'Stranger Things' Star Sadie Sink Reveals Unexpected Theory on Eleven's Fate

Netflix's iconic and most-watched series Stranger Things officially came to an end on New Year's Eve with "Chapter Eight: The Rightside Up."

(SPOILERS)

In the series finale, Eleven remained in the Upside Down after defeating Vecna - at the suggestion of her "sister", Kali and in an attempt to keep her friends safe. A time jump after her sacrifice suggested that El was dead, but Mike chose to believe a story that she found a way to survive and remained hopeful she was living somewhere away from Hawkins.
