Stranger Things is back for its final season, and there's a new face in Hawkins—Mr. Whatsit, Holly Wheeler's imaginary friend.
While most people think he's just in her head, Holly insists he's real.
The surprise? Mr. Whatsit turns out to be Vecna in disguise, making things even tenser when Holly gets caught by demogorgons.
