Warning! The following contains spoilers for the Legacies Season 3 finale "Fate's a Bitch, Isn't It?" Read at your own risk!
Legacies has been all over the place in Season 3, and despite all that happened, it seemed the Salvatore School students never got any closer to tracking down Malivore. Little did they know he was right under their noses, as the finale confirmed a popular fan theory that started way back at the beginning of the season. Yes, Malivore was posing as Landon. And that raises one very big question: what happened to Landon?
Legacies made it clear that Malivore was posing as Landon but left fans speculating on the fate of Hope's ex-boyfriend. Luckily, it seems like they'll get some answers on that, as Alaric and the students managed to subdue him (after he stabbed Clarke and devoured Cleo) and put him in chains behind bars in the gymnasium. Answers will come in Season 4, I'm sure, but that doesn't change the fact that I, along with many others, want answers now.
The prevailing theory towards the beginning of Season 3 was that Landon made a deal with his father in the prison world episode and that Malivore took control of Landon and escaped with Hope. I still think that's possibly what happened, though there are some uncomfortable things Legacies would have to address if that were true. For example, if Malivore escaped with Hope, then that means she had sex with him and not Landon. Obviously, that's a scenario no one would like to think about, so hopefully, that wasn't when the switch happened.
I also have to think that while Malivore may have followed Hope to Earth, Legacies has shown fans scenes with the actual Landon. For example, I'm inclined to think that the episode with Landon escaping the Prison World and battling Necromancer was the real Landon. But then, the Landon we've seen recently confessed to being out of the Prison World long before he officially returned. Legacies has a lot of explaining to do, but we're not getting those answers anytime soon.
Another theory I have is that Landon and Malivore are currently one and the same, and that was the deal Landon struck with his father to ensure Hope's escape from the prison world. This would allow Landon to be the character fans still know and love (or love to hate) and Landon to still serve as the big bad for Season 4.
The only other possibility is that Landon has been dead for quite some time, though I highly doubt that's the case. Legacies already did an arc where Hope more or less mourned Landon's death, so if there was a time to confirm that, I would imagine it would've been done there. Confirming Landon's death to open Season 4 would be a weak reveal and not a way to kill off one of the show's more important characters.
We don't know what's happening with Landon or Malivore, but we do know when Legacies fans will get some answers. Legacies returns to The CW Thursday, October 14th at 9:00 p.m. ET.
