Since WandaVision's series finale on March 5th, the only content more pervasive throughout the fandom than plot hole debates is speculation over a second season.
Curiosity over a show's renewal status is common, despite studios usually greenlighting additional season(s) publicly before the prior ends. When such an announcement doesn't come, you can expect plenty of internet speculation and clickbait fueled by the desperate hope of mourning fans. Will Fleabag come back for a third season? The End Of The F***ing World was too good not to keep going, right?
What makes WandaVision Season 2 speculation unique is that it exists in spite of the show itself — with episode names, themes, timelines, and character set-ups spelling out the fact that it's completely finished. The most obvious example of this is, of course, the final episode: "Episode 9: The Series Finale."
It's as if audiences, after weeks of trying to unravel the mysteries of WandaVision and the fictional town of WestView, have become conditioned to distrust appearances. Surely the title of the final episode was a meta ploy by Marvel, hinting that we're all under Wanda's spell to believe she closed the hex and the series is finished. Or maybe it's Agatha's spell! She's too powerful to have been trapped by Wanda in the sunken place (New Jersey).
