Stranger Things season 4: The American is Eleven’s fellow test subject from Hawkins lab?

In the character of Doris, the actress says: “They need your help up on three, something about weird noises coming through the ceiling above some of the rooms”.

This could be a huge hint at the return of the Mind Flayer in season three, but with the Upside Down clip this is sure to have greater meaning.

Could the new season see Hawkins Middle school in the Upside Down?

Stranger Things seasons 1-3 are available to stream on Netflix.
