Stranger Things season 5 finale ending explained: What really happened to Eleven?

Warning: Major spoilers ahead for the Stranger Things season 5 finale.

After nine years, Stranger Things has officially come to an end with the season 5 finale episode The Rightside Up.

The last ever episode saw the Abyss begin to descend on Hawkins, as the gang's theory is proven right, with Eleven (Millie Bobby Brown) and her sister Kali (Linnea Berthelsen) facing up to their brother Henry/Vecna (Jamie Campbell Bower).

Meanwhile, Max (Sadie Sink) and Holly (Nell Fisher) launched another escape, and our heroes' D&D campaign has finally come to an end.

If you're already missing the call of Hawkins, why not check out these other 10 epic series? But, for now, here's everything that went down in the Stranger Things season 5 finale.

Stranger Things season 5 ending explained: What really happened to Eleven and did she die?

Ultimately, what happened to Eleven is left up to the viewer to decide, as we're given two possibilities.

Just as she agreed with Kali at the end of volume 2, as the battle for Hawkins concludes, Eleven seemingly decides to sacrifice herself as the Upside Down is destroyed, in an effort to finally stop Dr Brenner's programme, which has been continued by Dr Kay - however, this might not be the full story.

At the end of the episode, as Mike (Finn Wolfhard), Will (Noah Schnapp), Dustin (Gaten Matarazzo), Lucas (Caleb McLaughlin) and Max finish up their Dungeons & Dragons campaign, Mike uses the game as an analogy to suggest that Eleven might still be alive.

He theorises that, after Kali saw the love from Eleven's friends and family, she changed her mind about the plan. As Kali lay dying, she uses her powers to make Eleven invisible and to cast an illusory version of her into the Upside Down. As the illusion of El appeared to sacrifice herself, the real El sneaks away unnoticed.

As for where she is now? No one knows for sure, but, as Mike suggests she's in a faraway land, we see a shot of Eleven hiking across some beautiful hills, alone but at peace.

But isn't this Mike just theorising and hoping for Eleven's survival? The Duffer Brothers haven't confirmed which version of events is true, leaving it up to viewers to decide which one they believe - almost like our own D&D campaign.

But Ross Duffer did add to Tudum that, for the residents of Hawkins, “she lives on in their hearts, whether that’s real or not".

What happened to Vecna?

After being weakened from attacks by Eleven and Kali, Vecna/Henry (Jamie Campbell Bower) is finally killed. Will manages to face his fears and overpower Vecna, allowing Eleven to drive his body through a spire.

But the final blow comes from Joyce (Winona Ryder), who warns him with some very choice words that he's messed with the wrong family. Taking an axe, she severs Vecna's head from his neck, killing him and ending years worth of nightmares.

Ross Duffer told Tudum of that moment: “At the end of the day, it felt like it had to be Joyce because Joyce was the first one [in Season 1] to really take action, to believe that something strange was going on."

For a moment during the episode, it looks like Henry might be capable of redemption, although ultimately he remains faithful to the Mind Flayer. Speaking to Henry, Will tells him he is also just a vessel and attempts to convince him to fight with them against Mind Flayer.

But Henry won't be reasoned with, and tells Will instead that the Mind Flayer has never controlled him - that he could have resisted - but he chose to join it.

Ross Duffer told Tudum that the truth of that moment is up to viewers, explaining: “We wanted to leave it up to the audience in terms of whether young Henry did choose this or whether it was simply the Mind Flayer controlling him from beginning to end.

“But ultimately, in terms of where Henry goes, it doesn’t matter because he chooses the side of the Mind Flayer at the end of the day.”

What happened to the Upside Down?

As planned, Murray (Brett Gelman) and Hopper (David Harbour) set off a bomb to explode the inter-dimensional bridge once the children have been rescued from Vecna's clutches.

Using Prince's iconic album Purple Rain as a trigger, they set the timer and the wormhole finally collapses, ending years of misery for the residents of Hawkins.

This comes after a final big battle in the Upside Down, in which it's revealed that the Pain Tree (where all the children have been kept prisoner) is actually the Mind Flayer.

With Nancy used as bait, the rest of the gang attack the Mind Flayer from the ground and weaken it while Eleven fights Henry inside the Mind Flayer’s body.

Why was Henry so afraid of the briefcase?

Inside the scientist's briefcase, Henry found a rock containing Mind Flayer particles, which possess him.

For Henry, this moment represents the loss of his happiness, his childhood and life as he knew it - and we finally see the moment Henry became Vecna.

Where did our heroes end up?

Our heroes have gone their separate ways by the end of the episode. Will, Mike, Dustin, Lucas and Max graduate from Hawkins High, with Valedictorian Dustin giving a controversial speech that would have made Eddie Munson (Joseph Quinn) proud, and set off on their separate journeys to college and beyond.

Jonathan (Charlie Heaton) is making a film about anti-capitalism, while Steve (Joe Keery) is coaching little-league baseball and teaching the next generation. Robin (Maya Hawke) is attending Smith College in Massachusetts and Nancy (Natalia Dyer) has dropped out of Emerson College to take a job at the Boston Herald. While the four of them have gone their separate ways, they agree to meet up every month.

Meanwhile, Joyce and Hopper get their happy ending. Hopper reveals he's been offered a job in Montauk (a little nod to the original title of Stranger Things). He then proposes and the pair get engaged, dancing to Etta James's At Last.

With peace finally descending on Hawkins, Mike and the gang end their campaign and head upstairs - only to see Holly and her friends race into the basement to begin an adventure of their own.

Stranger Things seasons 1-5 are available to stream on Netflix. Stranger Things: Tales from ‘85 is coming to Netflix in 2026.
