This article contains major spoilers for the season 3 finale of "Foundation."
Is the future set in stone, or can our actions in the present help mitigate an extinction-level catastrophe down the line? That question has remained at the forefront of "Foundation" since its very first episode, when the brilliant mathematician Hari Seldon (Jared Harris) was first put on trial for his predictions about the downfall of the Empire. Once our main protagonist Gaal Dornick (Lou Llobell) began experiencing disturbing premonitions of the sinister Mule early in season 2, that thematic concern only amplified. It appeared we were headed towards a violent confrontation that would decide the fate of the entire human race, which many of us assumed would arrive at the end of the third season.
