Jason was the father of Melissa and the former husband of Sandra. He and Sandra were divorced by the time Melissa was eleven.

Because Melissa's birthday was on Christmas Day, it was a tradition in their family to celebrate it on 25 June, Melissa's half birthday. This tradition continued after the divorce, and it was the only time Melissa ever saw them together. When Melissa was eleven-and-a-half, the three went to WendiWorld. Jason and Sandra constantly argued over Sandra's boyfriend, upsetting Melissa so much that she unknowingly allowed herself to be controlled by an alien sprite that had been abandoned on Earth centuries ago. After their harrowing experience, Jason and Sandra parted more civilly when Sandra took Melissa home. (PROSE: Spookasem)
