Agatha: Darkhold Diaries - or perhaps Agatha All Along - will arrive on Disney+ next year, and there's a lot of intrigue surrounding how the Disney+ series is going to deal with the fallout from WandaVision.
In that series, the Scarlet Witch took control of the people in Westview, essentially torturing them so she could get a happy ending alongside The Vision and her make-believe children, Billy and Tommy. S.W.O.R.D. knows what happened, of course, but what will the rest of the world think about the Avenger's actions?
According to a rumour shared by @CanWeGetToast, the Westview incident has been covered up and dubbed an "Avengers Training Exercise." As a result, the general public is unaware of what Wanda Maximoff did, preserving her status as a superhero.
However, not everyone is buying it and there are a group of Redditors (or whatever the MCU's equivalent is) who come together to try and figure out what really happened...and some of them are said to be from Westview! That would explain why so many WandaVision characters are returning, anyway.
Very few official plot details have been revealed for Agatha, though we expect to see the series revolve around Agatha tracking down Billy Maximoff who, like his comic book counterpart, has been "reincarnated" as Billy Kaplan. Mephisto is also expected to appear, possibly played by Sacha Baron Cohen.
Various scoopers have claimed the story will primarily feature the descendants of Evanora Harkness' coven - now known as the Salem Seven - coming back to claim their revenge on the woman who killed their mothers. This investigation may well be what alerts them to Agatha's presence in the town.
Whether the witch is going to go from villain to anti-hero across the course of this series remains to be seen, though it seems likely. If nothing else, we're expecting the Disney+ series to set the stage for more mystical movies and TV shows, likely revolving around the mystical corner of the MCU.
Whatever happens, we're heading back to Westview because the show's supporting cast will feature several familiar faces from WandaVision, including Emma Caulfield Ford (Sarah Proctor), Debra Jo Rupp (Sharon Davis), David Payton (John Collins), David Lengel (Harold Proctor), Asif Ali (Abilash Tandon), Amos Glick (Dennis), Brian Brightman (Sheriff Miller), and Kate Forbes (Evanora Harkness).
Other additions include Aubrey Plaza, Joe Locke, Sasheer Zamata, Ali Ahn, Miles Gutierrez-Riley, Okwui Okpokwasili, and Maria Dizzia.
Agatha: Darkhold Diaries is currently expected to premiere on Disney+ sometime in 2024.
