‘Stranger Things’ Season 2 Air Date, News & Update: Eleven S2 Surprise From Duffer Brothers? Upside Down Return Filming Started?

"Stranger Things" Season 2 fans waiting for news on the Netflix series details from creators Matt and Ross Duffer are in for an Eleven (Millie Bobby Brown) surprise in S2. Matt and Ross Duffer may be making good on that plan to put Eleven and Hawkins Police Chief Jim Hopper (David Harbour) together in "Stranger Things" Season 2 as previously revealed.

While "Stranger Things" fans were shocked when Ross Duffer told Entertainment Weekly that S2 casting may not include Eleven, the Netflix series will be bringing back its biggest star. For one, Variety cited Matt Duffer on the potential of putting Police Chief Jim Hopper and Eleven in future episodes of "Stranger Things."

  In recent news, Movie Pilot cites David Harbor in his appearance at AOL's Build Series where Chief Jim Hopper gave Eleven fans hope for "Stranger Things" Season 2. According to David Harbor, the Duffer brothers could not have developed Eleven into as huge a character in the Netflix series if the "Stranger Things" star was not coming back.

Eleven gained instant Netflix fandom when introduced by "Stranger Things" as a mysterious science experiment on the run. Eleven gained even more popularity when the Netflix celebrity ended "Stranger Things" Season 1 with an ultimate self sacrifice to save her friends and Hawkins from the demogorgon of the Upside Down.

  The scene that ended the demogorgon seemed to have also ended the existence of Eleven in "Stranger Things" Season 1. Devoted "Stranger Things" fans, however, believed that a twist in S2 of the Netflix series will reveal that Eleven is well and alive.

Eleven revelations and "Stranger Things" Season 2 surprises from the Duffer brothers should be right on schedule. Screen Rant cites buzz that the Netflix series has begun production work to take "Stranger Things" Season 2 back to the Upside Down.

Netflix is slated to release "Stranger Things" Season 2 come 2017 - firm date still pending. What twist would you want "Stranger Things" Season 2 to bring about Eleven, Chief Jim Hopper and the Upside Down.
