Burton reprised the role in 2017. Jason was born offscreen in September 1981 and the character made his onscreen debut weeks later but was seen portrayed by a child actor in November 1981 as the son of Dr. Alan Quartermaine (Stuart Damon) and his mistress, Susan Moore (Gail Ramsey), later adopted by Alan's wife Dr. Monica Quartermaine (Leslie Charleson). As one of the longest-running characters on the show, the role was played by various child actors from 1981 to 1988. In 2014, Billy Miller was cast in the role. With Burton's 2017 return, Miller's casting was later retconned as Jason's twin brother, Andrew Cain.
