WandaVision has so much to uncover with all the hidden clues in each episode. With no clear identification as to who the villain might be, there are hints that some of the Westview people play a much larger role than being townspeople and this brews more theories for the series.
There is Dottie, the town matriarch. Agnes described her as the "Queen cul-de-sac" and the "key to everything in town." Introduced in the second episode, Dottie and a group of "merry homemakers" prepare for the town's talent show: a fundraiser for the children.
Dottie exhibits the vibes of a woman who's in control, who loves being in control. This is shown when Wanda joined the meeting with her and every woman present seems either scared to move or act on their own or just plainly worships Dottie.
When Wanda and Geraldine talked as Dottie did, she becomes enraged and annoyed. Dottie instructs them when to laugh, when to clap, and when to stop.
This leads to theories that Dottie may be more than what meets the eye – Dottie might not be just another member of the community; she may be playing a role much larger than being the town matriarch.
Is Dottie Mephisto?
To start, who exactly is Mephisto?
Mephisto is a powerful entity in Marvel Comics who reign the dominion of Hell. He can manipulate memories, alter time, and project illusions, something like what is happening to Westview.
In the comics, he turned the whole life of Scarlet Witch upside down when he took Tommy and Billy, Wanda's twin children whom Wanda accidentally brought into life with the fragments of Mephisto's soul. Scarlet Witch was not able to bear the loss of her children that she spiraled down to madness.
If WandaVision is going for this arc of Scarlet Witch, then Mephisto must be the villain. As Mephisto can change his appearance depending on his agenda, he can be hiding in plain sight. This leads to the theory that Dottie maybe Mephisto.
In the fundraiser meeting Wanda and Agnes attended, Dottie scolded a member for not coordinating the chairs to be used for the talent show. Agnes whispered to Wanda "the devil is in the details." Agnes added that "that's not the only place he is," which brings in the question, is the devil just around the corner?
With Agnes being rumored as Agatha Harkness, an ancient enchantress who wiped the memory of Scarlet Witch of the loss of her children, Agatha's connection to Wanda in the series could also hint that Dottie maybe Mephisto.
Agnes has been a nosy neighbor who consistently involves herself with Wanda. If the rumors prove to be true, then Agnes who is hinted to be aware of what is happening to Westview in episode three may be leading Wanda to Mephisto just like in the comics.
With Mephisto as the villain for the first installment of the fourth phase of the MCU, this could lead straight into Doctor Strange in the Multiverse of Madness as Mephisto can break the fabrics of reality and introduce the multiverse.
If Dottie isn't Mephisto, is Dottie Arcanna Jones?
Another theory as to who may Dottie be is that she may be Arcanna Jones.
With the recent release of the trailer for Marvel's Heroes Reborn, the Supreme Squadron takes the place of being Earth's heroes as it is set to be an Avengers-less universe and Arcanna Jones is a member of that team who possesses the magic to control natural forces and alter light making it possible for her to create illusions.
As shown in episode three of WandaVision, Dottie is the wife of Vision's friend, Phil Jones, a character who bears the same name in the comics as Philip Jones, the husband of Arcanna Jones. If this is the arc that MCU would follow, Dottie's leadership in town may be a reference to her being a Supreme, the head witch.
This theory could lead to the speculation that Westview is a place for witches to avoid what happened in the Salem trials.
The Salem trials have been teased by Agnes in the first episode where she shared to Wanda that her anniversary with her husband is June 2nd, exactly the date when the Salem trials began.
If Dottie is Arcanna, it could also lead that the multiverse has already entered the MCU as human-inhabited multiverse are now leading into each other.
As WandaVision continues to reveal more of what is happening to Westview and brew more theories into the strangeness of the town like the ominous beekeeper or the mysterious red chopper, Dottie is definitely someone to look out for, whether or not she may be a friend or a foe.
WandaVision returns on Friday, January 29, 2021, on Disney+.
