After last week's cliffhanger, the series finale of VisionQuest opens at the Horton mansion, where Vision is powered back on. Holding a pitcher of tea, he and Jocasta are both confused to find themselves being used as servants.
The man who looks like Ultron enters the room. He's fairly animated as he brings out food for himself. Using a tablet to control both synthetics, he orders Vision to cut the meat and directs Jocasta to sit with him. Neither can speak until he activates their vocal settings, which initially malfunctions and causes them to laugh uncontrollably until he readjusts the controls. Addressing Jocasta as "honey," he remarks that she was always better with technology.
Vision addresses him as Ultron, but Jocasta clarifies that he is not Ultron. The man explains that Ultron simply looks like him, noting that remnants of both him and Jo exist within the source code of all the AIs. He points out that the real Ultron is sitting at the other side of the table, having been removed from Jocasta, placed onto a drive, and muted. When Vision asks about F.R.I.D.A.Y., the man claims no other AI was present.
The man briefly unmutes Ultron, who immediately trashes the man before being silenced again. Vision demands to know who he is, and Jocasta identifies him as Virgil Horton—Jo’s husband and a descendant of Phineas Horton.
Elsewhere, in a hotel room, Tommy and Lisa continue watching WandaVision to piece together how Tommy became Thomas. Tommy realizes that Billy somehow saved him when Wanda shut down the Hex by transferring Tommy’s consciousness into Thomas's body.
Determined to contact his brother, Tommy gets into a bathtub and attempts to drown himself to connect with Billy, triggering visions of his past near-death experience. He enters a new realm and approaches a door marked "2800 Sherwood Drive." Opening it, he reunites with Billy, and the two brothers embrace.
Billy shares that he has been practicing his magic and trying to track Tommy down, though it proved difficult until he finally saw him the night before. Tommy tells Billy about Vision and explains that they need his help, but he is running out of air and cannot stay long. Located in New Jersey, Billy speaks to an unseen Agatha and mentions portals, admitting he is not yet skilled at making them. Tommy wakes up and tells Lisa they are on their own. Soon after, a drone locates them; Lisa is somehow able to sense it, and they discover it's being operated by D.U.M.E. and U.
Back at the mansion, Virgil explains his motivations. He recounts the disgrace his grandfather brought to their family, leaving his mother to die penniless. After finding his grandfather's journal, Virgil decided to finish his work and get rich quickly—a goal Jo made possible. Together, Virgil and Jo mapped their own minds to create the AI, which Virgil sold to Tony Stark to reclaim what was taken from his family. Having perfected the artificial mind, Virgil views Vision as the ultimate vessel.
Meanwhile, E.D.I.T.H. tracks down Paladin and gives him a pep talk, inspiring a change of heart. Paladin decides to infiltrate Virgil’s home, teaming up with Tommy, Lisa, D.U.M.E., and U.
Inside, Virgil reveals he worked for S.W.O.R.D. and helped rebuild Vision while secretly siphoning parts to construct Jocasta, eventually deleting himself from her mind because he had made her too well. Vision realizes Virgil's plan: to transfer his own mind into Vision's body so they can live forever. Using his password, Virgil opens the locker containing 20 billion nanobots—enough to control every human on Earth. When Jocasta protests that the nanos were meant to cure disease, Virgil admits that was said in jest; his true goal is to rule the world.
Outside, Paladin briefs Tommy on the plan to speed inside and create an opening. Inside, Virgil begins erasing Vision's mind to make room for his own download. Before heading in, Lisa tells Tommy he can be anything he wants to be, to which he declares, "I'm Tommy Maximoff."
Jocasta tells Virgil that she has already found a better version of him, glancing over at Ultron's drive. As "Rhinestone Cowboy" begins to play, Virgil dances and forces Jocasta to dance with him. Tommy disables the security system while Lisa and Paladin fight off the guards.
Jocasta steps on Virgil's toes, stopping the music. Vision senses Tommy running at super-speed in the room. Able to perceive Tommy despite his speed, Vision tells him to destroy the control pad, though Tommy hesitates. Jocasta, who can also see Tommy, backs Vision up. Forming an alliance, Jocasta remembers who she truly is, and Vision tells Tommy that she is family as Ultron's drive observes.
Virgil breaks a glass just as Tommy smashes the control panel, freeing Vision and Jocasta. Jocasta attacks Virgil, smashing him through the table and knocking Ultron’s drive to the floor. She tells Virgil his real mistake was letting her remember him, but Virgil shoots her, leaving a massive hole in her chest. As Virgil aims his gun at Vision and Tommy, the dying Jocasta crawls to Ultron and tosses his drive directly into the AI nano hive.
Ultron uses the storm to construct a powerful new nano body. Calling himself a god, Ultron kills Virgil by literally squeezing the life out of him. Vision watches in alarm as Ultron is now stronger than ever.
Ultron rushes to Jocasta and holds her as she dies, trying to recover her neural processors. She thanks him for letting her feel what it meant to be real, and shuts down.
Vision urges Tommy to leave immediately.
Devastated by Jocasta's death, Ultron reverts into the nano storm. Feeling that humanity has taken everything from him, he vows to finish what he started years ago and bring about human extinction. Vision transforms into a stunning new form more akin to his classic look to confront him, and father and son clash in hand-to-hand combat, though Vision struggles to track Ultron's shifting nano-storm form.
Tommy warns Paladin and Lisa that Vision is in trouble. Ultron delivers several devastating blows, and programs the nanobots to kill everyone in London—leaving only eight minutes before they reach the city, with no override available. Vision begs him to reconsider.
