Father Dougal McGuire Linehan and Mathews to discard the mockumentary format and expand the Father Ted episode to a traditional sitcom, Father Dougal became one of the main characters. When writing Dougal, Linehan and Mathews drew on Stan Laurel, incorporating some of Linehan's own behaviour during moments of confusion. Linehan and Mathews saw O'Hanlon in a modernised Shakespeare play broadcast by RTÉ, and were impressed by the "weird, gormless" face he could pull. Linehan later said, "That was Dougal right there. He was just spot-on and he became our secret weapon. The show took off so quickly because Ardal was so instantly funny."
Father Ted Crilly transferred to an idyllic parish in Castlelawn, Dublin, but is soon sent back to Craggy Island when irregularities are discovered in his expenses. In the final episode, "Going to America", Ted persuades the suicidal Father Kevin not to jump off a ledge at the "It's Great Being a Priest! '98" conference. Impressed, an American priest offers Ted a place at his Los Angeles parish. Ted, unable to tell the others that they cannot come with him, is wracked with guilt; he cancels the move at the last minute, then tells them that he has realized he belongs on Craggy Island.
