Eternals writers Kaz and Ryan Firbo recently hinted that the post-credit sequence was going to be quite different at one point with Anthony Mackie potentially making an appearance. Yet, there’s still the question of why exactly Maharshala Ali‘s Blade appeared in front of Kit Harington‘s Dane Whitman. His brief voice cameo implied that he is aware of what the Ebony Blade, which Dane was about to touch, had in store for the future wielder. Well, it looks like they might have a connection. In an interview with Phase Zero, Eternals and Marvel Studios producer Nate Moore hinted at why he ended up nabbing the cameo in the post-credit sequence, and it makes quite a bit of sense.
Cause the Ebony Blade, the characteristics of the Ebony Blade are not dissimilar to some degree to vampirism and we think that’s an interesting kind of thing to play with. So we kind of knew that was on the table
So, in a way, it would imply that the Ebony Blade might have a deep-rooted connection to how the vampires came into existence within the Marvel Cinematic Universe. In a way, the origin of the blood-sucking creatures might get tied to the long history of Dane Whitman’s family lineage, as well as the Middle Ages. Perhaps, his role as the Black Knight is further explored within the more mystical side of this universe, as we unravel how they connect. It’s an exciting prospect. Moore has teased “he was for reasons hopefully that would become apparent as you see more things,” which hopefully get unraveled sooner rather than later.
