Stephen Strange has saved the world and the universe, he's master of the mystics arts, and runner-up Sorcerer Supreme, he's got this. But when a multiversal traveler tumbles out of a star-shaped hole in reality, Doctor Strange comes face-to-face with the Scarlet Witch, who can rewrite reality as she sees fit. Can Doctor Strange uncover the multiverse-spanning plot while gaining the trust of a girl his variant tried to kill in time for both of them to save all realities?

This is a fan-rewrite of the script. I really wanted to see Wanda’s character more fleshed out, and utilize the variant Wanda to her full potential. Additionally, I wanted to see more of the America Chavez we see in Young Avengers.

The movie opens not in the aether of the Gap Junction, but in a dark slimy tunnel where the impressive Cyttorak chases America and a nearly dead Defender Strange, trying to heave its fiery mass through the small tunnels. I love the classic horror feeling of it.

A variant Scarlet Witch claws her way into reality in the wake of Defender Strange trying to take America’s magic by force. She toys with him, she wants the Illuminati. when he can’t help, she burns him alive and continues her quest.

Stephen gets a message from his fallen variant but ignores it, even though Wong seems troubled by it.

America falls into his life, doesn’t trust him and the two have to fight Shumma-Gorath. America just wants to run, but Stephen wants to know what’s happening.

Visiting his Wanda, he discovers she too is using the Darkhold and mistakenly blames her for chasing America. Our Wanda is living in a new Hex with her boys, unable to see that their really two demons she’s summoned, and her hex is actually a reality destroying incursion in progress.

Stephen pushes her, sending sorcerers after her, and leading to the death of Wong and so many of his fellows, and forcing America to save his life by pulling him into the multiverse.

The Illuminati give chase, as does the variant Scarlet Witch, all leading to a show down between variant Scarlett Witch and the Illuminati after she discovers Wanda alone in her orchard, revealing that the boys in her original hex, were stolen infants from another reality.

Scarlet Witch easily defeats all the Illuminati but Professor X, and unwittingly lets the demon Cthon fully into her mind to help battle the powerful mental mutant.

With Cthon’s grip now firmly on Scarlet Witch, he leads her to the extra-dimensional Wundagore where he promises her she can keep her children safe forever, by performing a spell on the missing last page of the Darkhold. (Actually intended to release him and allow him to possess young Billy.)

Stephen and Wanda have to come to terms with both their blame in this mess, and work together. Our Wanda is not a Scarlet Witch, she is The Scarlet Witch. The mind stone means she can find the hidden temple, and her new powers allow her to temporarily resurrect Wong.

The team faces an almost un-winnable face-off, until America realizes that Billy and Tommy can help. Tommy and America recruit five more Charles Xaviers to help. Billy teams up with Wanda to try and get through to his other mom. And Stephen and Wong work together to push Cthon out of Professor X’s mind.

But Cthon isn’t done, he seizes Billy and casts a new hex where only Billy has power. He doesn’t know what Wanda will do to keep her children safe though. Even facing pain and suffering at the unwilling hands of Billy, Wanda still wrenches Cthon’s control away.

Wanda sends the boys back to their birth mother, and takes that Scarlet Witch’s power, power connected to the temple itself.

America, Stephen and Wong cast a new spell to seal the rifts, and Wong stays behind with Wanda to make sure that the power she draws from Cthon goes into the spell correctly.

As Wanda explodes with her chaos energy, shooting the healing spell out of Wong’s hands and into the multiverse, she whispers, “Let them live.”

Palmer returns to clean up the Illuminati’s mess, and America joins her. Variant Wanda and the kids welcome home a different Vision. And Stephen goes to see Christine, finally understanding her lesson, and she hugs him while he cries for Wong’s loss.

Strange is now Sorcerer Supreme, and he’s got a lot of work to do.

And stay tuned for some mind-blowing post credit scenes. :)

America Chavez is injured and great in danger, being chased by the fiery demon Cyttorak hellbent on getting its mummy-like wrappings on her. Another Doctor Strange from a different universe tries to protect her, but the demon has them trapped in tunnels deep beneath Manhattan and time is running out. The demon is a minion for a dangerous witch, and she wants America's powers. Broken and bloody, the demon about to snatch the witch's prize, Defender Strange makes the wrong call, and tries to take America's magic before the witch can get it.

Terrified, filled with horrible agony, America Chavez uses some of her innate magic and breaks free of the alternate Doctor Strange's grasp, finally gathering enough strength to kick a star-shaped hole in reality and escape the demon and the sorcerer who just tried to kill her.

