Ever since it was revealed from a set photo that S.W.O.R.D. would be involved in the plot of WandaVision, fans have been racking their brains on why S.W.O.R.D. would be there in the first place. As of now, it's rumored that the plot of the show, from what has been officially shown, is about Wanda entering or creating a world in which her and Vision are happily married, while also being based on multiple sitcoms over the decades.
However, a recent report from Murphy's Multiverse may shed light on why this new secret organization is involved.
Charles Murphy from Murphy's Multiverse is reporting from two valued sources that one subplot in WandaVision will take inspiration from a story in John Byrne's West Coast Avengers "Vision Quest."
More specifically, it will take inspiration from the story beginning in issue #42, in which Vision goes missing. Wanda searches for him and eventually finds that he was taken, stripped to his metal frame, and had all of his data wiped, leaving him with no memories of Wanda.
Charles describes how his sources explained this will be adapted in the show:
It looks like one of the subplots... centers on Wanda going Humpty Dumpty and trying to reassemble Vision after his parts have been scattered around the world. This is the part where a little context would go a long way but, unfortunately, none exists.
WHAT THIS MEANS
As Charles himself says, it's frustrating not knowing why Vision is seemingly scattered around the world. However, this could be interpreted in two ways: either his parts are scattered around the world or his data is.
This could very well explain why S.W.O.R.D. is involved in the show in that they may have taken Vision's body, but considering that Teyonah Parris is there, who plays Monica Rambeau, with S.W.O.R.D., they might be there to help fix Vision for Wanda instead.
As for why Darcy would be here? It's still baffling why S.W.O.R.D. would want her involved or why Darcy would involve herself. Did she become a bigger deal in the five-year time skip during Avengers: Endgame? Did she move on from political science as a major? Did Jane Foster or Selvig give her a good reference?
Honestly, who knows at this point, but whatever the case, this new piece of news seems to make S.W.O.R.D. setting camp in this series make a whole lot more sense.
