WARNING: The following contains spoilers for WandaVision Episode 4, "We Interrupt This Program," now streaming on Disney+.
It became clear early on in WandaVision that the government agency known as S.W.O.R.D. would play a key role in the series' events, but the nature and history of the organization remained a mystery -- until now. In Episode 4's "We Interrupt This Program" and its dramatic shift in narrative perspective, the rampant theories of many fans were laid to rest as we learned a little about S.W.O.R.D.'s history, its purpose and its founder. In fact, its founding may be the most startling discovery of all.
The episode shifts outside of the saccharine unreality of Wanda's world and grounds itself in the perspective, first and foremost, of Monica Rambeau as she recovers after returning from the Snap during the events of Avengers: Endgame. Coming back to life at the same moment as half the universe's population, Monica finds herself in a hospital where she believes she nodded off for a moment as she waited for her mother to recover from a successful surgery. To her horror, she discovers she has been gone for five years and that her mother died from cancer in the interim.
Her mother was not an unknown individual, either, but a recognizable name with a supporting role in Captain Marvel: Maria Rambeau. In that film, Maria is a pilot alongside Carol Danvers and assists the heroine in the film's climax. At the time, Monica was still a child and she seemed inspired by Carol, and the heroine's words echo in her memory even as she recovers from the Snap in WandaVision. The show further reveals that Maria took a central role in extraterrestrial affairs following Captain Marvel. In fact, she's the one who founded S.W.O.R.D.
Unlike the first three WandaVision episodes, which featured characters created specifically for the show, the most recent episode knits the series into the rest of the MCU by establishing connections through S.W.O.R.D. Not only was Maria its first director, but Monica's assignment to investigate Westview draws in FBI Agent Woo from Ant-Man as well as astrophysicist Darcy Lewis from Thor. In many ways S.W.O.R.D. seems to have taken the place of S.H.I.E.L.D., a space left vacant since its collapse in Captain America: Winter Soldier, though the new agency's ultimate goals are not as clear.
It's revealed that the acronym S.W.O.R.D. stands for Sentient Weapon Observation and Response Division, yet its role seems to have changed between Maria's founding of the organization and WandaVision. The new Acting Director Tyler Hayward is friendly with Monica even as she puzzles over the changes to the organization since her mother's death and her own absence. From everything we know about Monica thus far, she seems to be shaping up to be every bit the hero her mother was.
Those familiar with the comics are well aware that the passing glimpse of Monica's nickname "Photon" in S.W.O.R.D. headquarters has a greater significance, as she takes up the name -- along with the title "Captain Marvel" at one point -- during her career as a superhero. With the power to convert her body into light energy for an array of effects, she is a formidable force in the pages of the comics, but the character has a ways to go in the MCU before she develops such fantastical powers.
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.