Before the demon can kill the wayward doctor, the Scarlet Witch uses it to claw her way into yet another reality. All she wants is the Illuminati, and to punish the thief who set her on this path. She burns Strange and the Demon into ash for their failure to help her with her mission. But before she can settle down to continue her search for the elusive, America Chavez, the dying doctor sends an SOS into the multiverse, warning everyone that "She's coming."

A call that wakes our Doctor Strange from a nightmare and summons Wong, Sorcerer Supreme of Earth 199999 to Stephen's bedside. Doctor Strange dismisses his dream and the echoing terror of his voice in the cosmos, paying lip service to Wong that he won't go galavanting off on his own again. Mostly because Stephen has an appointment to see Doctor Christine Palmer for his check-up.

No one except for a young boy recognizes Stephen on the subway, so when he steps off the train and into a macabre vision of his variant's zombie body puppeteered by the equally dead demon that chased him, Stephen stumbles out of the vision into the ire of his fellow passengers. Shaken, Stephen considers contacting Wong, but he decides he's master of the mystic arts, and he can handle a bad dream.

Christine, now head of ER, is happy to tell him that he's in great health for an aging sorcerer, though his hands are unlikely to ever be remade, short of a Stark-level miracle, something that isn't possible since Thanos. But she does tell him his ego needs a check, he nearly ruptured reality for Spider-Man and he still acts like he can save everyone, every time. She reminds him he is a doctor, and you can't save them all. And even doctors have to answer to someone.

Before he can respond, America Chavez tumbles out of her portal into Christine's office, bloody, banged up and scared out of her mind when she sees Stephen standing over her. After a chase through the hospital, Stephen leads the super-powered teenager out onto the street and away from any patients that might get hurt.

Only there's another inter-dimensional demon, Shame-Gorath, who makes Cyttorak look like child's play. Christine had the good sense to call Wong, so that when Stephen makes the invisible kaiju visible, he has some help in tackling the monstrous tentacles behemoth. Stephen notices the glowing runes all over the beast, the same runes America say on Cyttorak. Figuring out the beast is only partially in this reality, he attacks the source of the problem directly, only to release the monster from the Scarlet Witch's control. Quick thinking on America's part helps the surviving sorcerers, Wong, Sara and Stephen, drag this avatar of the demon into a portal and out of NYC.

America collapses in Wong's arms and Christine decides its best Stephen was elsewhere when the magical girl wakes up, her wounds already starting to heal. Stephen accepts her decision, taking Wong aside to discuss the monster mayhem. Wong reveals that he recognizes the runes from a description in the Ancient One's private library, they are from the Darkhold, a forbidden spell book laden with the demonic power of Cthon, an entity of profound evil and thankfully locked outside our reality. Wong suggests that its time to pay a visit to Wanda Maximoff, the only witch they know.

Wanda is awaken by Billy, her magical son, who heard the multiversal warning as well. Tommy, his twin brother, teases him for running to mommy. They fight with their powers and Wanda tells them for the thousandth time, "No powers in the house." Which leads to a giant cuddle puddle with everyone still in their pajamas.

Later, the boys have breakfast and Wanda tries to explain to Billy that the two of them have powers that can extend beyond what's around them, even into other realities. Tommy hates that his brother gets a cool power, while all he can do is zoom around Wanda's new mini-hex, the dome of power that lets the boys exist at all. Wanda hates it too, but promises them she's trying to find a way to fix it all.

School time is interrupted as Stephen approaches the house. Fearful, Wanda tells the boys to stay in the house while she goes out to meet the sorcerer. Over coffee, Stephen tries to get information about witches and runes, only to discover that he's walked into another of Wanda's hexes, and what's more, it's powered by the Darkhold, Cthon's reality ripping magic already causing an incursion there in Wanda's orchard, filled with desiccated trees and a broken down house, her boys actually two demons. But she can't, won't see anything except her fantasy, and warns Stephen that if he ever comes back, it will be the Scarlet Witch who greets him.

Stephen is on a mission now, though Wong isn't convinced that our Wanda is the same one that is hunting America, noting that the Darkholds are all just copies of Cthon's temple, safely outside of reality. Stephen wants to fix the breaks that Wanda is causing and the only way to do that is to take the Darkhold away from her. They make a plan, using the full might of Kamar-Taj and Earth's strongest sorcerers, along with their ace-in-the-hole, portal kicking America Chavez.

