WandaVision left us with a few unanswered questions, including why Wanda Maximoff's sitcom reality was being broadcast outside the Hex. Dr. Darcy Lewis mentioned that someone was editing them, and that was a big part of the reason why many fans theorised that a secret villain had to be pulling the strings (like Nightmare or Mephisto).
In an interview with Rolling Stone, WandaVision Head Writer Jac Schaeffer finally elaborated on the plot point, explaining why the Scarlet Witch chose to share her new reality with the outside world.
"In my mind, Wanda is broadcasting for two reasons. One, she’s curating her experience. She is creating the full picture of her idealized world. So she’s editing and adding a score and adding commercials, and she’s making the completed piece that is verification of her perfect life."
"Second to that, I think she’s looking for a witness. It’s a call for help. It’s reaching out," the writer continued. "The broadcast ends and cuts out after the hex expansion at the end of Episode Seven. And that’s because she’s done with the outside world."
This is a fascinating insight into Wanda's mindset in the Disney+ series, and it's a shame a little more time wasn't devoted to what many fans ultimately felt was an unresolved plot point.
Despite that, WandaVision did a great job of exploring the Scarlet Witch's damaged psyche, and nicely set the stage for her story to continue in Doctor Strange in the Multiverse of Madness. There, Wanda is likely to tear her way through the Marvel Cinematic Universe's version of the Multiverse in a bid to find Tommy and Billy, whose voices she heard while exploring the Darkhold in that post-credits scene.
Doctor Strange in the Multiverse of Madness is set to be released in theaters on March 25, 2022.
