Jason and Sam Morgan (commonly known by their portmanteau "JaSam") are fictional characters and a supercouple from the ABC daytime drama, General Hospital. They are known to be one of daytime's most popular supercouples. Jason is portrayed by actor Steve Burton; formerly, the role was played by Billy Miller. On December 1, 2017, Miller's character was revealed to be Jason's identical twin brother, Andrew Cain, conditioned to believe he was Jason and assume Jason's identity. Sam is portrayed by Kelly Monaco. First meeting in 2003, their relationship was described as "an uneasy alliance that first blossomed into a friendship." A romantic relationship evolved from that friendship and the couple was involved for over a decade, with General Hospital writers scripting them as soulmates. Together, Jason and Sam have been titled "one of the most romantic duos in daytime," and their relationship has been described as "one of General Hospital's most intimate unions."
