Stranger Things has exploded into a pop cultural phenomenon since debuting in 2016, which is due in a large part to the incredible performances from its core cast of young actors like Millie Bobby Brown. But can you imagine the show without Brown's Eleven? That plot twist almost came to be in season one, as well as the death of Joe Keery's beloved Steve Harrington (though, to be fair, he wasn't nearly as well-liked in the first season).
"Eleven was going to sacrifice herself to save the day," Ross says in the book, Stranger Things: Worlds Turned Upside Down. "That was always the end game." But when the Duffers discovered that the sci-fi series would return for a second season, they "needed to leave it more up in the air, because deep down we knew the show just wouldn't really work without Eleven. And at that point, we knew how special Millie [Bobby Brown] was. If there was going to be more Stranger Things, Eleven had to come back."
As we all know now, Eleven escapes from the Upside Down and is kept hidden by Chief Hopper until he deems it safe for her to rejoin her group of friends, which now includes a devoted babysitter in the form of one Steve Harrington. It's hard to imagine it now, but the Duffers also planned to kill Steve by the end of the first season. "This Steve character, he was just supposed to be this giant douchebag," Ross said, before noting that it was Keery's performance that changed their minds.
So, what's next for the characters? In July, Netflix gave us a brief glimpse at the third season. While it was great to plop into Hawkins for 90 seconds and to hear about the brand-spanking-new mall that's coming to town, the teaser also revealed that we'll be waiting until Summer 2019 for the show to return.
