No sooner did Netflix confirm a second season of "Stranger Things" than executive producers Matt and Ross Duffer began dropping a trail of breadcrumbs leading viewers back to Hawkins, Indiana, and the Upside Down.

Speaking with Entertainment Weekly, the Duffer Brothers revealed that although they'd toyed with the idea of a significant time jump in Season 2, they opted instead to remain in 1984. “There’s still too much story here [in the '80s],” Ross Duffer said.

That means we can expect the return of Mike, Dustin, Lucas and Will in the coming season, along with their family members, presumably. However, the executive producers weren't quite so forthcoming about the future of fan-favorite Eleven. “We don’t know about Eleven," Ross Duffer added. "We leave that up in the air.”

The cast will expanded by four in the second season, although virtually nothing has been revealed about them. There could be an interesting hint to one of the characters, however, in the teaser trailer for Season 2. Throughout the trailer, what seem to be titles flash up among the show’s trademark neon letters. There are nine in all, which coincides with the episode order. If those are indeed episode titles, then the one named “The Lost Brother” could hint at a possible new character -- perhaps another "family member" from Hawkins Laboratory.

Another interesting update from the Duffer Brothers is that the entirety of the second season won’t take place in fictional Hawkins, Indiana. But even more interesting is that both brothers are eager to return to the Upside Down and explore it more fully. A number of questions were left unanswered at the end of the series, most of which concerned the Upside Down and the Demogorgon itself. The Duffers said there will be a return to the “Vale of Shadows,” and they promise fans answers.

The brothers also expressed a certain amount of trepidation toward making a second series. They treated the first series as if it were a "very long film," and that would make any second season, by default, a (dreaded) "sequel."

“I know movie sequels get a lot of shit, but the ones we look up to aspire to pivot and do something different," Matt Duffer said, singling out the work of James Cameron on "Aliens" and "Terminator 2."
