Like his sister, he was a very old witch, and was in fact Tracy's younger brother. He posed as a high school art teacher at the school Tracy went to. Sam and Dean visited him to talk about Tracy. Consequently, Don showed them her work. Soon after visiting him, Don placed hex bags in their motel room. Sam and Dean found the hex bag ingredients in Don's desk after figuring out it was him. As Don was performing the ceremony and was about to sacrifice Tracy, Sam and Dean shoot him. That made him the final sacrifice needed to summon Samhain. Samhain used Don's corpse as his vessel.
