Even though nearly 300 years have passed in the sprawling science fiction series Foundation, several characters have figured out how to stick around for all three seasons. For the Emperors named Cleon, Brother Dawn (Cassian Bilton), Brother Day (Lee Pace), and Brother Dusk (Terrence Mann), it’s all about showing up as a clone of themselves over the centuries. For Gaal Dornick (Lou Llobell) and Hari Seldon (Jared Harris), they glide through the centuries thanks to cryo-sleep, or by becoming an immortal AI.
But the most tragic and compelling character who keeps reappearing is likely the robot known as Demerzel (Laura Birn). She’s been running the Cleon dynasty for several centuries now, but her existence predates the clone emperors. And now, in Foundation Season 3, Episode 3, Demerzel’s back story gets a very big twist, which puts the pre-Foundation timeline in a new light. Spoilers ahead.
