil and the roses and appoints the guardians around and within it.
