Marvel Studios’ Eternalsfamously ended with a post-credits scene that introduced Harry Styles — as Thanos’ brother! — into the Marvel Cinematic Universe, a loose thread that hasn’t been addressed since the film was released in 2021. There was, however, another post-credits scene that teased a heroic future for Kit Harington’s Dane Whitman. This thread has also gone completely ignored by the MCU, and Harington has revealed that this won’t be changing anytime soon.
