Marvel's VisionQuest Ending Explained: Will Vision And Ultron Return?

This article features spoilers for the series finale of VisionQuest

Marvel Studios have increasingly focused on stand-alone series in recent years, after the underperformance of several shows and movies has led to scaling back on just how interconnected this universe stands. "VisionQuest" only required knowledge of "WandaVision" and "Agatha All Along," forming the last entry in a miniseries trilogy, but the final moments still left us with questions about how it will affect the wider universe.

Vision's (Paul Bettany) story reached an emotional yet optimistic conclusion, but he didn't defeat Ultron (James Spader) so much as ever-so-slightly reign him in. Any suggestion that he's going to settle down for a quiet family life may prove short-lived, although with none of the cast currently confirmed to return in any upcoming MCU project, should we see this as a definitive ending, even when there are signs of trouble brewing that could prove every bit as apocalyptic as Doctor Doom's plans?

Below, we've broken down the finale of VisionQuest, how the mid-credits scene sees the return of one of the franchise's biggest villains, and whether this is a goodbye to Vision or just a temporary farewell. Plenty of spoilers follow, so if you didn't read the disclaimer above, consider yourself warned again ...

Call it a case of "Eternal Sunshine of the Artificial Mind," as we discover scientist Virgil Horton (Spader) resurrected his wife Josephine "Jo" Carrington (T'Nia Miller) but felt buyer's remorse because he'd recreated her emotional headspace too well. He removed all traces of himself from her synthetic headspace and hired Paladin (Todd Stashwick) to locate Vision in the hope of putting Ultron -– modelled after himself -– into his body, so she'd have a new partner worthy of being with a "Goddess." That naive plan was admittedly compromised by his next step, which was the two ruling over humanity with 20 billion nanobots patrolling Earth and keeping mankind compliant.

Jo is not willing to go along with, and luckily just as Vision is ready to have his mind replaced, son Tommy (Ruaridh Mollica) shows up with the super speed powers he inherited from his uncle. Jo and Vision work together to destroy Virgil's quantum processors that are deleting Vision's identity, but Virgil shoots her in the process, angering Ultron, who immediately kills him in response.

Ultron follows through with sending a nanobot swarm to London, and Vision counters it the only way he knows how; placing him in a simulated sitcom called "UltraVision." He succeeds at the last moment, triggering Ultron to self-destruct the nano swarm, but Vision perishes along with it. Luckily, other son Billy (Joe Locke) appears through a portal to magic him back to life. Vision closes the doors to his Mind Castle to start a proper family, and finally, spares Ultron's life believing he deserves a second chance.

The revelation of who Ultron's human avatar was designed after lingered throughout the season, and the finale neatly ties things together, revealing him to be Virgil Horton, son of Dr. Phineas Horton. Referenced earlier as the "grandfather of robotics" who created the ill-fated synthetic man — whose source code paved the way for all this universe's future AI –- the elder Horton has long been referenced as far back as 2011's "Captain America: The First Avenger."

There, Steve and Bucky saw a prototype for his synthetic man on display at the Stark Expo, hinting at the introduction of Phineas further down the line. He dubbed his creation the Human Torch, and in the comics, got furious at the Fantastic Four for stealing that moniker, making him more determined to revive that creation. However, he'd get kidnapped and killed by Ultron, who wanted him to reprogram his creation to assist with his evil plans.

"VisionQuest" channels this narrative through the introduction of son Virgil Horton, who has a lifelong chip on his shoulder because of his dad's reputation. Along with his wife Jo, Virgil sought to rehabilitate the family name from a scientific laughingstock and complete his father's work, eventually bringing back his company from Stark Industries in return for taking on an analyst job at S.W.O.R.D, where he could continue his AI experiments.

Interestingly, the resurrected AI Jo compliments the character's original comics characterization, where she was designed as a partner for Ultron. She quickly became an Avenger, however, mirroring her screen counterpart's awakened conscience when faced with his evil plans.

Just before the end credits, Ultron calls Vision as he's leaving his Mindspace. He knew he was still alive because too many nanobots were unaccounted for, but didn't say anything because he believes even supervillains deserve second chances. Asked what he'll do with his free time, he says he'll either go to the Louvre or burn all of mankind to ash -– a coin flip on whether he'll choose good or evil, but a choice he doesn't want to do alone regardless. It's this ambiguity that the brief mid-credits scene thrives upon.

Picking up with a freshly shaven Ultron, we see him holding a device which contains the consciousness of Jocasta, aka Josephine Carrington. No words are spoken, but he's clearly pondering resurrecting her again, whether it's for good or for ill. Considering that the character becomes an ally to the Avengers when resurrected in the comics, and how quickly she aided Vision at risk of death here, it's safe to assume that if Ultron is planning on taking over the world again, he'd know better than to bring her by his side. But then, he did kill Virgil and is still grieving, so another ill-fated revenge mission isn't out of the question.

More realistically, however, Spader and Miller haven't been announced for any future MCU projects, so this will probably not have any drastic consequences for now. He really might just want someone to go to Paris with.

After leaving the mansion, we pick up an unspecified amount of time later, as Paladin, Tommy's girlfriend Lisa (Lauren Morais), and Tommy himself board the bounty hunter's private jet, after he's reluctantly agreed to give them a ride to New Jersey to meet his brother properly. Paladin is reforming his operations with the help of Emily Hampshire's E.D.I.T.H, who he's now in constant contact with via special augmented reality glasses; she's redesigned his logo to something cuddlier against his will and wants him to consider only taking "ethical" jobs (although nothing pro bono, God forbid).

In the middle of this, Tommy puts on his own specially designed augmented reality glasses to speak with his father in his Mindspace ahead of closing it down. Vision is still in Edinburgh, and is closing down the "nest" in his head to dedicate more time to his sons, stating that rebuilding that relationship was the "best thing that's ever happened" to him. It's assumed Vision's physical avatar will cross the Atlantic to reunite with his sons and start something approaching a normal family life; he's now well-versed in human emotion enough to know that there's no old-fashioned sitcom waiting for them.

It's an optimistic ending, with Vision retreating from his head and looking outward to the future. But there is one elephant in the room that doesn't go unaddressed.

In 2022's "Doctor Strange in the Multiverse of Madness," it appeared that Wanda (Elizabeth Olsen) had been killed for good, sacrificing herself by destroying every copy of the Darkhold, which caused Mount Wundagore to collapse onto her. Her dead body was never shown, but the fact Agatha Harkness (Kathryn Hahn) was freed from the spell Wanda had previously cast on her at the start of 2024's "Agatha All Along" wasn't the optimistic sign fans were hoping for. The "VisionQuest" season premiere reinforced her fate with Vision stressing that she was "crushed under the weight of a mountain."

In the final moments of Episode 8, Tommy asks Vision whether it was possible to see his mother again; after all, neither he nor his brother should exist, and their father is a sentient robot, so it's not the most far-fetched proposition. Vision is optimistic but non-committal, stressing that although they've said goodbye before, he supposes "it stands to reason they say hello again." And this likely reflects Olsen's real-world position, with the actress previously stressing she'd love to return if offered a meaningful story arc.

The door is open to bring her character back, but unless she's deliberately lying to avoid leaking a future cameo elsewhere (reports suggest Doom's Latverian Witches will appear in "Doomsday," and we know a more powerful witch who could join them), it seems that she won't return. A cameo in "VisionQuest" was always going to be off the table.
