WandaVision Finale Explained: The Post Credits Scenes and My Villain Theory

Monica Rambeau's Skrull contact, Wanda's Darkhold study and why I suspected Chthon and Mephisto were behind it all

WandaVision's finale was truly fantastic. A lot of what we thought would happen did happen, and a lot of what we hoped for didn't. There's a ton to break down, starting with the two end credits scenes, what they set up for the Marvel Cinematic Universe, and my theory on the villain of Doctor Strange in the Multiverse of Madness.

After that comes the whole episode, scene by scene, from the Wizard of Oz nod to the Ship of Theseus to Vision's final goodbye.

Monica Rambeau's Skrull visitor points to Nick Fury in space

The first end credits scene opens with Jimmy Woo gathering everybody and naming spots for people to set up, like medical going in the pharmacy, as they start gathering evidence. He meets up with Monica Rambeau and asks where Darcy is. Monica explains that Darcy said debriefs are for the weak. She came in for one scene to hit Hayward and trap him so they could catch him, then she left, a bit like White Vision. Hayward is taken into custody for a string of crimes. He tried to frame Wanda and kill her, stole Vision's body and turned him into a weapon against the Sokovia Accords and Vision's own will, and shot at some kids, real or not.

Then an unnamed agent tells Monica they're asking for her in the theater. The agent follows her in and reveals she's a Skrull. Skrulls are no surprise to Monica, who was the little girl, Maria Rambeau's daughter, in Captain Marvel. The scene doesn't say who this Skrull is, but she says she was sent by an old friend of Monica's mother: "He heard you've been grounded. He'd like to meet with you." When Monica asks where, the woman points up.

Since it's a he and an old friend of Maria's, she is most likely referring to one of two people. One is Talos, leader of the Skrulls we know so far, who also appeared in the post credits scene of Spider-Man: Far From Home. But I think she's most likely referring to Nick Fury, who worked with Captain Marvel and Maria Rambeau. We know he's in space, in what we believe to be S.W.O.R.D.'s headquarters, which in the comics is located above Earth. That's why she points up.

Wanda's Darkhold study suggests her twins are alive and in distress

The second end credits scene has Wanda alone in the mountains drinking tea. This scene was shot in New Zealand, although it's unclear if that's where they want us to believe she is. She goes into the kitchen for more tea, but the shot continues into the bedroom, where the Scarlet Witch hovers over the bed in true Doctor Strange fashion, studying the Darkhold. She seems to be casting spells, with circles surrounding her. When Agatha reads from the book earlier, you can see circles on the left page too, and I believe these are different dimensions, universes or realms, whatever Marvel ends up calling them.

Some people wondered if there were two Wandas here. It looks to me like she's astral projecting, the way Doctor Strange studied while sleeping in his movie. But as Agatha said, Wanda is stronger than the Sorcerer Supreme, so she can be up drinking tea and studying at the same time, which seems to be more than Strange could do.

Then she hears her children: "Mom, help." Not only does this tell us her kids are alive somewhere, it tells us they're in distress, and at the very end it seems Wanda knows where they are. My theory is that Wanda felt them and knew they still existed, just not in this earthly realm, so she searched other realms with those circles until she found them. I believe they could be in the hell dimension.

My theory: a villain combining Chthon and Mephisto

We never saw Mephisto, but it makes sense that Tommy and Billy would be stuck in the hell dimension. In the comics, Wanda's twin boys are shards of Mephisto's soul, and eventually he takes them back and they cease to exist. Something similar could be happening here. We knew the boys weren't Vision's, because he's a synthezoid and can't have kids, but Wanda had to get pregnant somehow. Perhaps they were part of Mephisto's soul and returned to his dimension. Agatha called the Darkhold the Book of the Damned, and the damned go to hell.

Agatha confirmed the book was the Darkhold, which to me meant the evil elder god Chthon, Mephisto or somebody like that was coming. When Agatha says "surrender your powers," she makes clear Wanda wasn't born with them; they were given to her, so she can give them up. After Wanda becomes the Scarlet Witch, Agatha tells her, "You have no idea what you've unleashed." What she means is chaos magic. The Darkhold was created by Chthon, the original creator of chaos magic, who put part of it in the book. In the comics he put part of it inside Wanda so he could eventually return to the earth realm, and Agatha mentions a whole section of the Darkhold dedicated to the Scarlet Witch, most likely because that's how he returns.

So my theory was that Wanda would tear apart universes searching for her children, and Doctor Strange, whose job is protecting the main reality, would realize she had opened a way for Mephisto, Chthon or a combination of the two to reach Earth. Scott Derrickson was originally directing the film before Sam Raimi took over, both horror directors, which is why I expected some evil being, and I believed it would be a mix of Chthon and Mephisto.

