Wanda embarks on a troubling journey revisiting her past for insight into her present and future.
In 1693 Salem, Agatha Harkness is set to be executed by her mother and her coven for practicing dark witchcraft. But as they attempt to drain her life force, she reverses the effect and kills them all before fleeing. Back in the present day, Wanda Maximoff attacks Harkness, but finds her magic nullified by the presence of protection runes cast in the basement. Harkness taunts her for convincing herself that the impostor Pietro was her real deceased brother in her grief, allowing the witch to get closer to her. She also reveals her fascination with the Westview Anomaly Maximoff had created, which involves simultaneous mass usage of mind control and transmutation over an expansive radius.
Wanting to learn the origin of Maximoff's incredible magical abilities, Harkness opens a door to the past; 1999 Sokovia, when the Maximoff family gather to watch Wanda's favorite sitcom, The Dick Van Dyke Show. The idyllic suburban life featured in the show was what she enjoyed in contrast to the violence of a war occurring outside. But in the middle of their binge, the Maximoff parents are killed when their house is bombed by weapons made by Stark Industries. One Stark bomb lands in front of Wanda and Pietro, which appears to be defective when it fails to explode after two days. Harkness suggests Wanda had used her latent magic to cast a probability hex and neutralize the weapon.
Their next stop is at a facility where HYDRA was experimenting on various test subjects with the Mind Stone, usually with lethal results. But when the young Maximoff volunteers to enter the test chamber, the Mind Stone is drawn to her presence and explodes. In the blast, she sees an apparition of herself as a mythical being before collapsing; security footage is spliced to omit the explosion. Maximoff became the experiment's first survivor, and the Mind Stone's power amplified her abilities. Then, Harkness and Maximoff visit the Avengers Facility, where the latter and Vision would develop a blossoming romance spawned from their discussions about grief.
Finally, the two view Maximoff's arrival at S.W.O.R.D. Headquarters several days after attending Tony Stark's funeral, wanting to recover Vision's remains for a proper burial. She meets Tyler Hayward, who takes her to the operating room where Vision's corpse is being dismantled by S.W.O.R.D. personnel, much to her horror. Hayward also disallows her from retrieving the remains due to the valuation of Vision's vibranium body, leading Maximoff to break into the operating room and attempt to interact with her deceased lover. However, she is unable to feel him there, leading her to leave the facility without further incident. Driving to an empty lot purchased by her and Vision in Westview, Maximoff is overwhelmed with grief as she collapses to the ground in anguish, inadvertently unleashing a colossal amount of magic that manifests the house.
Maximoff then releases a second wave of magic, which transforms Westview into a sitcom suburb, form a barrier to isolate the town from the world, and create a new Vision out of thin air. As Maximoff sees herself settling with her Vision in her idyllic paradise, she also finds herself in a studio with Harkness in the audience, who applauds her before vanishing. Soon, Maximoff hears the cries of her children Billy and Tommy outside and discovers that Harkness had taken them hostage. Having deduced Maximoff's abilities as a manifestation of Chaos Magic, Harkness scolds her for using her powers for mundane purposes and informs her that she is the mythical Scarlet Witch.

- The title of the episode is in reference to the statement said in recap sections of show, like "Previously on WandaVision".
- During the flashback to the day Wanda Maximoff and Pietro Maximoff lost their parents, one of the DVDs Oleg had in his case was Malcolm in the Middle. But the flashback takes place in 1999, and Malcolm in the Middle did not start airing until January 9, 2000, so the series would not have been out on DVD yet.
- The episode retcons Avengers: Age of Ultron's description of the Novi Grad Bombings. According to the film, the Maximoffs were having dinner when the first shell hit making a hole on the floor, and that the whole building started coming apart; their parents died going into the hole for a failed rescue effort. In the episode, they were watching sitcoms when the first shell hit the ceiling and the twins' parents were buried under the rubble, dying instantly.
- The scene of Wanda coming across the disassembled remnants of Vision's body in the S.W.O.R.D. lab is taken from West Coast Avengers #43 into #44.
- In addition, the scene of Vision being dissected with his body stretched out across multiple tables is a direct nod to a panel from those comics.
- Vision being reactivated in a pure white body seen in the mid-credits scene is in reference to the comics, where Vision had a white form upon being resurrected.
