The season finale of Wander Vision is now available on Disney Plus, bringing an end to Marvel Studios' first TV series. It was a great series and there is much to discuss. Fortunately, we have a year to wait until Wanda returns in "Dr. Strange and the Multiverse of Madness."

If you haven't seen Wanda Vision episode 9 yet, you might want to turn back now. That's because there's an important plotline that has easily erased an important old Marvel TV show from the canon, just as Thanos has erased half of the life in the universe.

Who isn't a watcher anymore? Because I have to talk about Darkhold. Agatha seemed very casual about Darkhold, casually referring to it as "the cursed book." But the Darkhold is a big problem in Marvel Comics and in past TV shows. Just not this particular Darkhold.

Those who watched "Agents of SHIELD" will remember that Darkhold played an important role in the show's fourth season. Darkhold also appeared in the third season of "Runaways" and was used by the ancient witch Morgan Le Fay for all manner of evil.

However, it does not appear to be the same Darkhold as the one in Agatha's basement. In fact, the two seem to be completely unrelated beyond the name and the appellation "cursed book." Take a look at the darkhold seen in "Wanda Vision" and the darkholds in "Agents of S.H.I.E.L.D." and "Runaways.

See. The two books could not look more different. For starters, only one looks more magical (and evil) than the other, the so-called cursed book.

Likewise, the actual characters in the books are drawn differently. In the TV show, Darkhold is a traditional book with text and diagrams, but every reader sees it in the format he or she most easily understands. Wanda Vision's Darkhold is more archaic and ornate, written in some sort of ancient language.

It's not clear which one, but if you grew up in colonial New England, it's probably not the language you're most familiar with.

But more to the point, these books are not the same subject. However, they are treated and behave in the same way as the dark hold of comics. In other words, either there are two darkholds in the MCU, or these two programs are not in the same universe.

In the comics, Darkhold was written by the elder god Kuton (think Cthulhu, but worse) and served to convey his power on Earth. In other words, Darkhold was a one-of-a-kind item, not a substitute that could be taken to a printing house and reproduced.

The continuity between Marvel TV and Marvel Studios has always been a point of contention, even though Agents of SHIELD has always done its best to incorporate movie stories into its own plots. At least that was the case until the show's sixth season arrived and completely ignored the fact that Thanos had taken half of all life.

Despite sharing the name Marvel, Marvel Television and Marvel Studios are separate companies. Marvel Studios has been part of Disney's film division since 2015, while Marvel TV is part of Marvel Entertainment, a company that is responsible for toys, comics, and everything else related to the Marvel universe.

There is some bad blood in this relationship, but that's a story for another time. Needless to say, Marvel Studios has largely ignored MCU-centric television programming for several years. The only exception was James D'Arcy's brief cameo in "Avengers: Endgame," reprising his role from "Agent Carter" as Howard Stark's butler Jarvis.

Some fans have attempted to reconcile this connection, and in the absence of evidence to the contrary, Marvel TV still maintains that it is canonical in the MCU. Until the casual appearance of Darkhold in Wander Vision.

With a wave of her hand and a seemingly inconsequential line, Agatha has erased most of Marvel TV from the MCU canon. At least "Agents of S.H." is. I.E.L.D." and its related spin-offs "Inhumans" and "Runaways. Perhaps "Cloak and Dagger" as well, since it crossed over with "Runaways" a while back.

With other prominent agents from the "S.H.I.E.L.D." series, there is more reason to suspect a casual breakup of the show: while MCU movie characters Clark Gregg and Maria Hill (among others) appeared in the TV series, none of the show's characters made it to the movies. And now that the show's major relics have been reconfigured to look completely different, it is not hard to see how these Marvel shows might not have happened in the MCU.

What is certain is what will happen to the rest: the Netflix Marvel shows ("Daredevil," "Jessica Jones," etc.) are still in limbo, as they have only crossed over with each other. Similarly, the status of "Agent Carter" is still unknown, but Jarvis' appearance in "Endgame" suggests that some version of this show has happened in-universe.

However, "Agents of SHIELD" lasted seven seasons, making it the longest-running Marvel TV show of the modern era. And now we actually have concrete evidence that it was erased from canonical history. It turns out that it was Agatha all along.