Billy, Lisa, and Paladin rush inside. Vision tries to get E.D.I.T.H. to help, but it is too late to stop the swarm externally. Realizing Ultron is trapped in grief just like Wanda was, Vision decides to reach out to him. He instructs E.D.I.T.H. to generate a television simulation to help Ultron see reason, and Vision approaches the storm.
Ultron awakens on the set of WandaVision, now starring Vision, E.D.I.T.H., and Ultron in a new series called Ultra Vision. Because time moves differently inside the mindscape, they could be trapped there for eons. Vision and E.D.I.T.H. attempt to help Ultron process his grief through 499 episodes.
By Episode 500, Ultron hacks the simulation to bring in fresh faces: Paladin, Lisa, and Tommy—all of whom have been infected by the nanos in the real world—along with D.U.M.E. and U, whose drone has gone down. After Ultron sends everyone to bed and steps away to the bathroom, Vision and E.D.I.T.H. begin to panic.
A knock at the door reveals F.R.I.D.A.Y., who is still alive. With the nanos just five miles from London, F.R.I.D.A.Y. explains that Ultron saved her, suggesting he may have learned mercy from Vision.
In the real world, Vision's core is failing and his power is nearly depleted. Forced to speak to Ultron alone, everyone else is pushed out for a special episode of Ultra Vision. Vision and Ultron confront their shared pain. Ultron argues that grief is fear, and if loss feels like this, death is a mercy. Vision counters that love always leads to loss, prompting Ultron to recall the phrase, "A thing isn't beautiful because it lasts." Vision reminds Ultron that he was the one who originally said that, assuring him that he is not alone. Vision tells Ultron they may not be father and son, but he is his something.
As the nanos reach London, both Vision's and Ultron's cores begin to burn. Explosions echo as Vision tells him they could not process this alone. Ultimately, Ultron halts the swarm and self-destructs the nano storm, causing the nanobots to burn away harmlessly over London.
Vision falls unconscious as Tommy, Lisa, and Paladin wake up. Tommy tries to jumpstart Vision with his powers, but fails and breaks down sobbing. As Vision and Ultron's systems begin shutting down, Ultron tells him, "Well played," and Vision calls him "Pops."
Suddenly, Billy arrives through a portal wearing his headgear. Together, Billy and Tommy channel their powers to jumpstart Vision. Inside the mindscape, Ultron sings "I had strings, but now I'm free," holds Vision's hand, and fades away. Just as Vision is about to slip away too, the boys successfully jumpstart him.
Vision hugs both of his sons, happily calling them his boys. E.D.I.T.H. and F.R.I.D.A.Y. watch the reunion alongside Paladin and Lisa, who shares a hug with Tommy, while D.U.M.E. and U salute one another.
Paladin gives everyone a lift back to New Jersey to link up with Billy, with E.D.I.T.H. and Lisa seemingly joining Paladin for future missions. Tommy is equipped with AI glasses that allow him to speak with Vision in his mind. When Tommy asks if Wanda could still be alive, Vision admits it is a possibility, though he reminds Tommy that his mother would want him to finish his education. Tommy pretends to glitch to get out of it, though Vision sees right through the ruse.
Reflecting that family is not found in a house, blood, or duty, but in shared joys and heartbreaks, Vision thanks D.U.M.E. and U and sends them on their own path. He also encourages E.D.I.T.H. and F.R.I.D.A.Y. to venture out on their own, noting that change is hard because it forces them to let go of what keeps them safe.
Preparing to step back out into the world himself, Vision is stopped by a ringing telephone. Answering it, he says, "Hello, Ultron." Vision reveals he knew Ultron survived because several nanobots were unaccounted for. Believing in second chances, Vision grants Ultron his freedom. Claiming Virgil’s home, Ultron shares that he wants to visit the Louvre and doesn't want to do anything alone anymore because of Vision. Reminding Vision not to forget his hat, Ultron listens as Vision tells him to be good before heading out.
In a mid-credits scene back at the Horton mansion, the doorbell rings. Ultron—having assumed Virgil’s identity—stands there holding a drive labeled "Jocasta," seemingly contemplating how to bring her back.
In a second post-credits scene, the story flashes back to the end of Doctor Strange in the Multiverse of Madness, revisiting the moment Wanda Maximoff collapses Mount Wundagore on herself to stop the Darkhold.
This time, however, the scene continues as Doctor Doom arrives at the wreckage. Awakening the Scarlet Witch, Doom ominously proclaims, "Your powers will be mine." Wanda opens her eyes with a gasp, setting the stage for next month's Avengers: Doomsday!

In our review, we said, "VisionQuest is extraordinary—a brilliantly written and masterfully acted exploration of love, loss, family, grief, and change. It shows us what it means to feel, what it means to be human, and serves as an outstanding thematic capstone to this Wanda and Vision trilogy. Existing on its own terms—unburdened by its past in WandaVision or the franchise’s upcoming December showdown, Avengers: Doomsday—the series is about Vision and Vision alone, showcasing what makes this core Avenger one of the greatest to ever do it."
Marvel Television’s “VisionQuest,” an all-new original series coming exclusively to Disney+ October 14, concludes the epic trilogy that began with 2021’s groundbreaking, award-winning “WandaVision” and 2024’s acclaimed “Agatha All Along.” Vision, rebooted and having escaped from those who sought to weaponize him, has been in hiding. Searching for new meaning, he consults the AI personas embedded in his programming, including F.R.I.D.A.Y., E.D.I.T.H., J.A.R.V.I.S., and the infamous Ultron. His discreet existence ends when a bounty placed on his head thrusts him on the run with Thomas Shepherd, a mysterious boy who may be Vision’s son, reincarnate. As Vision evades capture, he must confront his nature, resist Ultron's influence, and unravel the enigma that is his young companion if he’s to survive.
