WandaVision: 5 Reasons Mephisto Is The Main Villain

5. Dottie's Demon Vibes

Dottie Jones is a new character introduced into the MCU, as a nosy neighbour and queen of the hierarchy of neighbourhood housewives, she could already be viewed as a literal demon.

However, there are multiple signs that Dottie (Emma Caulfield Ford) is in fact either Mephisto in disguise or being controlled by the demon. Dottie's attitude towards the neighbours and Wanda is seen as devilish, however many seemingly throwaway lines add to the theory.

There are numerous hints throughout the second episode, including Agnes' (Kathryn Hahn) comments about Dottie's roses "blooming under penalty of death," and the on the nose exchange between Agnes and the devilish neighbour. During this exchange about organising the talent show, Dottie mentions that "the devil is in the details," to which Agnes responds with "that's not all he's in."

Given that Agnes is speculated to actually be Agatha Harkins, a famous witch in the Marvel Universe who helps Wanda strike a deal with Mephisto in the comics, who is to say that Dottie is not either Mephisto (or being controlled by the demon) and Agnes is trying to subtly reveal this to Wanda?

We know Mephisto has the power to shape shift, so he could have even character the Dottie persona as a disguise to incorporate himself into Wanda's world and using Dottie's position in the neighbourhood to conduct his sinister plans.
