Why Agatha wasn’t in VisionQuest, according to the showrunner

VisionQuest showrunner Terry Matalas joked that Marvel couldn’t afford Kathryn Hahn. The real reason Agatha skipped the finale comes down to Billy, and her ghost could still return.

Marvel fans spent all of VisionQuest waiting for Agatha Harkness to show up. She never did.

Now the showrunner has explained why. In an interview with ScreenRant this month, VisionQuest showrunner Terry Matalas opened with a joke: “We can’t afford Kathryn Hahn!”

Then he gave the real answer.

Why didn’t Agatha Harkness appear in VisionQuest?

Matalas said Hahn simply takes over any scene she walks into. “The second you bring Kathryn Hahn into a scene, it’s a Kathryn Hahn scene,” he told ScreenRant.

That was a problem for the big emotional moment the show was building toward. Joe Locke returned as Billy, one of Wanda and Vision’s sons, for a reunion that needed to stay focused on him.

Matalas said the scene had to be about Billy, and adding Agatha just because it would be fun to see her would pull away from the story.

So Agatha stayed on the bench.

It is a fair call, even if fans wanted more. Hahn’s Agatha was the breakout character of WandaVision, and her song “Agatha All Along” became a viral hit. Any scene with her in it would have turned into an Agatha scene, which is exactly Matalas’ point.

What happened to Agatha at the end of Agatha All Along?

Agatha All Along, the second show in what fans now call the WandaVision trilogy, ended with Agatha giving up her physical form to save Billy.

She did not stay gone for long. She came right back as a ghost and promised to mentor Billy as he learned to control his powers and searched for his brother.

That setup is why so many fans expected her in VisionQuest. A ghost mentor only Billy can see feels made for a surprise cameo.

Will Kathryn Hahn return as Agatha in the MCU?

The door is open. Matalas told ScreenRant that, down the line, it would be fun to see what is going on inside Billy’s head with his “imaginary friend” Agatha. He said the show leaned into that idea with Billy talking to her in one moment.

Hahn wants back in, too. After her Golden Globe nomination for Agatha All Along, she told Deadline in 2024 that everyone would be thrilled to come back in any capacity.

She said it again this summer. In August 2026, she told Access Hollywood she has no idea what is next, “but I sure would love it.”

Is VisionQuest the end of the WandaVision story?

For now, it closes out the story that began with WandaVision in 2021. TVLine called the VisionQuest finale the end of the trilogy, and it gave fans some long-awaited closure on Wanda and Vision’s family.

That does not mean the characters are done. Marvel loves bringing back fan favorites in surprising places, and the studio has the next Avengers movie, Avengers: Doomsday, arriving Dec. 18.

Where can you watch VisionQuest, WandaVision and Agatha All Along?

All three shows are streaming on Disney+. WandaVision started the story in 2021, Agatha All Along followed in 2024, and VisionQuest just wrapped its finale this week.

If you missed Agatha’s big exit, the last episodes of Agatha All Along are worth a rewatch before you start VisionQuest. It makes Billy’s story land a lot harder.

And yes, the “Ballad of the Witches’ Road” will absolutely get stuck in your head again.