But no plan survives contact with the enemy. The advance force, intent on drawing Wanda away from he Darkhold, manages to walk into reality warping magic that defeats all but three of them, Sara and Rintrah among them. What's more, Wanda is still tucking her boys into bed while simultaneously fighting off twenty sorcerers in her astral form.

When that same astral form begins to reign down hell on Kamar-Taj itself, melting sorcerers and stone in retribution for their attack, Stephen convinces Wong that they still have to go through with their plan, assuming Wanda must be unconscious back at home. Wong relents and America takes them to the orchard, able to get inside the hex with her special portal magic.

Except Wanda isn't unconscious, and Stephen comes face-to-face with the Scarlet Witch, who defeats Stephen with a gesture. Furious, holding Kamar-Taj under her unceasing assault, she wants to know why Stephen breaks the rules and becomes a hero, but she's a villain. Noting the unfairness, Wanda disintegrates Wong with a flick of her fingers, and nearly incinerates Stephen if not for America saving his life, kicking them into the Gap Junction, a space between all realities, littered with the remnants of buildings and odd statues.

They may have escaped Wanda, but when Stephen opens the Darkhold to find answers for stopping her, he instead draws the attention of the Illuminati, their Ultron sentries emerging from windows in space. Again America is forced to kick them to safety, and since this isn't her first run-in with the Illuminati, she has a plan.

Stop number one: an animated reality from X-men 97, with huge purple sentinels to distract the now dumb Ultron sentries, so she can kick them out of that broken NYC to another broken city, this one in a reality where Ultron won. She's done this several times, and it always works, as long as they hunker down for a minute in a safe house under Central Park, now long abandoned by this Earth's one-time heroes.

America watches Stephen try to understand the Darkhold while the pair start to get acquainted, even though America still doesn't trust the man who shares a face with her attempted murderer, and just got a lot of his 'family' killed by a crazed Wanda. Their potential bonding is interrupted by another avatar of Shuma-Gorath, the witch has found America again.

This time they run for their lives through portals as the tentacles of the intra-dimensional demon chase after them. From live action to animated to comic book panels, they run, until America takes them to a surreal universe where they are just columns of paint, where finally the tentacles lose them. Before their paint can get splattered, America 'head-buts' her way into Earth 838.

It's a utopian place, with clean energy, flying cars, everyone wearing monotone clothes, which makes the colorful duo stand out quite a lot. Even trying to escape notice down an alley doesn't help because, another Christine Palmer recognizes that cloak all too well. Palmer is confused at first, thinking another Strange just wandered into her universe, but when she sees America, she sounds the alarm. America thinks she's safe, having distracted the sentries, but is disabused of that notion when the Illuminati themselves emerge from space-windows to ensnare them, America literally as Reed Richards wraps her up to stop her from escaping.

Stephen is confronted by a variant Mordo, this one a Baron, as well as the ever-ready Captain Carter. Stephen tries to defend himself, but his normally yellow eldritch magic, has turned purple, the color of dark magic. Mordo threatens America and Stephen gives himself up. The two are escorted through space-windows into the Atrium of the Illuminati Fortress as it floats through the slightly luminescent Gap Junction.

Richards and Palmer are thick in conversation about how America has escaped them for so long, while Mordo gloats over finding Stephen with a copy of the Darkhold. The captives are escorted off to Palmers lab. There Palmer shows Stephen how variants of his always have slightly unique breakages in their hands. She and the other also tell him he's from Earth 616, though she's confused when she discovers his Earth has no mutants, no Fantastic Four, and even her computer seem confused, switching between 616 and 199999 on her display. What they aren't confused about is that America Chavez is a wanted fugitive with a rap sheet longer than Stephen's precious cloak.

Mordo takes Stephen on a tour of the Atrium, a monument to the glory of the Illuminati, complete with towering statue of "Strange Supreme" the founder of the Illuminati and the reason why they have so many plaques celebrating their victories over Stranges who thought they could tamper with the multiverse. Mordo allows that its not always a Doctor Strange to blame, they've had their share of Starks and Pyms, but Mordo seems to relish in the Strange incursions.

Stephen tries to bring the discussion back to the Scarlet Witch who is the real culprit, and finds Mordo certain that the Illuminati have the key to that dilemma as well. Mordo takes Stephen deep into the fortress, into the bowels atop which the Atrium and labs are built. It reeks with dark magic, and at the base of that spiral staircase, is a magical undercroft, where four copies of the Darkhold sit on plinths in a never-ending cathedral like space. The vaunted Illuminati are based on the same dark magic they purport to keep everyone safe from.

