My theory about Sylvie in Doctor Strange in the Multiverse of Madness. As the story goes, Dormammu should have already returned after the time stone was removed from Earth, Mordo has been forgotten in the MCU since the first film, as has Cristine Palmer. So why would someone as unimportant to the MCU as Sylvie be in the movie? In addition to the double stun additions by actors Sophia Di Martino, Tom Hiddleston and Owen Wilson in the film that will face the Multiverse. There is a coherence that doesn't involve what you're thinking. Actress Sophia Di Martino has said in several interviews that Sylvie was inspired by Sylvie Lushton, but with a different origin, and in addition to Assemble de Loki the producers confirmed that she is Sylvie Lushton, who used the name. Sorceress awakening Amora's rage, who exiled her from the 10 realms for it. Let's go to History, maybe Loki comes out of that TVA where nobody knows him and it has already been confirmed that he belongs to another timeline that I imagine to be the canonical one. Since he knows what happened and Mobius maybe knows how to help correct it, it's a consistent help. But what about Sylvie? Perhaps at the end of the movie, they reach the void and she is on the throne of the Kang variant opening all the branches that have already been pruned so she could be killed by Strange and Clea like Easter eggs in Comics or Wanda Killer her . After seeing her use Loki's feelings to push him in a portal and proceed with her revenge, after forbidding him to accept the throne of the Kang variant, perhaps she herself had wanted this from the start and only pretended to be disappointed with Loki, after see that he wanna this throne seeing this, Sylvie used his feelings for her and took that throne for herself, and then I see the relevance of her appearing in Doctor Strange 2 just like the variant Kang appeared in Loki, as responsible for the chaos, and as each character conquers its original title that was distorted in the series, Sylvie Lushton is a villain and not a heroine, she did not fight of her own will, but for revenge. This variant of Kang is the Immortus who is an anti-hero, for the greater good he sacrificed lives, that's how anti-heroes act. And Loki understood him because he is also an anti-hero. But that's just speculation, we'll see what happens next year.
