"Chapter Eight: The Rightside Up" is the series finale of the American science fiction horror drama television series Stranger Things. The eighth episode of the fifth season and the 42nd overall, it was written and directed by series creators The Duffer Brothers. The episode was released on December 31, 2025, on Netflix and in select theatres across the United States and Canada. Its title parallels "Chapter Eight: The Upside Down", the title of the first season's finale.
In the episode, the group enters the Upside Down one last time in a desperate attempt to complete "Operation Beanstalk" by Steve Harrington to save the world. While the others focus on rescuing the kidnapped children, Eleven, Will, Max, and Kali aim to confront and end Henry Creel / Vecna. "The Rightside Up" received positive reviews from critics, who praised the visual effects and the performances of Finn Wolfhard, Millie Bobby Brown and Jamie Campbell Bower, while audience reception was polarized.
Plot In the Upside Down, Mike, Will, Joyce, Lucas, Dustin, Steve, Robin, Nancy, and Jonathan climb the WSQK radio tower in an effort to reach the descending Abyss. At Hawkins Lab, Eleven, Hopper, Murray, and Kali prepare a sensory deprivation tank, allowing Eleven to enter Henry Creel / Vecna's mindscape. Kali and Max are drawn in with her to search Henry's memories.
While climbing the tower, Mike apologizes to Will for ignoring his struggles with his sexuality, reaffirming their friendship. As the group reaches the top, the Abyss begins to descend and collides with the tower, destabilizing it; Steve nearly falls to his death before Jonathan pulls him to safety. In the mindscape, Eleven's group locates Holly and the other abducted children inside the Creel House. Kali hides them while Eleven attacks Henry, buying time for the tower group to reach the Abyss. Henry manipulates Hopper by showing him a vision revealing Eleven plans to die alongside Kali, prompting Hopper to pull Eleven from the tank and beg her to live. Elsewhere, Dr. Kay's forces capture Max and Vickie. Akers' team launches an assault on Hawkins Lab and threatens Kali to force Hopper to reveal Eleven's location. Murray uses a grenade to destroy the military helicopter, which is equipped with a sound emitter suppressing Eleven's powers, enabling Eleven to snap the soldiers' necks and force Akers to shoot himself in the head, though Kali is mortally wounded by a stray bullet and dies. Eleven resolves to confront Henry directly and makes Hopper promise to accept her decision.
In the mindscape, Henry pursues the children into the cave and is forced to relive his past. Holly leads the children into the mine and attacks Henry to buy time. Henry recalls opening a briefcase as a child and becoming corrupted by a fragment of the Mind Flayer. Will pleads with him to destroy it, but Henry refuses, declaring that he and the Mind Flayer are one. In the Abyss, Henry's lair is revealed to be the physical form of the Mind Flayer, which rises as a colossal spider-like creature and attacks the group. Eleven arrives and battles Henry inside the monster, while Nancy draws it into position, allowing the group to use fire and explosives to weaken and kill it. With Will helping by ripping off Henry's arm, Eleven impales him, freeing the children, and Joyce kills him by decapitating him with an axe.
Hopper and Murray arm a time bomb to destroy the Upside Down. When the group returns to Hawkins, Kay and the military—again suppressing Eleven's powers—ambush them. The group quickly realizes Eleven is not with them, only to see her intentionally staying behind. In a final shared moment within her mind, Eleven says goodbye, tells Mike to thank the group for their kindness, and professes her love for him, asking him to understand her choice and to help the others understand as well. The explosives detonate, destroying the Upside Down, closing the gates, and seemingly taking Eleven with it.
By the spring of 1989, Hawkins is rebuilding and the military has withdrawn. Hopper urges a grieving Mike to move forward and attend graduation. Dustin, now valedictorian, honors Eddie Munson in a defiant speech. Steve, Robin, Nancy, and Jonathan reunite at the radio station, having taken odd jobs and pursued their studies individually. Although they fear drifting apart, all four promise to stay in touch. Hopper and Joyce go on a date at Enzo's, where Hopper proposes, and Joyce accepts; he also suggests moving the family to Montauk, where he has been offered a higher-paying job as chief of police.
After a Dungeons & Dragons game at the Wheeler house, now including Max, Mike predicts the futures of the group: Max and Lucas finally go on the movie date they promised to each other, Dustin is a full-time college student but still meets up with his friends whenever he can, Will moves out of Hawkins and feels like he belongs for the first time in his life, while Mike continues to write stories about the group's adventures. He then reasons that Eleven would not have been able to vanish into the Upside Down while her powers were suppressed by the military, and theorizes that Kali, who did not bleed out immediately, used the last of her abilities to project a false Eleven, allowing the real Eleven to escape and go somewhere far away to live in peace. Choosing to believe this, the group tearfully puts away their D&D binders as they head for dinner, while Mike lingers to watch Holly and her friends begin a new D&D campaign before closing the door.
