Stewart is the inbred father of Pete and husband of Betty. Stewart and Betty have made an agreement with the Tin Man that they will unlock the basement door and let him into the house when the time is right. Stewart seems to be especially created to torment Randy. Stewart reminds Randy of Randy's father who used to beat and torment him. Stewart is "killed" when Randy allows him to drown in a drainage shaft. Stewart comes back to life though to continue to help the Tin Man in his game.
