It wasn't long before members of the beloved season one cast weighed in. Shannon Purser, who portrayed Barb, tweeted, "We've finally been renewed for Season 2!!! So happy for my fellow cast! Hope to see them again soon."
Her tweet sparked rumors that her character, who was -- SPOILER ALERT! -- killed off by a Demogorgon, may be making a return -- or, at the very least, perhaps getting proper "#JusticeForBarb."
"Sorry guys, I'm as much in the dark about s2 as you are," Purser clarified. "I say 'we' because the cast/crew have become a bit of a family for me. So proud."

Gaten Matarazzo, who portrays Dustin, also opted for an Instagram video, thanking his fans for their constant support.

"Hey guys, I just wanted to be the first to tell you, they have officially announced season two, I'm so excited," he exclaimed. "I am so excited, guys! Thank you guys for helping me out with this. You guys have helped the whole cast, the whole company -- without you guys, I couldn't do any of this."
As for what's in store for season two, show creators the Duffer Brothers are staying tight-lipped, but did tease a few interesting tidbits during a recent interview with Entertainment Weekly.
"I don't think we ever thought anthology," Ross Duffer explained, in regard to their decision to continue the story in the year 1984. "I think we talked like a larger time jump where the kids are older now and it's a different decade. That's something we batted around from the very beginning. But for us, there's still more story here [in the 1980s], there's still things that are unresolved."

While fans can expect the return of Matarazzo, Finn Wolfhard (Mike Wheeler) and Winona Ryder (Joyce Byers), they're leaving one character a surprise. "We don't know about Eleven," they dished. "We leave that up in the air."
That being said, the Duffers revealed there's a lot to look forward to, including four new characters and nine episodes (one longer than the previous season). "There's going to be a lot of new and interesting dynamics that we didn't see in season one," Matt Duffer confirmed.
Season one was set in the small, quiet town of Hawkins, Indiana, and although that's where most of the action will be taking place the second time around, the show creators also confirmed "we will venture a little bit outside of Hawkins."
"I will say the opening scene [of the premiere] does not take place in Hawkins," Matt said, adding that they want to go further explore the series' alternate dimension. "We kinda just peeled back the curtain and revealed a tiny bit of the Upside Down. So we definitely want to explore a little bit more. There's a lot we don't know about the Upside Down at the end of season 1."
"We obviously have this gate to another dimension, which is still very much open in the town of Hawkins," Ross added. "And a lot of questions there in terms of, if the Monster is dead, was it a singular monster? What else could be out there? We really don't go in there much until they go in to find Will at the end. So we've opened up this doorway, and to us it's exciting to talk about, like, what else is behind there? There's a lot more mystery there to be solved."
