After nine intriguing episodes, Marvel Studios' first Disney+ TV series has finally concluded, perhaps with more questions than it has answers. some big revelations to keep things interesting.

Of course, the biggest reveal was of possibly the most entertaining villain the MCU has ever produced, the dark witch Agatha Harkness (Kathryn Hahn). As fun as she was, now that WandaVision is over, there still remains a lot of facts about Agatha that don't add up or simply weren't explained.

Señor Scratchy

Two pictures of Senor Scratchy the rabbit being held by Agatha and Billy Maximoff. The first is in black and white classic sitcom-style, the second is in color with Billy feeding the rabbit.

One of the biggest points of fan speculation over the course of WandaVision centered on Agatha's adorable rabbit, Señor Scratchy. Aside from it being one of the few animals inside the Hex, Señor Scratchy had an exceptionally suspicious name.

In the early days of WandaVision, this was enough to call attention to "Agnes." So when she revealed herself as Agatha Harkness, fans believed they were right about Señor Scratchy being either her son Nicholas Scratch or Mr. Scratch, (commonly known as either the Devil or Mephisto). Instead, Señor Scratchy is just a rabbit with a fan-baiting name.

Westview But Not Lagos

Left picture is Wanda creating the Hex in Westview in an explosion of red chaos magic. Right picture is Wanda in Lagos in Captain America: Civil War before she accidentally sets off a bomb with her magic.

One of the biggest questions remaining after the end of WandaVision, which has been around since Agatha revealed herself to Wanda, is why Westview was the reason Agatha was drawn to Wanda's power.

While the creation of the Hex was a massive explosion of magic that understandably drew the curious Agatha, Wanda's costly mistake in Lagos was far more public. If Agatha was looking for another magic- to drain, then Wanda's fall from grace and destroying the Wakandan embassy should have caught Agatha's attention far sooner.

The Darkhold

Two pictures of the Darkhold, the evil book of the damned. In the right picture it is being studied by Agatha.

The WandaVision season finale reveals that Agatha has access to the Darkhold, the book of ultimate sin made of dark matter from the Hell dimension. While the Book of the Damned hasn't been seen in any Marvel movies, it has previously appeared in the MCU in TV form on Agents of SHIELD and Runaways.

There are several places the book has been since then, including the Hell dimension itself, where it was taken to by Ghost Rider. The question is then, where and how did Agatha Harkness get her hands on the Darkhold?

328 Years Later

Left picture is Agatha as Agnes in exercise gear in one of the sitcom episodes. Right picture is Agatha 300 years ago, tied to a stake, at the birth of her powers.

The real-world Salem Witch Trials came to an end in 1693, and in WandaVision, it is the birthplace of both Agatha Harkness and her mysterious magical powers. The problem is that the show doesn't explain what Agatha got up to in the 328 years she's been alone in America.

While no fan should have expected a full exploration of Agatha's movements over the centuries, as that's not what WandaVision's about (and it certainly doesn't have time to do so), it doesn't make sense that Agatha's vast magical power has seemingly been in hiding for over three centuries.

Magical Sponge

Two pictures showing Agatha's power to absorb magic. Left is present day absorbing Wanda's magic, the right is 300 years ago absorbing her family's magic.

In the WandaVision season finale, during the first battle between the soon-to-become Scarlet Witch and Agatha Harkness, Agatha casually brushes off all of Wanda's powerful magical attacks.

Even more than that, it's revealed that Agatha is actually absorbing the magic, just as she did to her own coven and mother when they tried to execute her. It seems Agatha's primary power is the ability to absorb the magic of others, but the show never explains how she came across this rather specific power.

The Fly On The Curtain

Left picture is the sinister cicada bug on a curtain, right picture is a concerned Wanda looking at the bug.

One of the biggest problems with WandaVision is that both on-screen and in real life, there were a lot of teases or suggestive moments for things that didn't happen or didn't pan out (and many of these had to do with Agatha).

One moment in particular that in retrospect doesn't make any sense came at the end of episode 7, where Wanda is in Agnes's house and the camera focuses on a cicada on the curtain. Fans were certain this was another hint towards Marvel's Devil-substitute Mephisto, who sometimes appears as a fly, but it ended up being just a bug that the camera lingered on for no reason.

The Immortal Agatha Harkness

Given that Agatha Harkness isn't the focus of WandaVision and wasn't really in the show that much, it's amazing that the series managed to show as much of her backstory and motivations as it did. For example, it revealed that Agatha is over three hundred years old. In fact, she may actually be immortal.

However, what the show doesn't explain is how this is possible. She certainly has powerful magical abilities, including being able to absorb magic from other people, but viewers are still left in the dark about how Agatha came to be immortal.

Ralph Bohner

Fietro Evan Peters Ralph Bohner

Undoubtedly, the most talked-about moment in all of WandaVision was the appearance of Evan Peters as the "recast" Pietro Maximoff/Quicksilver, who he memorably played in the X-Men movies.

For the majority of fans, the most contentious moment in the show was the reveal in the last episode that "Fietro" (Fake Pietro) was a nobody called Ralph Bohner and was in no shape or form linked to the idea of the Multiverse. While not necessarily a bad thing, it really makes no sense that Agatha would send someone to meet Wanda who looks nothing like her brother, especially if there was no other reasoning behind it other than simply that Ralph was the nearest man to her at the time.

The Runes

Runes Wanda Agatha

In episode eight of the series, Agatha manages to subdue Wanda's magic through the use of special enchanted runes on the wall of her sanctum to create a basic protection spell. It turns out Wanda is a quick study with a good memory because, at the end of episode nine, she turns the tables on Agatha by drawing those runes on the sides of the Hex, thus depowering Agatha while she's there. The confusing thing is, though, they don't fully depower her.

Agatha clearly still has the power of flight. Most importantly, the Hex is gone anyway a few minutes later so surely any spell cast on Agatha by Wanda would disappear.

Agatha All Along

Two pictures from the Agatha All Along song. Left is black and white Agatha doing real magic at Vision's magic show from Episode 2, right is Agatha as the director in the Episode 7 fake Wanda interview.

Arguably the greatest moment in WandaVision arrived at the end of episode seven, where nosy neighbor Agnes was revealed as the evil witch Agatha Harkness, and the audience discovered everything weird in the series thus far had been her doing all along (revealed in a catchy song).

While the moment is a highlight for most fans, the part that doesn't make sense is that it's basically a complete lie. Agatha strung along the deception a little, but as the very next episode reveals, she's just as much in the dark about Wanda's creation of the Hex as the audience. By the end of WandaVision, it's plain to see that everything was clearly Wanda all along, not Agatha.