The fight opens with a Wizard of Oz nod and White Vision's arc reactor

The episode picks up right where episode eight left off, with Agatha holding the twins hostage. Wanda says her powers work outside, and Agatha says she's counting on it, because she wants to take Wanda's chaos magic. As Wanda uses it against her, Agatha starts to drain it. When Wanda drops a car on Agatha and sees only her boots underneath, that's a direct reference to Dorothy's house landing on the Wicked Witch of the East in The Wizard of Oz.

White Vision arrives. Wanda thinks it might be the real Vision, but he's there to kill her, and her Vision saves her. Look closely and White Vision has an arc reactor where the Mind Stone would be, just like the one that powered Tony Stark's suits. Could it be Tony's technology? Did he give S.W.O.R.D. permission, or did they use it without his consent? This could set up Armor Wars, the War Machine project about what happens when Tony's technology falls into the wrong hands, and it could bring White Vision back for it.

Vision tells Wanda he knows why she made this world. She says she can fix it, and he asks, "Can you?" He knows that without the Hex he'll go away, so what he's really asking is whether she can let go of him and the kids. Agatha cracks a joke about Wanda's ex and her boyfriend in the same room, then Wanda says "this is our home" and Vision says "then let's fight for it," leading to Vision against Vision and the Scarlet Witch against Agatha Harkness.

The Quicksilver we believed in sadly turns out to be Ralph Bohner

Monica confronts who we believed to be Quicksilver, but sadly he turns out to be Ralph Bohner, which is a weird choice, Marvel. This is the Ralph Agatha teased all series, and he tells Monica, "This is my man cave, a place to chillax while the missus is stirring up trouble." Under her control, he believes Agatha is his wife.

The big question is whether he has powers or matters. I believe Ralph could be the person in witness protection Jimmy Woo talked about. Ralph Bohner is a weird name, one he laughs at himself, so it could be made up, and hopefully he has a bigger role. That may not be the case, though. When Monica rips off the necklace Agatha uses to control him, he begs her to spare his life as though he can't do anything. If so, it's a weird move to bring Evan Peters in as a fake Quicksilver, and perhaps it's Marvel telling us the Fox X-Men are dead and aren't coming to the MCU.

Hayward lies while Jimmy Woo calls a mysterious Cliff

White Vision says Wanda must be neutralized and goes for Vision's Mind Stone, most likely because he thinks it's real. We learn later that Vision was created from the part of the Mind Stone living in Wanda, and that it can't survive outside the Hex. S.W.O.R.D. probably thought it was real too. They then can't get anything through to White Vision because his systems are overloaded, which implies he's starting to think for himself.

Hayward is truly a villain and a jerk. He says he'll lie because no one knows there are two Visions now that Wanda isn't broadcasting, and that no one will care once he kills Wanda and makes her out to be a villain. Our hero Jimmy Woo steals a phone, teases Hayward that the FBI will arrive in an hour, escapes the cuffs and calls his team.

Jimmy talks to someone named Cliff, who could be one of two comics characters. One was formerly of the Air Force and investigated a possible conspiracy, a very minor character. The other was a member of the alien Collective Intelligence, a sleeper agent living as a normal human until recalled, who sabotaged their ship and saved Earth. They could change that into a Skrull storyline, and since one of the FBI agents was a Skrull, it could line up.

Agatha says Wanda's power exceeds the Sorcerer Supreme

Agatha name drops the Darkhold and its Scarlet Witch chapter, then says Wanda's power exceeds that of the Sorcerer Supreme, meaning her chaos magic is stronger than Doctor Strange's magic. In Avengers: Endgame, the Ancient One told Hulk that Strange is supposed to be the best of them. But Wanda isn't a master of the mystic arts, so she doesn't count there, and the Ancient One said best, not strongest. There's more to being the best than strength.

The circles on the book's left page are most likely realms or dimensions; Mephisto is in the hell dimension and Nightmare is in the dream dimension. Thor mentioned nine realms, but I believe those are different and refer to worlds and planets.

When Wanda says she isn't evil, Agatha releases the townspeople. Dottie answers Vision's old question about where all the children are: Wanda kept them trapped in their rooms, and Dottie asks her to let her daughter out. The twins, through Billy's psychic powers, realize what's happening. The townspeople feel Wanda's pain and have her nightmares when they sleep, which points again to my theory that Mephisto, Chthon and maybe Nightmare will be merged into one villain influencing Wanda.

Westview turns on Wanda and the family fights like The Incredibles

The townspeople attack Wanda, and it becomes too much. She has a meltdown and starts choking them with her magic. When Agatha tells her to release them, she drops the Hex for a moment and S.W.O.R.D. moves in. Because Wanda tied her family to this reality, Billy, Tommy and Vision start to dust away like people did with Thanos's snap, so she puts the Hex back up.

