Eternals: Who is Dane Whitman and What is his Family’s Secret?
In Eternals, Dane Whitman, portrayed by Kit Harrington, is the boyfriend of Gemma Chan’s Sersi who is a teacher. However, he came across the ex-boyfriend of Sersi, the Eternal, Ikarus, who is played by his Game of Thrones co-star Richard Madden. While he did not appear that much in the whole movie, he showed the human life enjoyed by Sersi. By the end of the movie, Dane and Sersi get back together and when he is about to mention to her that there is a family secret that he would like to look into but he was interrupted when Sersi was taken by Arishem. In the post-credits scene, Dane Whitman is alone in the room while he is contemplating with what is inside of the family crest. Even when he was quite hesitant at first, he opened the case and there, he found a sword which has the words “death is my reward” inscribed on it. When Dane was about to touch the sword, it cuts to black and a voice says, “Sure, you’re ready for that, Mr. Whitman?”
It turns out, it is the voice of Blade as confirmed by Chloe Zhao, and the sword picked up by Dane Whitman is the Ebony Blade, one which Black Knight could wield. The first one to use it is a servant of King Arthur going by the name of Sir Percy and the reason why Dane is close to the sword is because the second wielder was his uncle, Nathan Garrett, his uncle who became a villain. The Ebony Blade was forged from a meteorite with a magical enchantment making the user invulnerable to magic and it can cut through anything but the cost of it is a curse that comes with it which could turn anyone to a ruthless killer. Blades connection is nothing random, in the comics, a fake Ebony blade was created by Dracula, a known villain of Blade. See Dane Whitman in Eternals, now available to stream on Disney+.