In the undercroft, Stephen meets the spandex splendor of Blackbolt, leader of the inhumans, and the unassuming Professor X, who decides that if he is to help them, Stephen should know the truth of the Illuminati. Their founder was deeply corrupted by the Darkhold, but found a way to use that dark magic to help prevent other cataclysms. Brining in Mordo and Richards, "Strange Supreme" really Sinister Strange, was able to find ways to blend technology and magic and the shiny Illuminati was born, Ultron sentries and all. But Sinister Strange had a secret, Cthon's power over him was growing, and it was causing multiple universe incursions. In the remnants of one such place, Sinister Strange kneels before his assembled Illuminati and tells them he must be stopped before Cthon can have his way into this world. Blackbolt steps up and disintegrates him with a word.

Before Sinister Strange died, he left the Illuminati a path to destroy all the Darkhold copies, everywhere. But they needed a fifth copy, one which Stephen just walked through their front door. And they need a Doctor Strange to carry the plan out, specifically one who has touched the dreaded book of the damned. Stephen isn't the least surprised by any of this, and he uses his little leverage to bargain for America's release. Mordo assures him she will be free.

Professor X shows Stephen the spell Sinister Strange left behind in his mind, and Stephen steps into the vaulted undercroft and prepares the spell. The runes he draws with purple magic grow brighter with each worm-spell he conjures, needing five to infect the five copies before him all at the same time in order to accomplish this feat of multiverses magic. Stephen strains to complete the spell, and in a blinding flash of light, it is done. The Darkholds begin to crumble, victims of their own magic.

At the same moment that Stephen is preparing to destroy all Darkholds, everywhere, Wanda is curled up on the couch, safe inside her hex, with her two demons that she sees as her boys. They watch the Black Cauldron and Billy decides he wants the prince, but Tommy can't decide between the prince and the princess, admitting he'd rescue both. As Wanda goes to get more snacks for them, she feels the spell Stephen has cast, working its way through the multiverse. When it reaches her hex, it turns her fantasy world back to red, and she sees the demons she was pretending were her boys. They are sucked through a crack in reality that she had opened, and Wanda blasts at that crack trying to get them back, pouring all her fear and rage into it.

Fear and rage that the Scarlet Witch, still floating above the ashes of Defender Strange and Cyttorak hears like a clarion bell. Using her own reality twisting Darkhold magic, she slithers her way through the echo of America's portal on a mission to find her thief.

Professor X takes control of Stephen's body and marches him back into captivity. Mordo lied, and Richards is all too excited to get America under a microscope to see how her multiverse stomping powers work. He thinks one day, his technology might even be able to move through time as well as space. The Illuminati could just prune those nasty branches before anyone even thinks of an incursion. Being led back through Richard's horror lab, Stephen sees Billy and Tommy, the boys from Wanda's Hex, being held captive under sedation. He finally sees, the Darkhold corrupted all of them, not just Sinister Strange.

Back in Palmer's lab, Stephen fumes over the captivity of children. America tells him she was twelve when they first tried to capture her. Perhaps because of their dire circumstance, America tells Stephen about her home dimension, some called it the Utopian Parallel, breathed into existence by the Demiurge. She was small and she didn't know about her powers when she accidentally opened a portal into the gap between realities. Her mothers tried to stop it, to close it, but in her fear, America opened another portal, falling backward to the sight of her mothers trying to stop what she caused. She was adopted and raised well, but she points to the gap junction above them, the remnants of her world, and tells Stephen she knows what the Scarlet Witch is feeling.

Palmer overhears, knowing about America's past, but she didn't realize that America was so young when it happened. Stephen sees her humanity is still there and he pleads with her to let America free. She can save the boys and take them far away from here. Before Palmer can give an answer, Mordo arrives to bring Stephen to his trial. High an Dias in a white throne room built to exhault the seven seats of the Illuminati, Professor X calls Stephen to account for his crimes.

Back in her ruined orchard, Wanda sits in the broken pieces of her once fantasy home, and feels the weight of the reality she has broken. When the Scarlet Witch begins to slither and pool out of the crack she opened, she is at first hopeful that it's her boys somehow returning to her, only to find the Scarlet Witch trapping her just like Agatha had.

