WARNING: The following contains spoilers for Marvel's WandaVision Episode 3, "Now in Color," now streaming on Disney+.
Keen-eyed viewers were quick to catch references to S.W.O.R.D. in the debut episodes of WandaVision, and as the series unfolds, it's clear the organization is of central importance to the plot. Much about Wanda's life in the eerie sitcom reality comes as a mystery, but the more that S.W.O.R.D. ties into it, the more Wanda's relationship with the government operation grows in significance. In fact, she could have been an agent for S.W.O.R.D. before the series began.
It's clear from the start that nothing is as it seems in Westview, the formerly black-and-white suburb inhabited by Wanda and Vision. Characters pass through moments of confusion and lucidity, reality shifts from one moment to the next and a government operation monitors the events from a space beyond Westview. Judging by the logos seen intermittently on monitoring desks, the beekeeper's suit and Geraldine's necklace, that operation is S.W.O.R.D.
Introduced as an analogue to S.H.I.E.L.D. that primarily deals with extraterrestrial affairs, the organization is a natural fit to introduce to the Marvel Cinematic Universe following the events of Infinity War and Endgame. With S.H.I.E.L.D. in disarray and Earth's engagement with the rest of the universe following the Snap more critical, it's sensible that S.W.O.R.D. would step up to take charge of the world's safety. In order to do so, they would need recruits, and Wanda is a natural fit.
Only briefly seen following her resurrection from the Snap in Endgame, Wanda sought vengeance on Thanos for killing Vision. Having found it, joining S.W.O.R.D. as a super powered asset in protecting Earth from similar extraterrestrial threats would be a natural next step. If Wanda has a history with S.W.O.R.D., that would explain the oddly tender approach the organization takes to monitoring her.
Geraldine almost seems like a familiar friend until Wanda banishes her from Westview, and the voice on the radio pleading with Wanda seems genuinely concerned for her safety. She also seems to know the threat S.W.O.R.D. could pose, recognizing their logo and subsequently attempting to remove anything tied to them from her and Vision's life. If she was a former agent, this could explain her powerful reactions to seeing the logo throughout the series.
The explanation would give a unique twist on the character as she isn't associated with the organization in the comics. At the same time, it works perfectly in the context of the MCU in terms of fitting disparate pieces of the universe together in an oddly compelling way. Nothing in WandaVision is as it seems, but it appears the Scarlet Witch's relationship with S.W.O.R.D. runs far deeper than expected.
Written by Jac Schaeffer and directed by Matt Shakman, WandaVision stars Elizabeth Olsen as Wanda Maximoff/Scarlet Witch, Paul Bettany as Vision, Randall Park as Agent Jimmy Woo, Kat Dennings as Darcy Lewis, Teyonah Parris as Monica Rambeau, and Kathryn Hahn as Agnes.
