The second season of Stranger Things has been a hit – although one episode did prove to be highly divisive.
Episode seven, 'The Lost Sister', wasn't met with a whole lot of enthusiasm by the fans, and although it was nearly cut from the season, creators The Duffer Brothers ruled that Eleven's trip to Chicago was essential for viewers to experience.
It looks as though that episode will have an even greater impact past season two, because one particular character is set to return to the Netflix show for season three.
It turns out you haven't seen the last of Kali, played by Linnea Berthelsen.
The Duffer Brothers stress that although they're still in "very early days" of breaking down the story for next season, they already have a few ideas floating around.
"It feels weird to me that we wouldn't solve [Kali's] storyline," Matt Duffer told The Hollywood Reporter. "I would say chances are very high she comes back."
The Duffer Brothers also revealed that Kali was originally intended to be a man in his 30s. It wasn't until they struggled to find the right person for the role that they considered branching out their search to include women.
As Matt Duffer explained: "Initially, we were actually looking for a guy, that Eleven would have a brother.
"We were looking for 30-year-old men... [Nobody] was that interesting to us and we said, 'Let's open this up, let's open it up to women.'
"And [Millie Bobby Brown and Berthelsen] had, I think, a really powerful connection."
