Agatha Harkness did not make an appearance in the final episode of VisionQuest, and fans have been wondering why she was not brought back for a cameo.
The recent MCU show's finale featured appearances of returning characters from previous installments in the WandaVision trilogy, which delighted fans as it teased a promising future for them, as well as their potential return in the upcoming Avengers: Doomsday.
However, Agatha Harkness was absent, despite being a pivotal character in the previous shows. Fans were hoping that she would have a cameo appearance in VisionQuest, but alas, it did not happen, nor was she even explicitly mentioned.

Why Agatha Harkness Did Not Return in VisionQuest?
In an interview with Collider, VisionQuest showrunner Terry Matalas explained why Agatha Harkness did not have an on-screen appearance in the final episode, despite also bringing back Billy Maximoff.
He cited budgetary reasons as the main factor in why Kathryn Hahn was not brought back to reprise the role of her character in ghost form. He also wanted the scene to focus more on Tommy and Billy's reunion.
"I don't know that we could have afforded that. [laughs] So not really, no. We always knew that reunion was going to be, and how much of it, and how early — what would be right for Tommy, what would be right for Billy, what would be right for the family story," Matalas said.
"But I feel like we got the proper emotional reunion for them. And I think the way that his return impacts Vision — without being too spoilerific — is important."
While Agatha did not physically show up, we can still see Billy talking to her off-screen during his reunion scene with Tommy, indicating that the fan-favorite witch is still in her ghost form in the events of VisionQuest.
Hopefully, Marvel has concrete plans to bring back Agatha Harkness in a future project, considering that there is strong demand from fans to see more of her in the MCU.
What Is VisionQuest About?
