Looking back at my WandaVision theories on Agatha, the twins and Mephisto

After the Agatha reveal in February 2021, I traced the twins and Agatha to their comic roots, tied the Nexus ad to the Infinity Stones and doubted Quicksilver was evil. here is what I expected before the finale settled it on March 5, 2021.

WandaVision episode 7 picked up after Wanda expanded the Hex, borrowed its style from The Office and Modern Family, and ended by revealing it had been Agatha all along. Before the finale aired on March 5, 2021, my main theories were that Wanda built the Hex herself with Agatha pushing her, that Agatha might be possessed by Mephisto or Nightmare, and that Evan Peters' Quicksilver wasn't the villain he seemed.

The episode moved both storylines forward in many ways. Here is everything I picked out from it, and what I expected to happen next.

Billy and Tommy's comic roots tie them to Mephisto, but I thought the show might skip that

It was clear by this point that Billy and Tommy were becoming Wiccan and Speed. In the comics, the twins were introduced as Wanda's children in the graphic novel Vision and the Scarlet Witch, which followed the pair as they made a life in New Jersey. There was a twist, though. Because Vision was unable to have children, Wanda unwittingly used fragments of Mephisto's soul to give them life, and they were eventually reabsorbed by the villain.

The pair were later brought back and reincarnated under surrogate parents, becoming mutants. Because Vision can't have kids and they're technically blood relatives to different people, the comic versions aren't really Wanda's children, but they are at the same time. That family tree might even outdo something as complicated as Game of Thrones.

I felt the show could potentially combine these two arcs, skip the devilish details and give us a more streamlined story. As the weeks went on, I'd grown slightly less confident that Mephisto was the villain, and keeping them as her kids by birth raised fewer questions. That would make the pair the first two naturally born superheroes in the MCU, and it was likely they would open the door for other mutants down the line.

Speed and Wiccan's powers explain why they were so sought after in Westview

The twins possess pretty much the same skill set as the Scarlet Witch and Quicksilver, but they also have unique abilities. Speed can alter the kinetic energy of objects through his touch, similar to Gambit of the X-Men. This makes objects vibrate and overheat until they eventually explode.

Like Wanda, Wiccan can fire energy bolts, and he can also read minds. He's definitely the one to look out for. Among the magic community he is highly regarded, and Doctor Strange has even predicted that he will one day grow up to become the most powerful superhero in the universe. With that in mind, it made sense why the pair were so sought after in Westview.

Both are also members of the Young Avengers, and with Hailee Steinfeld playing Kate Bishop, it seemed the studio was setting the team up.

Agatha Harkness has a long comic history with Wanda

In the comics, Agatha was born circa 11,000 BC, and after contact with a cosmic being, she slowly made her way through the world mastering her magic. By the 17th century she had settled among an English colony in Salem, where she formed a coven of witches. The Puritans tried to uproot them with the Salem witch trials, which she survived.

She then settled in New Salem, a made-up magical community in the Marvel universe, and as its strongest sorceress she became its leader. She had an evil warlock son, Nicholas Scratch, who was probably referenced in Agnes' rabbit Señor Scratchy, which is also a nickname for the devil. After World War II, Agatha joined the US Army, and shortly after, she posed as a nanny for Reed Richards and his wife to keep an eye on their baby Franklin.

Agatha was eventually captured by the Salem's Seven, taken back to New Salem and burned at the stake. Wanda went toe to toe with them, and not long after, she fell pregnant. Agatha's spirit appeared to her on Halloween, when the barrier between worlds was thinnest, and later manifested to reveal the truth about her babies. Though she became a mentor to Wanda, Wanda ended up killing her, and since then the character has drifted in and out of certain arcs.

The Office style opening shows Wanda losing control of the Hex

The series had chronicled the evolution of the sitcom, from very standard shows to ones that broke the fourth wall, and both The Office and Modern Family were presented as documentaries. Unlike the other episodes, this let us into Wanda's thoughts, and it revealed a lot about the characters. I hoped we'd eventually get more decades, maybe even Professor X showing up in a 2020s episode.

Wanda wakes up explaining how her fear and anger got the best of her, and she waves her hand in emotion in a way that mirrors spell casting. I read that as what she does when she's backed into a corner. The Hex is built on her anguish, and she prefers to magic her problems away instead of tackling them head on.

Tommy and Billy enter wearing their comic colors: green for Speed, and red, blue and black for Wiccan. Their game controllers flip through time, from GameCube to Atari, before they switch to Uno cards, which showed me she'd lost control. Billy says his head feels weird, and with his psychic abilities, he was likely picking up all the extra people Wanda had pulled in.

