Jason first appeared in 1999, on his cousin Paddy's doorstep after his parents had thrown him out after he had told them he was gay. Paddy had told Jason to keep this a secret as Paddy's then-in-laws, the Dingles, wouldn't take it well.
Jason discovers a woman in labor at the side of the road, and has to help her as the ambulance wouldn't arrive in time. With some help with the 999 operator, Jason helps Latisha give birth to a healthy boy she names Kirk, as a thank you to Jason. When Latisha arrives in the village, everyone is surprised that Jason managed to help with a birth.
Jason left for Portugal on 31 January 2002, but he came back briefly in December 2002 to offer Latisha and her family jobs. Latisha, her mother Cynthia and Kirk, moved to Portugal with Jason.