The Scarlet Witch tells her of her true crime, ripping away infant sons from their rightful mother and dragging them into her hex. Wanda didn't know, but the Scarlet Witch doesn't care, because Wanda's hex has preserved America's portal long enough for her to finally reach the Gap Junction, the place where the Illuminati hold her sons. The Scarlet Witch turns Wanda's hex into a glass prison, one Wanda is powerless to escape. One where she will live, always knowing that she can never have her boys again. And with that curse, the Scarlet Witch crumples her way into the Gap Junction. And lets out a roar of rage and triumph that echoes through the Gap Junction.

Meanwhile, Stephen calls the Illuminati to account for their actions, but finds tired faces who have heard countless Doctors Strange plead for their lives. But Stephen is able to admit his mistakes, admit that he went too far in his zeal to fix everything and everyone. He willingly summits to judgment as soon as the Illuminati submit to their own. Richards and Blackbolt try to speed up the process while Professor X delves deep into Stephen's mind.

That's when the Scarlet Witch's wave of rage and triumph hits the Illuminati compound, just as Blackbolt is drawing breath to wipe Stephen from existence. Professor X, mind waves rolling off of him, seizes with the shear weight of the Scarlet Witch's energy, and causes everyone in the Throne room, including Blackbolt to cringe and cry out, Blackbolt's cry of anguish blasting upward, breaking through the throne room and the dome above, giving the Scarlet Witch a beacon to follow. A desperate mom's echo-location.

Stephen knows she's finally found them, but the Illuminati believe themselves prepared. Richards, Carter, Marvel and Blackbolt go to confront the witch, while Mordo is left to guard Stephen, Professor X telling him not to kill this Strange out of "petty jealousies," before retreating to guard Billy and Tommy, a dark hint that their reunion with their mother could spell the end of all realities.

The Scarlet Witch gives the Illuminati an option, take her to her children and she will leave them be. Richards tries to reason with her, pressing forward, trying to connect over having children himself. Scarlet Witch asks if his wife is alive, so "there will be someone to raise your children after you're dead."

Richards springs into action, catching the Scarlet Witch up as he did America Chavez, and warns her that Blackbolt can destroy her with a word. She is done being man-splained and warns Richards if he speaks again, she will unravel him. In fact she's tired of men in general telling her things, so she takes away Blackbolt's mouth.

The inhuman had already drawn breath to blast the Scarlet Witch and as the fear of his mouth dripping and sealing overwhelms him, he lets out the tiniest of grunts and blows his own brain out, brain matter dripping from his spandex headpiece, as well as out of his nose.

Richards was already warned, he is unravelled and Scarlet Witch leaves his head for her to smash under her boot, red energy splattering his big brain all over the floor.

Now it's just Carter, Marvel and Wanda. Marvel takes the lead, infinity stone power vs. infinity stone power, and its a spectacular fight of cosmic vs. chaos, one which is even handed. Carter eagerly joins the fight to tip the scales, the pair of Carter and Marvel pushing the Scarlet Witch back, burning the ground beneath her and threatening to take her down completely. But when Carter rushes in for a killing stroke, Scarlet Witch just smiles, "I thought you'd stand there all day watching."

Scarlet Witch strips Carter of her Union Jack shield and uses it to deflect Marvel's cosmic blasts, sending the space warrior out into the Gap Junction, a wave of devastating cosmic power rushing over the Illuminati compound, cracking walls and disintegrating objects. Carter rushes Scarlet Witch and gets knocked down with a broken nose. Scarlet Witch tells her "You can give up now." To which Carter retorts, "I could do this all day." Carter gets the jump on the over-confident Scarlet Witch and cracks her head down on the Atrium floor. Scarlet Witch sees red.

Palmer is trying to get her fellow lab workers into portals and off to safety just as the blasts of cosmic energy rolls through her lab, leaving devastation in its wake. America quips that she's a lot safer in her cell then Palmer is outside.

In the Throne room, Mordo and Stephen banter, Stephen wants to know what the Professor meant by "petty jealousies," just before the wave of cosmic energy rolls through the room. Mordo protects Strange with his green magic, sword out as a kind of shield against it. Stephen tells Mordo "Doesn't sound like your buddies are doing to well out there," to which Mordo holds, "The Illuminati will prevail. We always do. No threat to great."

But Stephen sees through his bluster and begins to push him. "I see it now," Stephen tells him, "The arrogance." Stephen tells Mordo he understands why every Mordo tries so hard to kill him, they don't like seeing their own flaws in Doctor Strange. Our Stephen is finally understanding what he looks like to the rest of the world, and he understands the flaw.

