When dealing with time-travel and an infinite multiverse the end often comes back around to the beginning. The Loki Season 2 finale is that kind of ouroboros, particularly because it's title, "Glorious Purpose," is also the name of the series' first episode. That's not the only thing that makes this episode feel more like a series finale than just a season-ender. The story isn't over for these characters, but they likely won't be told in a show name "Loki." The final chapter in the story shares a quality with the film Groundhog's Day, in that it depicts a near-unfathomable amount of time.
