Everything we know about 'Stranger Things' season 3

Warning: Spoilers ahead for "Stranger Things" season two.

Netflix officially announced a third season of its hit series "Stranger Things" on Friday, much to the delight of expectant fans. Though we still don't know when to expect the next installment, nor how many episodes the season will be, "Stranger Things" fans are still celebrating the news.

Why we might get up to five total seasons of "Stranger Things"

In an August interview with Vulture, The Duffer Brothers also revealed that a fourth season is likely. Then executive producer and director Shawn Levy told Entertainment Weekly that there could even be a fifth season on the map.

"The truth is we're definitely going four seasons and there's very much the possibility of a fifth," Levy told EW. "Beyond that, it becomes I think very unlikely."

There was a gap of just over one year between "Stranger Things" season one and two, so fans can likely expect a similar timeline for the next season's premiere. As for what the possible future seasons will focus on, we have to turn to the  Shadow Monster, aka the Mind Flayer.

The Mind Flayer will play a role in the future

Season two ended with the sweetest middle school dance we've ever seen, but then ominously shifted to the Upside Down to reveal the Mind Flayer still watching over Eleven, Mike, and their friends.

Even though Eleven closed the gate to the Upside Down, the monster lurking in the creepy alternate dimension isn't gone. This will spell trouble for the future of Hawkins.

"They've shut the door on the Mind Flayer, but not only is it still there in the Upside Down, it's very much aware of the kids, and particularly Eleven," Ross Duffer told The Hollywood Reporter. "It had not encountered her and her powers until that final episode. Now, it knows that she's out there."

Expect another time jump between seasons

The Duffers also told THR that another time jump is inevitable since the young actors are growing up quickly. The kids were all in 8th grade during "Stranger Things 2," which means they should be starting high school in the next season.

In addition to the Mind Flayer storyline, there was still the open-ended storyline involving Eleven's "sister," Kali, aka Eight. What about kids one through seven, nine, and ten? Did they escape Hawkins Lab too? Are there more out there other than Eight/Kali? 

All of these questions and more will hopefully be answered on the seasons to come.