Stephen pushes him, "Why would you be jealous then?" Mordo claims that now, Stephen has nothing that he could want. But before, his Doctor Strange, the Ancient One on his Earth, stripped him of nearly all his magic and almost killed him for calling out the hypocrisy which kept this Ancient Strange alive so long. So Mordo clawed his way back to power, something Stephen could never understand. Mordo was denied the pleasure of killing his Strange by Dormammu, Ancient Strange sacrificing his life to seal Dormammu away.

Stephen sees it now, the jealousy. He asks "You wanna know why I'm so good, why I could work that spell but you couldn't?" Referring to the one that destroyed the Darkhold. It's because our Stephen died countless deaths wearing Dormammu down, and each death taught him something new, and made him better. He did work for his power, and he died to earn that knowledge, again and again and again. Stephen has Mordo on the ropes, pressing him harder and harder, wondering how the great Baron Mordo is taking orders from a wizened professor in a floating hover chair.

Marvel is back and she and Carter are pouring their might down on Scarlet Witch. Marvel and Scarlet Witch lock each other, inches apart, energy blasting from both their hands, each at the other. Carter sees her opportunity, and throws her shield, right at Scarlet Witch...

Only Scarlet Witch reverses her fate, in slow motion, Scarlet Witch defeats the cosmic blasts and grabs Marvel's wrists, drawing all her cosmic energy, all that infinity stone power in her, out and into Scarlet Witch. Pivoting them in a snap, Carter's shield slices straight through Marvel, cutting her in half. Carter watches as Marvel's guts fall to the floor.

Scarlet Witch confronts a broken Carter, a woman who killed the only person that mattered to her. For her sins, for letting monsters take Scarlet Witch's children, Carter is cursed to walk the multiverse, watching all those other people find love and happiness, never allowed to find it herself. Tears in her eyes, Carter opens a space-window and leaves the atrium behind, commanded to live, "and when you dream, dream only of her."

Free of impediments, Scarlet Witch joins Stephen and Mordo in the broken throne room. Mordo is as easily overcome as Wong was, bound and held for judgement. She thanks Stephen for destroying the Darkholds, without him she would never have found the Illuminati and her children. She asks if Stephen can take her to her children, and he agrees. For that she offers a favor, he can decide Mordo's fate. "I'm not an executioner," replies Stephen. Scarlet Witch abides by the decision, but strips Mordo of all his magic, telling Stephen, "Sometimes death is a mercy."

Stephen keeps his word, and takes Scarlet Witch to Richard's lab, but Professor X is ready. Even as Scarlet Witch picks up an unconscious Tommy in her arms, the Professor attacks her mind. He dismisses Stephen, sending him off to Palmer, instructing him to free America and go. Stephen tries to resist, but he cannot fight the mutants compulsion, finding himself in the lab not of his own will. Palmer frees America on Professor X's orders, and the trio head off to collect their belongings.

Meanwhile, in Scarlet Witch's head, Professor X tries to put the naughty witch in a mental time out, trapping her in a windowless box in her own mind. Only Cthon is there, speaking to her, soothing her, asking her to let him in. Together they can escape. Together they can protect her children. Wanda relents, and the demon enters her mind, pushing back the seemingly omnipotent professor and seizing control of the mutants mind.

Before he is consumed entirely, Professor X tries to tell Stephen that he must trust Wanda, our Wanda, that "only your Wanda, both of them together..." His last warning is cut off as Cthon takes full control of his mind. Palmer tries to open a space-window to Earth 616 but her device won't let her, its not responding. America kicks open a portal and they flee the fortress, back into Wanda's rotting orchard.

Back in Richard's lab, Scarlet Witch wakes her children. They don't know her, but Billy senses their connection. They remember being pulled out of the hex, literally de-ressing. Wanda left them alone in the dark, and they woke up here, in the den of monsters. Scarlet Witch holds them and asks the professor, now controlled by Cthon, if Charles is dead. Cthon assures her he is too valuable to kill, and asks that she open the portal to Wundagore, where they can finish this.

In the demonic temple, Scarlet Witch tries to explain what's happening to her boys, but she isn't quite sure of it herself. Only that it's what she needs to do to protect them. Cthon tells her that the hexagonal dais in the middle of the temple is the last page of the Darkhold, never copied, left only for her. With it she begins to cast the unknown spell, hovering in the shadow of her prophecy, huge and carved in stone on the back wall.

