Marvel Studios is about ready to unleash VisionQuest on the world. The long-awaited third entry in the WandaVision Trilogy, it brings back Marvel veteran Paul Bettany as the beloved synthezoid Vision - who we haven't seen in almost six years. That's the beauty of the Marvel Cinematic Universe; characters can show up at any given time, even years after their previous appearance. But there's a reason that Vision has been off-screen for so long. And that's what the spinoff is here to explore.
VisionQuest is technically a sequel series to WandaVision, with Bettany back in a leading role. However, it's also a sequel to the first WandaVision spinoff Agatha All Along, starring Kathryn Hahn as the ancient witch Agatha Harkness, who Wanda and Vision encountered during their stint in Westview. Both of those shows were created and brought to life by Jac Schaeffer, who is loosely involved in VisionQuest too (Terry Matalas took over as showrunner when she had to depart the project).

As VisionQuest is the third and final chapter in that ground-breaking trilogy, fans have one question: Do I need to watch Agatha All Along before VisionQuest? It's a complicated answer, but the long and the short of it is that, yes, you should. Although the upcoming Disney Plus series is a direct sequel to WandaVision, bringing back one of its main characters, its entire plot revolves around something that was only made possible because of Agatha - and that's somewhat hard to explain to someone who hasn't seen it.
The crux of VisionQuest is that the White Vision, with his memories restored by the Hex Vision in WandaVision, is having trouble connecting with those memories. They are like files to him; files that he didn't actually live through and therefore has no emotional attachment to. With the AIs of the MCU - including the villainous Ultron (once again played by James Spader), Vision tracks down his son Tommy Shepard, a.k.a. Tommy Maximoff, in a bid to reconnect with his emotions. Having previously thought that his son was fictional, a conjuring of Wanda's Hex, Vision now has a chance to rediscover his feelings and help his son in the process.
But, if you haven't been keeping up with the MCU, you might find it odd that Vision's son is even alive. Because, yes, he and his twin brother Billy were indeed conjurings of Wanda's Hex in Westview. So how could they be real? That's where Agatha All Along comes in. After all, magic is at the heart of this trilogy, so - despite VisionQuest's focus on technology - it's important to understand how that magic ultimately brings this trilogy to a close.
Furthermore, Agatha All Along is easily one of the most creative, awe-inspiring, and clever shows that Marvel Studios has produced for the Disney Plus streaming service. While the Multiverse Saga has been admittedly pretty muddled in terms of quality, Agatha was a real surprise upon its release, earning critical acclaim for its innivative storytelling, genuine use of the television format, and incredible ablity to subvert expectations. Kathryn Hahn also proves that she is one of the MCU's best casting decisions of all time, offering up a thrilling performance as the mischevious witch at the center of the WandaVision Trilogy.

While both Wanda Maximoff and Vision were characters in the MCU long before WandaVision made its presence felt on Disney Plus in 2021, it is the project that set all of this madness in motion. Both Agatha's journey in Agatha All Along and Vision's journey in VisionQuest are set in motion due to Wanda's actions in Westview in this original series. And it's absolutely worth revisiting in order to fully understand the emotional journey that Vision undergoes in his upcoming spinoff.
The critically-acclaimed sitcom-turned-drama is largely considered Marvel TV's greatest accomplishment, earning 23 Emmy nominations and showing us all what Marvel Studios was capable of with the small screen at its disposal - and it set a high standard so high that the Multiverse Saga has rarely matched it ever since.
The question isn't if you should be rewatching it, it's when shouldn't you be watching it?! It's always a good time to revisit this gem.
Avengers: Age of Ultron is a reminder of how it all began for Vision and Ultron
Where to stream: Disney Plus
If you would like to go way back to the beginning of Vision and Ultron's MCU journeys ahead of VisionQuest, then you should definitely take the time to check out Avengers: Age of Ultron too. Although it was regarded as the weakest Avengers movie throughout the days of the Infinity Saga (it is the most standalone of the four), the years have been kind to it, in no small part thanks to its influence on the WandaVision Trilogy.
Earth's Mightiest Heroes must unite when Tony Stark's attempts to create a protective shield around the Earth named Ultron backfire, with the AI consuming JARVIS, taking control of the internet in seconds, and locking the Avengers out. This ultimately leads to the creation of Vision, who does battle with the all-powerful robot in a bid to save Earth from its doom. And, in doing so, he always crosses paths with Wanda Maximoff and her twin brother Pietro for the first time.
James Spader's return as Ultron makes Avengers: Age of Ultron a must-watch. The fact that it just so happens to feature the debuts of Vision and the Scarlet Witch is a bonus that should send it over the finish line. If you have time before VisionQuest, revisit the ancient texts!
VisionQuest arrives on Disney Plus on October 13, 2026.
