Stranger Things wrapped up at the start of 2026, but Matt and Ross Duffer are still being asked about it. Frankly, they’ll probably never escape their creation, especially with Netflix’s determination to wring every last drop of value out of the franchise. While the finale continues to be controversial (Can we all just agree that Eleven is dead and move on?), the Duffers actually name a much earlier episode as the one they wish they could do over. That said, the episode in question does tie into the big Stranger Things endgame arc. It’s episode 207, “The Lost Sister,” which sees Eleven (Millie Bobby Brown) flee on a side quest to Chicago, where she meets Kali (Linnea Berthelsen), aka Eight, a fellow Hawkins Lab escapee with psychic powers. While there’s some instant trauma bonding, Eleven eventually chooses to return to Hopper and her friends rather than lend her talents to Kali’s revenge scheme. Their clashing approaches to problem-solving resurface when Kali pops up during Stranger Things‘ final season. But speaking to Josh Horowitz on the Happy Sad Confused podcast, the Duffers revealed that if they could go back in time, they’d love to have a “second shot” at crafting “The Lost Sister.”
