Sally Jackson is the mother of Percy Jackson. At one point, Sally entered a relationship with Poseidon, and the two had a son, Percy. When Percy was seven months old, Poseidon was forced to leave after Zeus decreed that the gods could not interact with their demigod children. At one point, Sally married the abusive and lazy Gabe Ugliano as he masked Percy's natural demigod odor, putting up with years of abuse for her son’s safety.
