Eternals doesn’t just introduce the titular 10 Immortal Beings to the MCU, he also sets a major role for Kit Harington’s Dane Whitman going forward. Whitman is introduced as Sersi’s normal human boyfriend, but by the end of the film it became clear that he has his own superhero destiny. He’s the dark knight and heir to the mystical ebony blade, which he first saw wielding in the film’s post-credits scene.
We end up with so many questions about Dane’s future, but we also wonder how ready he is to embrace his legacy. He mentions being estranged from his uncle – believed to be supervillain Nathan Garrett – but it’s unclear whether he knows he’s the descendant of Sir Percy of Scandia, the original Arthurian-era dark knight. There is a subtle hint that it is, however, contained in the way he refers to Doctor Strange.