Hexagons, a queen bee and a cereal box all pointed to bigger things

The duvet and Vision's pillow are covered in hexagons, but Wanda's pillow isn't, likely showing that she's not subject to the same things as him and the rest of the town. In nature, hexagons appear in beehives. Preparing for the series, I reread classic storylines leading into House of M, including Avengers Disassembled, which featured a queen bee character named Adriana Soria who controlled her subjects through a hive mind. That's very similar to how Wanda alters the actions and memories of those around her.

The graphic novel that set up the events of House of M also used hexagon imagery throughout. The duvet's hexagons within hexagons cement how the Hex had expanded to encompass more, which Wanda clearly regrets. She also says we built the Hex rather than I, which highlights the Agatha reveal at the end.

Wanda's walk down the stairs mirrors a shot from the previous episode, perhaps showing the decades becoming interchangeable. As the milk changes, one version carries a missing child poster, and kids were slowly disappearing. If you line this up with behind the scenes images from Spider-Man 3, it looks like there are missing kids there too, so perhaps Agnes ends up doing this on a grand scale, and that may be how the properties are linked. The maze on the Sugar Snaps box could nod to the characters navigating what they've been pulled into, while the purple elephant and the phrase an elephant never forgets contrast with how everyone's memories have been stripped, though I admitted that one was a big reach.

My theory was that Wanda created the Hex and Agatha pushed her

The intro flashes Wanda's name alone, with Vision only arriving at the end, and the credit reads created by Wanda Maximoff. I still believed Wanda created the Hex herself, and the person who pushed her into it was Agnes, or rather Agatha. Agatha could be draining Wanda's life force, which might be why the Yo Magic commercial showed someone starving to death while focusing on a smaller problem.

At the temporary SWORD retreat, the Hex now covers a wide area, Under the Dome style. Hayward says they launch today, and I expected he was planning an all out assault for episode 9. I thought the episode in between would be a flashback.

Inside the Hex, Vision wakes up at the circus. Hayward's henchman is now a strongman, and Darcy is an escape artist, having been sucked in while handcuffed to a car, a detail I appreciated. Wanda tells the kids she doesn't have the answers. She believes everything is meaningless, but there are dark forces at work, likely trying to weaponize her kids. Agatha's purple shirt, her comic color, was the first hint, and her mole is typically the mark of a witch, as someone pointed out to me.

SWORD's plans for Vision may explain why Wanda snapped

Jimmy and Monica discuss the Cataract project, and as we predicted, Hayward was trying to weaponize Vision but couldn't bring him back online. The previous episode hinted that times got desperate during the five years between the snap and the blip, and likely because of fear across the world, he turned back to recreating Ultron or a defense program of the same kind.

At the end of Endgame, Wanda seemed to be accepting Vision's death. It's possible that when she learned he was being turned into a weapon, she completely snapped. As a synthezoid, Vision doesn't have the same rights as a human, so she would have no control over what happened to his body. That's likely why she broke into SWORD, and because that's a crime against a law enforcement agency, she had to go on the run.

Monica then meets her friend, the major. That was a slightly disappointing reveal, and I didn't believe this was the aerospace engineer; I thought they'd probably appear toward the end. A circus sign reading Fool the Guesser felt like the showrunners making fun of us fan theorists for getting everything wrong, though I did get the Agnes theory right.

I tied the Nexus ad to Wanda's grief and the Infinity Stones

The woman from the earlier ads returns, clearly representing Wanda. Every ad pulled from a trauma in her past, and this one is her grief over Vision. She sits alone on a bench, as Wanda would have at the end of Endgame, and lies in bed alone, while the antidepressant Nexus is mentioned. In Age of Ultron, Nexus was the hub where all internet information flows, but in the comics, Wanda is a Nexus being, someone who is the same across all dimensions of the multiverse. Nexus beings are keystones of existence who can affect probability and the future.

If our theories about the ads and the Infinity Stones were right, we might have a double up. The toaster resembled Vision, who was nicknamed toaster in the comics, so its central light could be the Mind Stone. The watch dealt with time, the Hydra soap resembled the Tesseract, the Lagos red liquid was similar to the Reality Stone, and Yo Magic, dealing with death, could be the Soul Stone. Nexus also centers on reality, perhaps because of that stone's multiple states, or maybe we got Lagos wrong and it was the Power Stone.

The plot to kidnap the children could be a red herring, and recreating the Infinity Stones may be the show's main objective. They're paramount to keeping reality stable, so recreating them would stop the main timeline from going down a dark path. The trailers showed what looked like it could be the Mind or Soul Stone and possibly the Tesseract, but we couldn't know for definite until we had all the episodes.