Billy pulls Tommy aside, "something's wrong." Tommy sees Billy in his Wiccan outfit carved into the missing part of the Scarlet Witch prophecy that Stephen pointed out earlier. The pair of them realize they remember being in Wanda's new hex, like a dream, but it was still real to them. They both look at their real mom, maybe wishing they had Wanda instead, and hope that Scarlet Witch knows what she's doing.

Back in the orchard, Palmer sees the evidence of the incursion, and its progressed very far, time is critical. Also she can't understand why her device is telling her they're on Earth 199999, wondering if America took them to the right universe. She points at Wanda and Stephen tells the pair of them to stay there, he needs to speak with Wanda alone.

Face-to-face once more, Stephen and Wanda. Stephen tries to blame Cthon for what Wanda did, but she won't let him take her power or her blame away. She did what she did, however misguided, and she would own that, even owning the destruction of the multiverse. But Stephen stops here there, he's just as much to blame, it was his attempt to fix everything, to save everyone that pushed Wanda in the first place. They both have something to answer for.

Stephen shares that Professor X's last message was to trust Wanda, but he knows how hard trust can be after working with America. Wanda assures him that together, they can find a way to fix this. America interrupts their little therapy session and shatters Wanda's cage. Wanda finally dons her Scarlet Witch regalia and they are ready for action, but they don't know exactly what to do.

Stephen destroyed all the Darkholds, but Scarlet Witch is still using that power. They need Wong, but Wanda killed him. She tells Stephen that she has the ability to temporarily bring him back, and Stephen allows it, knowing he's gonna be pissed. Which he is, especially at the incursions, but not any less at Wanda. He agrees to help them, but only if Wanda summits to judgment for her actions. That settled, Wong tells them exactly how Scarlet Witch is still using the Darkhold's power, Wundagore. But no Sorcerer can travel there.

Stephen puts it together, he Wanda is the only Wanda who isn't a mutant. When she brought Billy and Tommy over, Richards told him that Wanda erased their X gene. Wanda remembers Agatha's words, "The Scarlet Witch is born, she is forged." Wanda isn't a Scarlet Witch, she is The Scarlet witch. And Stephen reminds her she has a part of the mind stone within her, one that she managed to recreate into her Vision. With it Wanda can reach her children again, find where they are.

But America can't take them there if Wanda's the one doing the finding. Last time she kicked a hole to nowhere, her universe was destroyed. America thinks she knows what has to be done, what Scarlet Witch was trying to do all along. Wanda needs to take her power. She submits herself to death, thinking that it will make up for all the horrors she caused as a child. Wanda accepts the offer, but they both are in pain as Wanda starts to take her magic like Agatha did to her.

Stephen can't stand it, and he stops them. He knows there's a better way. The mind stone, Wanda, can link with America. It isn't about power, it's about surrender. Joining together, Wanda and America journey through America's memory of her moms, and use that thread of love to follow Wanda's boys through realities and dimensions, until they find Wundagore. Only Cthon, in Professor X's powerful mind, sees them and tries to push them away.

Stephen defers to Wong to make the plan. Which is simple, and of course doesn't go as intended. Wanda tries to face Scarlet Witch head on, but she's too powerful being bolstered by the temple. Stephen tries to get to Professor X to remove Cthon's influence on Scarlet Witch, but the mutant's mind is too powerful, Stephen can barely move. And America and Wong try to get the boys to safety, back with Palmer, only to find them ready and willing to fight back.

America sees the problem the same time Wong does. They need a way to stop Professor X, they need more of them to overcome Cthon. America takes the boys aside and asks them for their help, sharing her own experience with having two moms who fought sometimes. Billy transforms himself into Wiccan, and Tommy into Speed, who helps zoom America through the multiverse, while Billy goes to help Wanda try to break through Scarlet Witch's shield and stop the spell. But the portal to Cthon is almost open.

Wong goes to help Stephen, and as America and Tommy recruit a new Charles Xavier, Cthon's mental attacks lessen and the sorcerers are able to get close enough to try and imprison him. First they get Charles from the Fox movies. Then they get young Charles from First Class. Then it's two animated Charles and finally the Comic Book Charles from House of X. Together, the five variants are able to contain Cthon's influence on Professor X, Stephen and Wong are able to entrap him.

