Season 2 of Stranger Things brought all kinds of changes to the show, but perhaps none has been as divisive as the introduction of new character Kali, played by Linnea Berthelsen. In 'Chapter Seven: The Lost Sister,' while the rest of the denizens of the town of Hawkins were off figuring out how to defeat the Demogorgons, Eleven took a side trip to locate the girl from her mother Terry's memories.
The result was a bottle episode that deviated from the main storyline but allowed the series to experiment a little bit. Kali, AKA Eight, was once imprisoned at Hawkins Laboratory with Eleven, and as a result, she developed the unique ability to create illusions in people's minds. However, unlike Eleven and her friends who are trying to save the world, Kali and her gang of misfits are on a quest for revenge.
When we last saw Kali, she was escaping the police, just as Eleven realized she needed to get back home. And as Eleven parted from her "sister," fans were left wondering if we'd ever see Kali again. Speaking at Vulture Festival LA (hat tip Deadline), co-creator Matt Duffer has revealed that Kali's return is already being planned: “It feels weird to me that we wouldn’t solve [Kali’s] storyline. I would say chances are very high she comes back.”
Yet this can only happen if Stranger Things does indeed return for season 3. While it's likely that one of Netflix's most promising series will be renewed, co-creator Ross Duffer also on the panel seemed hesitant to say either way: "We are [in] very early days on season three and we're still figuring it out." Then after realizing his misstep added, "I probably wasn't supposed to say that… That's not official, that wasn’t an official announcement — we’re just working on it, just for our own amusement…for fun!"
It's no secret that The Duffer Brothers are looking for Stranger Things to last about four or five seasons, but Netflix has yet to confirm the series will be back. Still we can imagine what future installments will look like since the group still has to defeat the Shadow Monster. On top of that is the return of Kali and whether she'll turn out to be a friend or the ultimate foe, along with any other kids that may have survived Hawkins Lab.
