This article contains spoilers for the finale of WandaVision.
After nine episodes, the first Marvel Cinematic Universe series for Disney Plus has officially come to an end. WandaVision morphed from a love letter to sitcoms into an emotional ride for Marvel fans - and it did it with plenty of hidden Easter eggs and references along the way. Though the action ramps up in the season finale, there isn't a lack of those hidden (and some not so hidden) Easter eggs.
Along with the comic book references, there are callbacks to earlier moments in the MCU. Some of those are in Wanda's own life, while others apply to different characters. There are also a few pop culture nods, once again, to The Wizard Of Oz, and a few hints for the future.
The Episode Title
Throughout the run of WandaVision, each episode's title acts as reference to television sitcoms of the past. Key phrases from TV history like, "Don't Touch That Dial," and "On A Very Special Episode..." have been employed as titles. The same is true here. This time, the title is "The Series Finale."
Fans hoping for another season of WandaVision might be disappointed as a result. That title points to this episode being the end of the story for WandaVision.
The Wizard of Oz
A lot of witchy story writers love to call back to the Wizard Of Oz in various ways. WandaVision already featured a handful of Oz nods in previous episodes, but in the season finale, there are four. The first is that Oz The Great And Powerful is the movie playing at the local theater at the top of the episode.
Agatha references Wanda's "pretty redhead" at one point, which is a common enough turn of phrase. Kathryn Hahn's tone, however, calls to mind "my pretty," a phrase used by the Wicked Witch Of The West in the 1939 feature film.
When Wanda tries throwing her car at Agatha instead of using her magic, there's another nod. Her car lands, supposedly, on Agatha, and all the audience can see are Agatha's shoes. The shoes, of course, are empty as Agatha lives to fight on, but the visual of Wanda peering at the shoes in a reference to the Wicked Witch Of The East being leveled by Dorothy's house, only her shoes visible underneath it.
Finally, Agatha makes one last nod to those wicked witches during her fight with Wanda. She cackles when she has the upper hand. It's a laugh she's used in earlier episodes, and even then, it called to mind the Wicked Witch Of The West's laugh as well.
The Darkhold
There's been much speculation about just which book Agatha had in her position when Wanda found her way into the basement. Agatha title the book herself in the finale as The Darkhold. She references it as the "book of the damned," which is another name for it in Marvel comics.
A version of the book has appeared in both Agents Of SHIELD and in Runaways. Each version has a slightly different appearance than the last, and Agatha's looks even older than the other two. Interestingly, the Agents Of SHIELD storyline involved the book corrupting those who read it, though WandaVision makes no indication that will happen here, which might mean it only corrupts those who aren't already magical beings.
Wanda's Original Power
During the series, Wanda exhibits a lot of abilities she didn't previously have in the Marvel Cinematic Universe. Prior to the series, she focused on moving things with her mind and blasting energy at opponents. The one exception is her first big role in Avengers: Age Of Ultron. There, she exhibits a very different ability.
In the movie, Wanda is able to get inside people's heads and show them their nightmare. She does just that in the finale for Agatha Harkness. Her delving into Agatha's memory of her coven attempting to put her to death is even accompanied by the same hand motion Wanda originally used, though it doesn't turn out exactly the same for her.
WandaVision's New Scarlet Witch
As Wanda and Agatha fight, Wanda's magic literally makes a red crown on her head at one point. While that's a nod to the Scarlet Witch headpieces in the comics, it also foreshadows Wanda's eventual transformation into her namesake.
When Wanda fully transforms - complete with her own new magicked costume - she wears the closest ensemble she has to her modern comic book look yet. She also wears what looks to be the same silhouette she saw in her own memories of interacting with the mind stone in episode eight.
Ralph
Since the very first episode, nosy neighbor Agnes has made references to her husband Ralph. The audience wondered if Ralph was even real at one point. Though he isn't actually her husband, Ralph is definitely real.
"The Series Finale" reveals that the fake Pietro is actually named Ralph. Considering he has a headshot in his room, Ralph might even be an actor. The home that Agnes passes off as her own is actually his. She takes over his basement and uses him to do her dirty work, but Monica discovering his name on that headshot finally pays off the Ralph tease.
The Mid Credit Scene
While there's no sitcom commercial this week as Wanda lets go of her hold on Westview, but there are two scenes during the credits. The first features Monica Rambeau and a connection to her childhood in Captain Marvel.
When an agent takes Monica into the theater to chat, the agent reveals she isn't an average human after all. She's also not interested in discussing Monica's new superpowers. Instead, she's a Skrull with a message for Monica. Monica first met a family of Skrulls as a child when Carol Danvers brought Skrulls to Maria Rambeau's home. This tease might lead to Monica's role in the Captain Marvel sequel, or potentially the Secret Invasion series heading to Disney Plus. Both could feature the shapeshifting Skrulls.
The End-Credit Scene
Though the mid-credit scene focuses on Monica, the end-credit scene focuses on Wanda. Isolated in a cabin somewhere in the mountains, Wanda not only has the Darkhold, but she also seems to have learned to astral project.
This scene might place her forward in time, perhaps during the events of Doctor Strange And The Multiverse Of Madness. After all, Stephen Strange used the astral projection technique to be able to learn magic faster during the events of his own movie.
While the astral form of Wanda reads the Darkhold, however, she also hears a voice. It sounds just like Billy crying out for his mother. Though Billy and Tommy are gone at this point, they also vanished in the comics as their birth was provided by a piece of a demon's soul. Wanda eventually got them back. Whether she's hearing her sons across the multiverse or something else remains to be seen.
The mountainous landscape might also raise the eyebrows of some comic book fans. Wundagore Mountain is where Chthon originally wrote the Darkhold in the comics. It's also where Morgan Le Fay and her followers eventually imprisoned Chthon. Wundagore Mountain also happens to be where Wanda Maximoff and her brother Pietro were born.
