The following contains spoilers for the third episode of Marvel's WandaVision on Disney Plus.
The third episode of Disney Plus' WandaVision brings more references, hints, Easter eggs, and general insight into what is happening. In this episode, Wanda and Vision are still living inside a sitcom world, this time in technicolor and emulating the look of sitcoms such as The Brady Bunch. Wanda is suddenly pregnant, as seen at the end of the second episode, and she and Vision comedically deal with the unexpected occurrence.
This episode of WandaVision has more clues than ever before as to the nature of the sitcom world and why and how Wanda and Vision are there. There are so many references and hints that it is sometimes hard to tell what could be a fun Easter Egg and what could be major foreshadowing. Every hint and reference seems to have meaning in WandaVision.
Wanda and Vision's House Number
As in the first two episodes, the house number on the Vision family home is 2800. In 2015, a series of Vision comics ran where Vision builds a synthetic family to live with him in the suburbs because he wants to feel human and normal. While this isn't the exact plot of WandaVision, the concept of Vision trying to live a life with a so-called normal family is seen in both works. In that Vision comic series, the Vision family's house number is 616, representing Earth-616, the universe in which most of the Marvel comic storylines take place. The house number being 2800 in WandaVision could be an indication that this sitcom world is another universe or dimension.
Simser
When Wanda is painting the baby's nursery, the name on the paint cans she is using reads "Simser." Simser could be a nod to WandaVision's storyboard artist, Jeremy Simser. While a cute acknowledgment in itself, there could be more to this reference than meets the eye. Jeremy Simser is also the storyboard artist on Marvel's upcoming film Doctor Strange in the Multiverse of Madness.
WandaVision has been confirmed to be the set up for this Doctor Strange sequel, and Scarlet Witch has already been confirmed as part of the cast. It's possible that the sitcom world of Westview that Wanda and Vision are in is part of the multiverse. WandaVision setting up Doctor Strange in the Multiverse of Madness could also suggest that SWORD will be a major presence in the next Marvel phase.
Wanda and Vision's Twins
When Wanda finds herself suddenly pregnant, with the baby coming "about nine months too early" according to Vision, her and Vision debate about what to name the baby. Wanda likes the name Tommy, calling it a normal All-American name. Vision prefers the name Billy, as a reference to William Shakespeare. Vision even quotes Shakespeare by saying "All the world's a stage, all the men and women merely players," which can also be seen as a reference to him, Wanda, and their neighbors playing the role of classic sitcom characters in this universe. When Wanda ends up giving birth to twins, it looks like both her and Vision will get their way when it comes to names. The twins may have been sneakily foreshadowed earlier in the episode, when Jones is reading a newspaper with the headline "Two Fire Hydrants Added on Main."
Billy and Tommy aren't just regular names, however, they are the names of Wanda and Vision's twins in the Marvel comics. Billy and Tommy end up becoming major players in the Young Avengers comic series. Billy is Wiccan, capable of flight, lightning-based spells, illusions, forcefields, telekinetic abilities, and more. Tommy is Speed, who has superhuman speed and agility, similar to his uncle Quicksilver. Whether Billy and Tommy will exist only in this sitcom universe or if this indicates these Young Avengers will become part of the MCU remains to be seen.
Hydra Soak
The third episode of WandaVision includes a fake commercial mid-episode, just as the first two episodes did. This episode's commercial is for Hydra Soak Luxury Bath Powder, with the commercial narration saying, "Escape to a world all your own, where your problems just float away. When you want to get away but don't want to go anywhere." The narration is yet another indication of Wanda and Vision being in another world, with hints that this world is somehow Wanda's doing. Wanda is shown "rewinding" and controlling the action at the end of episode two and the middle of episode three, and she also ejects Geraldine from the universe at the end of episode three. The audience doesn't know if this world was of her own choice, or if she is being controlled.
Of course, HYDRA is the organization bent on world domination in the MCU. This is the second commercial to reference HYDRA, as the watches in the second episode share a name with HYDRA villain Baron von Strucker and feature the HYDRA logo. It's unclear whether HYDRA has a major part in what's going on or if the name HYDRA, along with Stark in episode one's commercial, is simply hinting that the sitcom reality was made by someone from Earth-616.
The Aspect Ratio
At the end of episode three, Wanda ejects Geraldine from the sitcom world. As Geraldine tumbles down from a portal in the sky onto the ground, the aspect ratio shifts from 3:4, as would have been seen in classic sitcoms, to 16:9, the more contemporary ratio. She falls down in a field in front of a sign that reads "Welcome to Westview," but this is obviously not the Westview that Wanda and Vision are in. This aspect ratio shift is a clever way to make it clear that this is the main world of the MCU, and wherever Wanda and Vision are is not.
WandaVision is available on Disney Plus.
