Gerald and Rachel's marriage came under strain as Rachel spent more and more time with Jack and Henry Foss, eventually entering into an emotional affair with Henry. Jealousy got the better of Gerald and he attempted to murder Henry by drugging and releasing Jack prior to a planned feeding by Henry. His plan came undone when Rachel instead came to feed Jack and was infected by Jack's deadly spores.
Gerald confronted Henry in the medical centre over the affair and stabbed Henry. Believing that Rachel's death was inevitable Gerald wished to die and tried to force Henry to change into a werewolf to save his own life and kill him, as well as punish Henry who would have to live with the guilt of the deaths of Rachel and himself. He was stopped by Bigfoot after been distracted by Rachel suffering a seizure.