Production The final table read took place on September 8, 2024, and was attended by series creators the Duffer Brothers, executive producer Shawn Levy and the cast. It was the first time the cast had seen the script for the finale, allowing them to experience the last episode together.
Finn Wolfhard said that he was initially concerned the episode could have a negative reception like "The Iron Throne", the series finale of Game of Thrones (2011–2019), but when he read the script, he knew that "it was something special". Despite their love for Game of Thrones, the Duffers felt Stranger Things was a very different type of show to theirs and made sure their own finale avoided excessive character deaths and gave the audience a feeling of satisfaction.
The prequel play Stranger Things: The First Shadow (2023) hinted that the Mind Flayer was what made Henry Creel accept his dark side and connection to the Upside Down, and Matt Duffer hinted that the series finale would finally reveal who "the real evil is". The brothers also stated that the finale would show viewers the second half of the "core memory" from "Chapter Six: Escape from Camazotz", revealing what happened to a young Henry Creel in the mineshaft.
Writing The episode was written and directed by the Duffer Brothers, marking their twentieth writing credits on the show.
The Duffers stated that some unused ideas originally conceived for the second season were implemented throughout the fifth and final season's storylines and that the impact of the COVID-19 pandemic enabled them to completely outline the final season before the fourth season had even been filmed. Following the release of the fourth season, the team were able to rewrite some elements in response to feedback, particularly the finale, but noted that much of their original pitch to Netflix remained unchanged. Levy recounted that the Duffers had pitched the season and its finale to him and others in the production team as early as 2023, showing them a diorama explaining the Upside Down's mythology and their plans to conclude the show "emotionally". Leading up to the finale, the fifth season revealed the truth about the Upside Down and wrapped up a number of major character arcs in preparation for the final battle against Vecna.
The Duffers added that Dustin's valedictorian speech was inspired by the loss of Eddie, adding that Dustin does a lot of the things Eddie told him he wanted to do at his own graduation prior to his death and felt the speech summed up one of the major themes of the show, stating, "this is a story about outsiders and outcasts. It's about banding together and embracing your otherness to defeat the evils of this world". The Duffers discussed featuring the Demogorgons in the final battle with Vecna and the Mind Flayer, with one idea having the group come across a large field of eggs. However, the idea was not pursued as they felt that showing the Demogorgons would have felt repetitive by then, or "Demo fatigue" as they called it; fans perceived this absence as a major plot hole.
Noah Schnapp revealed that he requested that the Duffers write the scene between Will and Mike where the latter reaffirms their friendship, feeling it was important to include following Will's coming out in the previous episode in order to give the relationship closure. He also spoke positively of Will's ending, calling it "perfect" and stating, "it felt really hopeful to see what the future can hold for a character like that, that I also kind of relate to, at least in terms of sexual identity. It was nice to see him get his happy ending and learn that it was never about Mike. It was about finding the person that was right for him, and in the meantime, kind of just loving himself".
Vecna's backstory and fate The episode reveals that Henry Creel was corrupted by the Mind Flayer as a child, as detailed in The First Shadow. The Duffers explained that they did briefly consider having Henry turn on the Mind Flayer but, following discussions with the other writers and with actor Jamie Campbell Bower, concluded that "he's gone so far at this point to get here, he has to justify everything he's done. And the only way to justify that is to go, "I chose this, and I believe in this still. Even though he is shaken by seeing this memory, he's too far gone at this point to turn against the Mind Flayer." They chose to leave it up to the audience whether the Mind Flayer was controlling Henry from the beginning or whether young Henry chose to embrace the evil, noting that "it doesn't matter because he chooses the side of the Mind Flayer at the end of the day". They felt that Joyce had to be the one who delivered the final blow to Vecna, although they considered multiple characters before coming to a decision, explaining, "Joyce was the one in the first season who's the first one to really take action, to believe that something strange was going on. And that fierce love she has for not only Will but her family and the others is a superpower in its own way. And so we thought if anyone is going to defeat this guy, it had to be Joyce."
Fate of Eleven
Regarding the ambiguous ending for Eleven, Matt Duffer stated, "there are two roads that Eleven could take. There's this darker, more pessimistic one or the optimistic, hopeful one. Mike is the optimist of the group and has chosen to believe in that story." Ross Duffer noted "there was never a version of the story where Eleven was hanging out with the gang at the end" and that they felt "Eleven had to go away" in order for the story and the rest of the characters to move on, adding that "we thought it would be beautiful if our characters continued to believe in that happier ending even if we didn't give them a clear answer to whether that's true or not. The fact that they're believing in it, we just thought it was such a better way to end the story and a better way to represent the closure of this journey and their journey from children to adults". They added that Eleven's discussions with Hopper throughout the episode mirror these themes of coming-of-age, noting that "part of coming of age is leaving your parents and making your own decisions", and that Hopper has to finally accept that Eleven is her own person and move on from his guilt over the death of his daughter.
