Last week, we reported that fans would be returning to Hawkins, Indiana soon, following the announcement of Stranger Things seasons 3's wrap in production.

While we were beyond excited to see the season's wrapping, one cast member's post turned everyone's world upside down.

The post in question was Millie Bobby Brown's Instagram goodbye to her friend Sadie Sink (who plays Max in the show,) which left many fans to speculate hints of the third season.

"as we said goodbye, i gave my best friend the biggest hug and told her i loved her so much," Brown captioned her post. "My sister forever @sadiesink_."

While it doesn't explicitly say anything about the show ending or one of their character's not returning for a season 4 (if that happens), it did leave fans to wonder why the post sounded a little cryptic.

In an appearance at last night's Late Show With Stephen Colbert, Brown clarified that the post may have been taken out of context, saying that it wasn't her goodbye from the show, rather, it was just a goodbye to the season:

"[It was] on the last day of the season, not the show," she clarified.

Brown then continued by saying: "I'm just a very emotional person. When it comes to my closest people, like, I'm not good at goodbyes," she revealed. "Everyone knows that... it gives me serious sadness and anxiety."

Talking of the actual post itself, she explained that she just "broke down" when the time to say bye to Sink came. She also mentioned another important group she had a hard time parting ways with catering.

"Also, catering, ugh, that was a tough one. Yes, catering, duh...It's an emotional time."

We've got to agree with Millie, it's a very emotional time.

But, we're glad that it appears all of our favorite characters are safe from the Demogorgon's...well, at least until season 3 officially airs on Netflix.

Watch the interview below:

Stranger Things season 3, what we know so far: 

It was recently revealed in an 80’s style commercial that the show will be getting a new hang out spot for the kids and teens of Hawkins, Indiana. The new spot will be a mall called Starcourt Mall, where you’ll find the “cool kids” frequenting.

What’s more? The mall was announced to be opening in “next summer,” which means that we can only assume the new season will come then.

We also know that the cast will be adding three new characters into the Hawkins mix—an “alternative girl,” Cary Elwes playing the Hawkins mayor, a “handsome, slick and sleazy” ’80s politician and Jake Busey playing a local journalist with “questionable morals.”

It was recently reported that the show is set to be “much darker” than in previous seasons. According to Producer and director Shawn Levy the show will go to some darker places than we’ve seen:

“[It’s] definitely going to get darker still, places that I think audiences are going to really love,” Levy revealed. “It’s got so much heart and humor.”

While we’re stoked about all of the Stranger Things’ news, the best news of all is that our favorite dad Steve Harrington (Joe Keery) is set to have a bigger role in Season 3.

“We’ll definitely get to see some more of Steve Harrington in Season 3, and I’ll just say we won’t be abandoning the Dad Steve magic. I don’t want to say much more, but I literally feel that we were walking along and we stumbled onto a gold mine with Dad Steve,” Levy says.

Additionally, a report from Screen Rant found that Netflix and Century Books have partnered up to officially release the world’s first Stranger Things companion guide of the show called “Worlds Turned Upside Down.”

In this companion, the show’s third season is teased, and it promises that one tentacled monster will be returning to haunt the kids of Hawkins, Indiana once more: The Mind Flayer, the monster that came for, and possessed, Will’s body in season two of the show.

“The Mind Flayer hasn’t lost interest in Hawkins either. The tentacled creature continues to loom near Hawkins inside the Upside Down, and its malevolent influence isn’t absent from the new season,” the book reads. (via ScreenRant)

The third season of Stranger Things is set to debut sometime in 2019.