I suspected Agatha might be possessed, while Monica became Photon

Agnes' house is the same home from Bewitched, as someone pointed out to me, further pointing to the reveal. Wiccan can't read her mind because she's empty, which could highlight that she may be possessed, potentially by Nightmare or Mephisto. I was still going with the Mephisto theory. Agatha was a good character in the comics for most of her history, and the basement and post credits scene suggested more people were involved. We still hadn't seen the enigmatic Ralph, and I believed he might be the big bad behind it all.

Outside the Hex, Monica's attempt to re-enter initially fails, but she tries again. I absolutely loved this scene, and it was one of the highlights of the show for me. The transformations are incredible, and seeing her become Photon was fascinating. Because of the similarities in uniform, I thought we could now fully confirm they were one and the same. In the background we hear audio from Captain Marvel, quotes from Carol and her mother, which show that we all have the ability to be a hero.

Monica sees radio waves inside the Hex, and it's possible the towers broadcast the signal, though I wasn't 100 percent sure. "I'm an easter egg hunter not a radio engineer."

Vision has never had a choice, and Agatha seemed to be blocking the truth

On the road, Darcy tells Vision the truth about what happened to him. That made me realize Vision has never had choice or agency. JARVIS was created by Tony to be a servant, then put into a body by Ultron to be a weapon of mass destruction. SWORD wanted to use him for their own means, and now Wanda keeps him around to keep herself happy. I felt the show would be about him gaining his independence while others still wanted to use him.

I also felt the roadblocks were put in place by Agatha, since whenever someone got close to the truth, she made them deviate. Whatever her end goal, she definitely wanted to keep the Hex going.

Monica arrives at Wanda's in a scarlet hoodie similar to her costume and tries to warn her about Hayward. Wanda makes her levitate, and she comes down with a superhero landing. The neighbors stop to stare, and they could all be servants of Agatha; I wasn't writing anything off, and I suspected Dottie. Monica knows Wanda is good deep down and won't kill her, and it's only when Agatha arrives that she can't get through to her. Vision, tired of the Truman Show level distractions, decides to fly to Wanda himself.

Agatha's basement, the Darkhold and a Quicksilver I hoped was good

Inside Agatha's home, Wanda realizes something is wrong, likely because reality is stable there. A fly on the curtain had green on it that reminded me of Nightmare, and I thought a bigger bad would be teased before becoming a staple villain, similar to Thanos. The twins' food is half eaten, potentially because they were drugged, and the glasses have hexagons in their star pattern.

In the basement, Wanda finds an ancient cavern of roots and branches, and the aspect ratio changes, showing this is the real world. There's a sect similar to a coven and what I believed was the Darkhold, an ancient book of spells from the comics, Agents of SHIELD and more. I only questioned it because the design was different, but it would be something Agatha would possess, and it could show how the reality was created. Agatha says Wanda isn't the only magical girl in town, which made me wonder if the women's meeting in episode 2 was all of Westview's witches, though that might be a reach, and Geraldine isn't a witch.

Agatha strokes Señor Scratchy as she carries her cat Ebony in the comics, an animal that can change into a large black panther; I thought they switched to a rabbit so the reveal wasn't too obvious. Her brooches reappear, likely the key to her powers. During the twist on The Munsters theme, we see her magic against Evan Peters' back, and I thought that hinted she was controlling him and that he would probably be a good guy. Many people theorized Quicksilver was Mephisto or Nightmare in disguise, citing the quotation marks around his name on his Funko Pop, but I thought that was because he was Peter in the Fox universe and now played Pietro, a recast joke. His Halloween costume came from the comics, his post credits outfit has the blue and white, and Agatha's magic on him cemented for me that he wasn't in control. I hoped Vision would free Monica and knock him out of it, because I wanted the X-Men and Hugh Jackman back.

My verdict on episode 7 and the Jimmy Woo spin-off tease

I was absolutely in love with the series at this point. Not since Westworld had I been so captivated by a season's mysteries. I liked the Scarlet Witch and Vision in the comics but they were never my favorites, and, as with Captain America and Iron Man, Marvel moved these C-listers into major stars with arguably one of the most fascinating arcs in the MCU. I'd rewatched every episode about four times, and the opening two, which I wasn't too hot on, played better with the added context. This was another excellent entry, and I enjoyed it more and more as they pulled back the curtain.

It also looked like we might see more of Jimmy Woo. The mind behind Teen Wolf teased on Twitter that a Disney Plus spin-off might have been greenlit, posting his Xbox controller in front of what looked like agency documents, with Park's head superimposed onto Daniel Craig's James Bond. He hadn't confirmed anything, and he could have been building hype for a pitch. Still, it could open the door to Agents of Atlas, a group Jimmy was a member of, and with how popular he is, I thought that if Marvel did something with him, a secret agent show would be one of the best avenues.