Scarlet Witch isn't free yet though, Cthon calls her to attack Wanda and Billy, blinding her to the truth. She does and Billy must protect Wanda, America and Tommy. Stephen asks the now free Professor X if he can pull Scarlet Witch into Wanda's mind. He does, and Scarlet Witch finally is able to see what she's doing, the fear and pain in her boy's eyes. Wanda tells their boys to go to the their mother. Scarlet Witch embraces them and Wanda apologizes for being the thief.

Back in the temple, America knows what has to be done, the temple itself is the Darkhold and it needs to be destroyed. Working together, Scarlet Witch and Wanda start to seal the portal that was opened, but Cthon isn't done yet. When Billy joins to help, Cthon spears him with a harpoon of magic, seals the temple in a hex where only his magic will work, and incinerates Professor X. His two mom's have to decide between destroying the temple or saving their son.

But Wanda already knows what her choice is. She calmly walks forward as Billy unwillingingly tries to stop her. He can't fight Cthon, but Wanda assures him, all he needs to do is give her a hug. Billy burns through her suit and even wounds her stomach, but through suffering and persistence, Wanda hugs her son...and seizes Cthon's harpoon, freeing Billy to remove his hex.

Her powers back, Scarlet Witch tells her together they may be able to destroy the temple, but Wanda knows the boys need a mom. Scarlet Witch gives Wanda her power, and takes the boys to safety back in the orchard. Wanda tells Stephen and Wong to work with America, use her power to find every crack, every broken piece of the multiverse touched by the Darkhold. Wong and Stephen use a modified Runes of Kaf Kaul to accomplish this, America's own blue magic providing the inter-dimensional boost the spell needs.

The spell ready, Stephen tries to be the one to hold it until Wanda destroys the temple, but Wong stops him, reminds him to save his patient, that the world will need a Sorcerer Supreme. Stephen understands, he isn't the one to save everyone, every time. He has to see to the rest. Withdrawing, Wong and Wanda are left alone. Cthon threatens to possess Wanda instead of Billy, but she's not having any of it. Gathering the power of both Witches into a nova of chaos magic, she explodes, her last words are "Let them live."

As the temple is destroyed, that energy races into Wong's spell. He and Wanda are gone, but their work races through the multiverse, fixing the holes, patching the cracks and stopping all the incursions everywhere.

Stephen, America and Palmer watch as Scarlet Witch and her boys fade away into light, returning to their rightful universe. Palmer retreats back to her lab, there's a lot of work to do, especially with the Illuminati gone. But she's happy to find our her device, which we get to see is an early kind of Temp-Pad seen in Loki, finally registers Stephen as being on Earth 616.

Stephen goes to his Christine and with tears tells her what happened to Wong, he finally knows he can't save everyone, but Christine reminds him, "You can save some." On the TV, the recent exploits of the X-men are recounted, as well as continuing tensions with Genosha and their self-proclaimed leader Magneto.

Scarlet Witch finally gets to be mom, as she, Billy and Tommy greet a new Vision than the one we know at the door. They are happy. They are a family.

Stephen tries to convince America to stay, now that he's Sorcerer Supreme, and maybe she can learn some more about her magic. But she tells him its better if she keeps moving, and kicks a portal open to Palmer's lab. The doctor is unsurprised to see America return. America gone, Stephen has to oversee the reconstruction of Kamar Taj. Just like his Christine, it looks like a lot of desk work is in his future.

Mid-Credits Scene:

Stephen leaves the Sanctum, normal day just like the beginning of the movie, only this time he's grabbed on the street by Clea, who cuts a portal into Agatha's kitchen where she's still somewhat stuck in Wanda's curse. Oh and Magic and Sister Grim are patiently awaiting her cookies. Clean smiles at Stephen as Agatha tells him it's about time they "got her girl back." Cut to black, Agatha cackles.

End-Credits Scene:

An empty room begins to magically transform into a modern gay-boy's bedroom. There's a hot shirtless poster of Ice-Man, and a Pop Princess in all her glory. There's multi-colored lip gloss and deodorant mixed with metro pass and loose coins. A bed of red blankets and pillows, a pride flag on the wall. And finally the red magic resolves into an Older Billy, teenage-ness in full swing, and he's amazed to see his face in the mirror, poking and prodding at it. At least until his mom storms in, "Billy Kaplan, you get dressed for school this instant." Billy rolls his eyes, reality settling into place as he tries to decide what to change his short shorts and mutant-band t-shirt in for, using magic to spirit his choice out of the closet.
