The Mandalorian, a Star Wars show that introduced new characters, was the only big ticket item in 2019 and 2020
The Falcon and the Winter Soldier and Loki followed that successful series.
After Avengers: Endgame, Tom Hiddleston's Marvel rogue enters the Time Variance Authority, the covert organisation that protects the universe's Sacred Timeline
The TVA's role in this carefully maintained Marvel timeline is to repair any "variances," which is how this variant Loki ends up in the TVA's hands
The introduction of Sylvie Laufeydottir, a Loki variant who has been evading the TVA since she was a young child, is arguably the biggest surprise of Loki season, second only to Jonathan Major's He Who Remains Kang.
The Time-Keepers are revealed to be androids acting as a front for the mysterious He Who Remains, who waits at the Citadel at the End of Time to give Sylvie a choice
Sylvie's decision to kill He Who Remains creates the universe in Spider-Man: No Way Home and Doctor Strange and the Multiverse of Madness and appears to remake reality.
Photos from the set have verified at least one of Loki, Sylvie, and Mobius' new adventures on Disney next year.
Fans noticed that Sylvie's 1976 red uniform as she leaves the fast food business suggests she's trying to settle down before Loki returns.
