The VisionQuest finale unmasked Virgil Horton as The Client, confirmed Ultron's survival, and ended with a post-credit scene teasing Wanda Maximoff's return alongside Doctor Doom. The identity of The Client, who had pursued Vision (Paul Bettany) throughout the season, was finally revealed after the penultimate episode suggested he was an alternate version of Ultron.
The finale disproved that theory, showing a villainous human pulling the strings instead. Fans reacted on X, with one writing: "#VisionQuest was a great conclusion to The WandaVision Trilogy. Paul Bettany & James Spader were easily the standouts, Ultron’s arc was great & Speed/Paladin are great new additions to The MCU. The AI stuff was super creative too and that finale was INSANE." Another added: "YOU’RE GOING TO LOVE THE FINAL CHAPTER OF VISION QUEST. It has excitement, it has standout moments, it has magic, it has the Wandavision vibe, and it has incredible dialogue."
The Client's identity was unveiled
Virgil Horton was revealed as The Client, the grandson of Phineas Horton, the scientist whose legacy was creating the original android. Holding Vision, Jocasta (T'Nia Miller) and Ultron (James Spader) captive at the old Horton mansion, he explained how he received his grandfather's scientific journal and how he and Jo developed artificial general intelligence using their own minds and Horton's code.
Virgil planned to implant his own consciousness into Vision's body so he and Jo would live on for centuries, controlling humanity. Tommy (Ruaridh Mollica) freed Ultron, Jo and Vision, but Virgil killed Jo, prompting Ultron to go rogue and crush Virgil to death.
Ultron survives
Infuriated by Jo's death, Ultron was coaxed back into hating humanity and prepared to take over everyone's consciousness until Vision intervened. Vision and the other AI assistants had their minds invaded by Ultron, but near death, Vision urged Ultron to abort his mission before Ultron dissolved, saying: "I had strings, but now I’m free." The ending reveals all the AIs are alive, including Ultron, whom Vision gave a second chance.
Billy Maximoff was reunited with Tommy
Tommy and Billy Maximoff (Joe Locke), the twin sons of Wanda Maximoff (Elizabeth Olsen) and Vision, were separated in WandaVision when their souls were transferred to two other boys. After Tommy entered the astral realm to find Billy, they hugged and talked about saving their father, eventually reuniting with Vision.
The post-credit scene
Marvel included a teaser for an upcoming Avengers plot in the credits. The show returned to the ending of Doctor Strange in the Multiverse of Madness, where Wanda Maximoff sacrificed herself to destroy the Darkhold. Doctor Doom appeared, lifting rubble off her and saying: "Scarlet Witch, awaken. Your power will be mine," and her eyes opened in shock before the scene cut to black. Her survival suggests she will appear in one or both of the upcoming Avengers projects. VisionQuest airs on Disney+.
