Matt and Ross Duffer explain their struggle with how to end the series in the upcoming "One Last Adventure: The Making of Stranger Things 5."

Essentially, as the gate to The Upside Down collapsed, Eleven's sister Kali (Linnea Berthelsen) could have used the last of her powers to cloak Eleven in invisibility to help her escape without the kids noticing.
