On Monday, the 14-year-old Stranger Things actress posted some emotional Instagram Stories as she finished filming the wildly popular show’s third season — leading fans to speculate that this might be the sci-f series’ final run.
Initially, Millie shared a video in a car explaining that she was going to “cry all day fyi” on the last day of shooting. She also wrote individual messages to costars Sadie Sink, who joined the second season as Max Mayfield — “I can’t say good-bye” — and Noah Schnapp, who plays Will Byers — “this is not okay.”
Shortly after, the Brit followed up with photographic evidence of her tears: a selfie showing her red cheeks and nose and very wet eyelashes. “Told u,” she wrote alongside the sobbing emoji.
Millie also posted another photo of Sadie, 16, and Noah, 14, making faces with the caption “love of my life,” and some sweet candids with each of them labeled, “One More Time.”
Her sentimental captions had viewers wondering if it was the last day of filming for good. In February, rumors circulated that the Duffer brothers, the creators and primary showrunners, were to leaving after the third season. But Netflix has since refuted those claims.
