SWORD will make it's MCU debut in WandaVision, and it's rumored they will reveal the existence of Mutants to the audience, and to Wanda.
Also I could be wrong but I think the live-action rights to SWORD, and Harkness was owned by Fox until Disney bought Fox, and the rights went back to Marvel which if true then it's interesting that Feige used stuff for the WandaVision show that Fox used to have the rights to.
Shoot it's even more interesting that now in the comics seems Magneto is in SWORD, there's this plot with Wiccan, Magneto may have to see Wanda, and with Feige over the comics it makes me wonder if this like a mandate by him to match with WandaVision?
I mean WandaVision has SWORD, Wiccan, and Speed, and it's rumored Wanda will find out about Mutants, she's a Mutant/Magneto's Daughter, and what happened to him.
Which with that rumor it makes me wonder if they're gonna pull a twist, and reveal their Parents they mentioned in Ultron was actually Magneto/Magda, and instead of their Dad being killed he was actually captured by Hydra who could've sent the Stark missile to bomb their house, and capture Magneto.
If they do then they could also reveal the Twins had a Sister name Ayna that died by the missile which could be a nod to her dying in the comics.
I don't know I just feel like this could be a way to tied it all together without it feeling like a mess so to speak.
