Why Millie Bobby Brown Apologized to Stranger Things Cast After Finale

Stranger Things' David Harbour Reveals If Eleven Died in Series Finale

Millie Bobby Brown was feeling upside down after Stranger Things ended.

Nearly six months after the Netflix series concluded following five seasons, the actress shared how the finale had taken a toll on her mental health.

"I went into a little bit of a slight, slight depression," Brown told Josh Horowitz at the June 24 live recording of his Happy Sad Confused podcast in New York City, per Variety. "It was very hard for me. I would not have expected that coming off of the show. I'm a very happy-go-lucky person."

The 22-year-old admitted that concluding the show—which ran from 2016 to 2025—left her feeling vulnerable in her relationships with costars like Finn Wolfhard, Sadie Sink, Caleb McLaughlin, Gaten Matarazzo and Joe Keery. So much so, in fact, that she felt like she needed to reach out to "mend" their friendships.

"They probably thought I was crazy," she recalled. "I was like, 'We're still friends, right? Like, you're not gonna stop talking to me anymore?' I was like, 'I'm sorry if I ever upset you,' and was just trying to mend anything. 'It's been 10 years, and I really want to be friends. You're my sibling.'"

"Then I was on the beach, it was beautiful, and I just sat there crying," Brown—who shares a daughter with husband Jake Bongiovi—added. "It was a very hard time for me."

Because not only was Brown saying goodbye to Eleven—whose dramatic fate is still up in the air following the finale—but the end of the series also marked the end of a formative chapter in her adolescence.

"No one will ever understand it," she emphasized. "I started the show when I was 10. This character was me and these people were in my life more than my own family. I saw these people more than going home and eating dinner with my family."

"Saying goodbye to that after 10 years was a very, very emotional thing," she continued. "I'm going to miss Eleven more than anything."

As for the character's ultimate fate, while some of Brown's costars believed that Eleven had actually sacrificed her life at the end of season five, the Enola Holmes actress has faith in a happy ending for the tortured teen.

"All people say now is, 'Do you believe?'" she explained. "Of course, I believe. I have to believe."

As for whether Eleven will eventually reunite with Mike Wheeler (Wolfhard) in a village with three waterfalls? Despite sharing her feelings about the teen, Brown is otherwise keeping her lips sealed—in part because Stranger Things co-creators Matt Duffer and Ross Duffer asked her to.

"They were like, 'Do not tell anyone. Because we made it a secret kind of pledge,'" Brown said. "No one else knows. It's just us three. And what we do with that information, it'll be up to them."
