In Dexter, the titular main character has a biological son named Harrison, and while he has appeared in every season of the show since season 4 (and most recently in SHOWTIME's 2021 reboot Dexter: New Blood)—Harrison has actually been played by several individuals. At the end of season 4, Harrison’s mother Rita (Julie Benz) was murdered, and he was left to be raised by his serial killer father, while his two half-siblings eventually opted to live with their grandparents. In the original, universally panned Dexter series finale, a slightly older Harrison is left in the care of Dexter's love interest and fellow killer Hannah (Yvonne Strahovski), who raises him in Argentina after Dexter is presumed dead. Over the course of 4 seasons and a reboot there have been a few Harrison Morgan actors, here's a list of every single one that's appeared on the screen.
Viewers have already been introduced to teenage Harrison Morgan (Jack Alcott) in Dexer: New Blood season 1. The character appeared first as a figure dressed in all black who seemed to be following Dexter around Iron Lake, New York where he lives. Dexter confronted Harrison after the boy broke into his home looking for proof that the man was indeed his father. Initially, Dexter lied to Harrison and claimed to have no idea what he was talking about. At the end of the first episode, however, he revealed his true identity and asked Harrison to stay in town. Throughout Dexter: New Blood the new Harrison Morgan actor plays the character with a mixture of cold indifference, teenage angst, and simmering violence lurking beneath the surface. Unfortunately Dexter: New Blood ends with Harrison killing his father, as he realizes that Dexter actually fits Harry's code.
