Last summer, Stranger Things debuted on Netflix with its first season of only eight episodes. There were some thrilling episodes, and the show left us wanting more. Even though it seemed more like a very long movie with an ending, Stranger Things will come back with Season 2 to explore more of the fascinating world created in Season 1.

In an interview by Collider, director Shawn Levy talked about the way Eleven’s return leaked right before they wanted to reveal it in an “upside-down” way.

We are filming in Atlanta again. I feel like that's how the Millie Brown [return] leaked because someone saw her trick or treating in Atlanta. I was so bummed about that because Netflix had this really clever idea of taking a picture at our table read last week and posting it upside down, which is what we did. But then like two days before our clever idea got to debut, a bunch of places were reporting that Millie was gonna be a part of Season 2.

Season 2 will bring new characters, but will stick to the core group, a group that is now changed and trying to live their lives normally after all that has happened. Levy doesn’t say where they will pick up the story, but he emphasizes the changes that will come with new characters and old characters going through change.

I'm not gonna say how much time has gone by. It is not the next day, I'll say that. And there are several new characters who I think several of them are going to be new fan-favorites because they're great, great new characters. But we are definitely sticking primarily with our core group, and what is different, how are they changed from the experience of last season"¦ maybe “normal” is never possible again. Will Byers was in that Upside Down for a while. So Season 2 is about this determined desire to return to normalcy in Hawkins, in the Byers family, in that group of friends, and it's the struggle to reclaim normalcy and maybe the impossibility of it.
