Elizabeth Olsen as Wanda Maximoff in WandaVision Marvel Studios

In 'WandaVision,' Elizabeth Olsen has already explained what is going on.

Elizabeth Olsen, star of "WandaVision" five years ago, sent us a reading list to help plan for the Disney+ series almost five years ago. We just didn't realize it then.

Olsen says in a video taken for an Allure cover story in 2016, "I'm about to tell you the history of my Marvel heroine, the Scarlet Witch." She then provides a brief summary of several main comic book stories that have "WandaVision" aspects that are obviously inspired.

She passes through the comic book landmarks of the Scarlet Witch, including meeting the Vision, falling in love, getting married and doing all the "lovey dovey stuff that happens between a mutant and the robot of her dreams," all the way back to her character's first appearance and beginnings as a villain.

This entails using spells to activate her own "Marvel immaculate conception" and giving birth to twin boys.

While carrying a hexagon-shaped prop, Olsen notes that the powers of Wanda Maximoff have the capacity to generate "chaos that disrupts reality." Helpfully listing individual comic book runs, she also goes through the numerous tragedies that lead to the ultimate emotional collapse of the Scarlet Witch. "She will also name-check Doctor Strange, played by Benedict Cumberbatch, who will join the forthcoming "Doctor Strange in the Madness Multiverse.

Of note, "WandaVision" is not a direct translation of any actual comic book storyline, like other names in the Marvel Cinematic Universe. And the new announcement from the show that Agatha has been a hidden player in the sitcom world of Wanda all the time makes it clear that "WandaVision" already has a lot of surprises to unfold in its remaining two episodes.

But the books Olsen lists in the video may be a decent place to start for those concerned with searching up more clues on where the show could be going.
