Warning - This article contains spoilers for WandaVision Episode 7.
“Episode 7” of WandaVision opened the flood gates for everything that’s coming at the end of the MCU’s first season of Disney+ content. With a fully-powered Monica Rambeau, a newly revealed Agatha Harkness, and a Hex on the verge of combusting, Wanda and Vision’s near future is set to take some wild twists and turns.
While Wanda created an expansive reality for herself and her family in the town of Westview, “Breaking the Fourth Wall” brought its second witch into play as Agnes unveiled her true identity. Inducing a mind trip in Wanda and teasing a nefarious plan coming in the next couple of weeks, Agatha showed of her magical prowess and put Wanda on notice that she’s a force to be reckoned with.
Looking at Agatha’s basement, which turned out to be her evil lair, there is an interesting Easter Egg that could hold some dark teases for the MCU’s imminent future.
AGATHA IN POSSESSION OF THE DARKHOLD?
In the shocking final scenes of "Episode 7" of WandaVision, a concerned Wanda enters Agatha Harkness' basement and discovers a hidden lair filled with magic artifacts. The artifact that stuck out the most thanks to a few seconds of focused screen time was a glowing book, one that fans are theorizing is the MCU’s version of The Darkhold.
Looking back at 2016’s Doctor Strange when Stephen Strange is assisting Wong in Kamar Taj, there is a notable book missing from the Ancient One’s private collection in the library at Kamar Taj. In regard to the collection, Wong claims that "those books are far too advanced for anyone other than the Sorcerer Supreme."
A theory that has emerged in certain fan circles is that this missing book is The Darkhold itself, one that's now landed in Agatha Harkness’ possession and is sitting in her Westview basement.
IS THIS THE MCU’S REAL DARKHOLD?
In Marvel Comics, The Darkhold is also known as The Book of Sins and was authored by demonic gods who were the first practitioners of dark magic. The book has been owned by some of Marvel’s darkest characters such as werewolves and zombies and is even involved in the origins of Marvel’s earliest vampires as well.
The interesting part about the Darkhold’s history is that it’s been seen on-screen twice over the past few years. It played a key role in the Ghost Rider/Framework storyline in Season 4 of Agents of S.H.I.E.L.D. and as a part of Morgan Le Fay’s plot in Season 3 of The Runaways.
Should this book in Agatha Harkness’ lair turn out to be the Darkhold, it would seemingly prove that everything in the other two shows is definitively not canon in the MCU.
As for the future of Phase 4, this book could be something important if it plays into the plot of Doctor Strange in the Multiverse of Madness. The sequel is confirmed to tie directly in with the plot of WandaVision, and this could prove to be another connection between the two MCU entries.
If the Sorcerer Supreme realizes that he's missing the Darkhold, he may go on a sling-ring trek to find it and return it to Kamar Taj. On a larger scale, this could also mean that fans haven't seen the last of Agatha if she keeps her hands on the book and ends up facing the powerful Doctor in the future.
In the end, fans will have to wait and see if this book turns out to be the Darkhold and if it plays into the story more meaningfully during WandaVision, especially knowing Agatha Harkness is in possession of the book and its dark capabilities. However, the ramifications of these results could potentially be huge for both the MCU’s TV past and its big-screen future.
WandaVision will continue when “Episode 8” premieres on Friday, February 26, 2021.