The family unites to fight, looking just like The Incredibles, which was on the theater display a few episodes earlier. It's Vision against Vision, Wanda against Agatha, and the boys take out the military rather easily. Meanwhile Monica saves the twins from Hayward, absorbing bullets with the new powers the Hex gave her. Billy and Tommy are too powerful for Hayward, who flees because he's a little wimp, until Darcy shows up and then disappears for the rest of the show. There's a lot of bailing in this episode.

The Ship of Theseus frees White Vision

Vision pulls a reverse psychology on White Vision, saying he isn't the true Vision, only a conditional one. White Vision requests elaboration, and Vision brings up the Ship of Theseus thought experiment. The ship sits in a museum, its rotting planks replaced over time. When no original planks remain, is it still the ship? And if you restore the old planks and rebuild them, is that the ship? The answer is that neither alone is the true ship, but both are.

Neither Vision is the original, yet both are part of him. White Vision has the vibranium but not the Mind Stone, while Wanda's Vision has everything the stone gave him and the original's memories. Vision awakens White Vision's mind and frees him from S.W.O.R.D.'s control, which was running through the reactor in his head, and his eyes become more human. Now he has the original parts and the memories, making him the real Vision. Then he suddenly realizes he is Vision and leaves, and we don't know where. I was sure he would return at some point in the MCU.

Wanda's runes and her crown turn the tables on Agatha

Wanda uses the mind tricks she used on the Avengers in Age of Ultron to take Agatha back to where Agatha killed her mother and her coven. Wanda manipulates the memory and the witches come back to life, until Agatha turns it around. The witches say Wanda is the one written about, referring to her Darkhold section, which was written by Chthon, and call her a harbinger of chaos. A harbinger is a person or thing that signals the approach of another, so Wanda signals the approach of chaos, or of Chthon, who I believed would be a big bad and a villain in the Doctor Strange sequel.

Agatha says power isn't Wanda's problem, knowledge is, as the Scarlet Witch crown appears on Wanda's head. Agatha offers a deal: give up her powers and she'll fix the spell so Vision and the kids never go away and the people of Westview stop hurting. Back in the real world, Wanda throws her powers at Agatha but sometimes misses, which confuses Agatha. It's a plan. Wanda is casting the runes Agatha taught her in episode eight, so within the Hex only Wanda can use magic. Once Agatha takes the powers, she goes back on her deal, saying the spell can't be changed, and tries to kill Wanda, but can't.

Wanda says she doesn't need Agatha to tell her who she is, and the crown forms again even after she gave away the chaos magic. That means she's truly destined to be the Scarlet Witch; in the comics she was marked personally by Chthon. She takes the power back, unlocks more chaos magic, and we see the true Scarlet Witch on screen for the first time. Agatha warns she'll need her help because this evil being is coming. Wanda says she'll know where to find her, trapping Agatha in a prison of the mind as nosy neighbor Agnes: "I'll be seeing you, Agnes."

Vision's goodbye leaves the door open

Vision tells Wanda he knows she'll make everything right, but not for them, and Wanda agrees, meaning Vision and the boys have to go. She releases the Hex, and Westview returns to normal. At home, they tuck in the twins and tell them they're proud. Wanda's lines about family being forever, and never truly leaving each other even if they tried, tie into the post credits scene where she hears the boys alive somewhere.

Vision asks, "What am I?" Wanda answers what we've all wanted to know. He's a piece of the Mind Stone that lives in her, physically made from wires, bones and blood rather than vibranium, a projection of her sadness and hope, and most importantly her love. He says he's been a voice with no body, referring to being J.A.R.V.I.S. for Tony Stark, and a body but not human, referring to the synthetic body Ultron built, and now a memory made real. They've said goodbye before, so it stands to reason they'll say hello again. That implies we'll see a version of him again, most likely White Vision, the original vibranium Vision with the memories.

Vision says "so long, darling," and the Hex vanishes with him and the kids. Wanda stands on the empty lot Vision bought for their home, accepts that he's gone, and walks through a town that knows what she did. She tells Monica she's sorry, and Monica says she understands, because she would bring her mother back if she had the power. Wanda says she doesn't understand the power she has, but she will, and with the Darkhold she's going to learn how to be the Scarlet Witch. She changes into her Scarlet Witch outfit and leaves. Kevin Feige said WandaVision would have one season, but that Doctor Strange in the Multiverse of Madness was basically season two. I truly enjoyed this season. I was wrong about a lot of things and right about some, but I loved every second of it.
