Netflix has released a teaser trailer for Stranger Things Season 4, which seems to suggest that the upcoming episodes will reveal more about Eleven’s backstory.
The minute-long teaser appears to be set in the laboratory in which Eleven was experimented on. Numerous children can be seen playing with toys as they are observed by a scientist through a camera. All are dressed in gowns similar to the one worn by Eleven back in Season 1.
Eleven, are you listening?
