WARNING: The following contains spoilers for She-Ra and the Princesses of Power Season 3, streaming now on Netflix.
Season 3 of Netflix's She-Ra and the Princesses of Power pushed Etheria's alliance led by Adora to the limit as Hordak continued to wage war on them. Catra opened the portal Hordak and Entrapta were working on throughout the season, which led to the planet getting trapped in a rift in space and time.
To restore the planet and reality, Queen Angella of Bright Moon sacrificed herself by remaining in this dark dimension. However, just before she did so, the show suggested one of the rebellion's major fallen heroes might actually be alive: King Micah, Angella's husband and Glimmer's father.
The first two seasons detailed Angella and Glimmer's fragile relationship, with the queen eventually admitting she was the one who ordered Micah into the battle from which he never returned. Angella felt guilty about her husband's death, and it wore down her relationship with her daughter. The fake reality made everyone's dreams come true, and Angella, Glimmer and Micah were a happy family, ruling Bright Moon.
But as Adora/She-Ra retained her memories and convinced Angella to abandon this false reality, the plan quickly became a mission of sacrifice as the queen would have to ensure the rift remained sealed by staying on the other side. This allowed Adora to lead the rebels back in the real world. But as the hold is broken on Angella, the seemingly Micah is seen begging her to stay, telling her "Wait, I'm not --" just before the illusion cuts off. Fans have begun to speculate this means he isn't dead and the projection was dropping hints as to his true fate.
Seeing as Micah was an expert wizard, we can't put it past Shadow Weaver (his former mentor when she was Light Spinner) to have him imprisoned. Hordak is the kind of person who could have had her siphoning his magic too in a cell as he was her most gifted student. She may have even kept Micah locked up secretly from Hordak, as they had a paternal bond, and Micah did try to save her when her corrupt ways were exposed and she turned into an evil sorceress. This would sync up with the '80s cartoon where Micah was held as a prisoner of the Evil Horde and tortured by Hordak's forces.
Other theories suggest because of his powers, rather than die, he might have been lost in space and time, as well, with his consciousness wanting to keep his family there with him, selfishly, when the illusion was created. These theorists believe he could soon reunite with Angella in this realm, or that Glimmer, She-Ra and their friends may come searching for the queen there and find a trail leading to Micah. Micah learned a lot from Light Spinner, especially regarding how the dark arts could prolong life, so an easy explanation would be he tried to use it to save himself and it backfired, marooning him in this abyss.
Ultimately, the possibility of Micah's return is intriguing, as it might give Glimmer back one parent just as she loses another, still leaving up the possibility for a full reunion. The Etherian alliance on the whole definitely needs some sort of stable figurehead, and whether it's one or both of the royals, it makes Glimmer's life all the more interesting and could provide the happy ending fans want for Bright Moon's throne.
