VisionQuest has dropped its eighth episode on Disney+, and the action-packed finale has given followers of the Marvel Cinematic Universe plenty to talk about.
The hit series follows the Avenging android Vision (Paul Bettany) as he attempts to restore memories lost from his run-in with Thanos and a slap-dash reconstruction by SWORD.
Along the way, he becomes reacquainted with his long-lost son Tommy (Ruaridh Mollica) and clashes with his father of-sorts Ultron (James Spader).
In a nod to Marvel's comic book lore, the latter has been on a journey of his own, including his first experience of love with a similarly devious AI known as Jocasta (T'Nia Miller).
Her plan to subjugate humanity using invasive nanobots was exposed in VisionQuest's penultimate episode, but the plot was halted by a last-minute intervention.
The mystery figure who hired bounty hunter Paladin (Todd Stashwick) is finally ready to reveal themselves, and it happens to be... James Spader? Huh.
Here's everything you need to know about the VisionQuest ending, as the final episode arrives on Disney+.

VisionQuest ends with a stand-off between Vision and his sort-of father (or at least, his "something") Ultron, which brings this Disney+ trilogy full circle.
Just as it began with Wanda Maximoff (Elizabeth Olsen) turning her life into a classic TV comedy through the power of magic, it ends with Vision trapping his own grief-stricken rival in an AI-generated sitcom.
But first, we finally get a formal introduction to the architect of Vision's misery, who has been teased for weeks as a distorted silhouette.
No, it isn't an unannounced returnee from the wider MCU – hopes for Sharon Carter (Emily VanCamp) found dashed – but rather, the new character of Virgil Horton (played by Ultron actor James Spader).
As was the case with JARVIS (James D'Arcy), FRIDAY (Orla Brady) and EDITH (Emily Hampshire), even Ultron has a human counterpart from which he was derived. Unsurprisingly, they don't get along.
Virgil is the grandson of Phineas Horton (memorably played by Paul Bettany in episode 7), who pioneered AI development in the MCU through his defective 'Jim Hammond'.
The eccentric Virgil recounts how he had continued his grandfather's work, which brought him into contact – and later, romance – with Jo Carrington (T'Nia Miller).
Their dalliance ended in disaster, however, when he betrayed her by selling their work to Stark Industries; at the time, still a weapons manufacturer of low regard.
In the days leading up to her death from a terminal illness, Jo had replicated her consciousness as an AI, but it wasn't until years later that she regained a physical form.
A grieving Virgil had built her formidable metal body by siphoning materials away from Vision's reconstruction, during a stint working at high-tech government agency SWORD.
Just as he betrayed Jo in life, Virgil continues to be an unworthy partner, as shown by his humiliating display of dominance over Jocasta, in which he forces her to dance with him.
The immobilised Vision and Jocasta are eventually rescued by Tommy, who uses his super-speed to infiltrate Virgil's manor house and destroy the device that placed the 'synthezoids' under his control.
Once freed, Jocasta joins their side, but is severely damaged in the ensuing brawl. In a final act, she allows Ultron's code to pair with her swarm of nanobots, giving him a body of his own once more.
Ultron had shown signs of coming around to the human race, but Jocasta's 'death' sends him into a genocidal fury. He sets his lethal bots on a course to London, where they could kill millions in a matter of minutes.
Taking full advantage of their processing power, Vision connects with Ultron and traps them inside an AI-generated sitcom titled UltraVision – taking a leaf out of his late(?) wife's book.
The trite premise even comes with a catchy jingle titled 'Don't Kill the World', penned by WandaVision composers Robert and Kristen Anderson Lopez. Vision hopes that, with enough episodes, Ultron will heed the message.
And yet, after 500 rapidly-generated chapters, Vision appears no closer to his goal. That, he explains, was grimly expected and leads into his contingency plan: mutually assured destruction for himself and Ultron.
The choice is stark: either Ultron reverses his horrific plan, or they both suffer a critical meltdown in a matter of moments.
Having acquired a taste for life, and a form of begrudging respect for Vision, Ultron yields and absconds into the world wide web.
Vision barely survives, but is brought back from (yet another) brush with death through the combined efforts of his sons Tommy and Billy, who made contact on the astral plain at the start of the episode.
Suffice it to say, the brothers and their father have some major catching up to do, but could their mother be joining them any time soon?
In response to Tommy's query, Vision repeats a memorable line from WandaVision: "We have said goodbye before, so I suppose it stands to reason we might say hello again."
(A jaw-dropping post-credits scene suggests it might be sooner than they think.)
What happens to Ultron at the end of VisionQuest?

The main VisionQuest narrative is wound down with an enigmatic phone call from Ultron to Vision.
Disguised by nanobots to take the form of his doppelgänger Virgil Horton, Ultron is cryptic about what his next moves will be.
Vision simply tells him to "be good". In Ultron's hand, we see a hard drive containing Jocasta's code, suggesting that his pursuit of love isn't over just yet.
Of course, whether we'll see a VisionQuest season 2, an associated spin-off, or heck, even an Avengers: Second Age of Ultron, is the stuff of speculation for the time being.
But, given that the MCU has often dispensed of major villains somewhat carelessly, fans will be comforted to see one of them placed firmly back on the board.
VisionQuest is available to stream on Disney+. Sign-up to Disney+ from £5.99 a month.
