News of Original Sin casting comes two years since the conclusion of limited series Dexter: New Blood, a sequel which saw the Bay Harbour Butcher killed by his own son Harrison.
Showrunner Clyde Phillips explained to Rotten Tomatoes of this shocking twist at the time: "We needed him to [die], I think. Dexter is an antihero, which is [still] a hero that we like, but he is still psychotic. And he kills people, and you're not supposed to kill people.
"So it's, in a way, it's just desserts. In a way, it's what has to happen. And as for the specifics of the method of how it happened, that evolved in the writing room. We had great writers, and it's what we call 'best idea wins.'"
Dexter: Original Sin will air on Showtime in the US and Paramount+ in the UK. Dexter and Dexter: New Blood are both available to stream on NOW.
