He was first mentioned as working with or for Bucky O'Neill in "Hoofin' It". Damian also dated Nature Kate, as revealed in "Nature Clarence". In "Pizza Hero", he appears on a picture (that was taken in 1998), and was presumably Ms. Baker's ex-boyfriend. He finally appears in "Rock Show" as it shows he's given up being a ladies' man and became a priest.
