Halloween is just around the corner, and the second season of Netflix's thriller sci-fi series, "Stranger Things,"  has got everyone covered. The final trailer, which was released by Netflix on Oct. 14, confirms and debunks some of the fan's theories on the show. Moreover, a small detail teases what could be a reunion between the show's superhero and her mother. 

The good news is that Eleven, played by Millie Bobby Brown, is alive and will be back with her telekinetic powers to help fight monsters. However, it fans found it more interesting to note a minor detail that supposedly hints of Eleven's reconciliation with her mother. The video showed Eleven at the door of mother's house.

Episode 6 of the first season of "Stranger Things" had Chief Hopper (David Harbour) and Joyce (Winona Ryder) visiting the house of Terry Ives (Aimee Mullins) in an inquiry about the connection she had with Dr. Martin Brenner (Matthew Bodine) and the Hawkins National Laboratory.

Hopper stumbled upon an article reporting Ives' filing of a case against the doctor and the facility for experimenting with her and her unborn child during her college days. For five years, Ives did not say a word about the injustice she suffered after the research facility claimed that she had a miscarriage. Ives back then asserted that she had given birth to a girl with special abilities, whom she called Jane. All of this was narrated by Ives' sister, Becky (Amy Seimetz).

Eleven's scene in the door was compared to Hopper and Joyce's frame as they were heading out of Ives' house. The interior looked the same, sans some of the flowers and frames. So fans are expecting this season to be more revealing of Eleven's background story, who her parents are, and how she got her abilities. Aside from this, the season will delve into Will's (Noah Schnapp) story after he got out of the Upside Down.

"Stranger Things" season 2 will premiere on Friday, Oct. 27, on Netflix.
