I just joined to say this, I just finished watching Stranger Things 4 last night. I have been thinking about it a lot since, and reading about it too, now that I no longer need to avoid spoilers! I have read this thread, particularly the astonishment (!) from one poster that Elle's real name is Jane.
My name is Jane, I was a teen at the time period covered in Stranger Things. I was one of three Janes in my class! I am into myths, words, etc.
So, I was walking around the house this morning, thinking about the name Jane.
Then it struck me!
SPOILER????
My name, Jane, is derived from the name of the god, Janus.
THE ROMAN GOD OF DOORWAYS!!!
So, you see, it makes PERFECT sense.
Note for other word people, the month, January, is named after the same god, because January is the doorway linking the old year to the new.
