SPOILER ALERT: If you’ve seen The Eternals in theaters or on Disney+, you’ve undoubtedly seen Kit Harrington’s post-credit scene. In it, we get a glimpse of Dane (Kit Harrington) in the presence of a large Game of Throne-like sword, and then a powerful voice calls him by his full name and heeds a warning.
Dane’s last name is Whittman, and Dane Whittman is the Black Knight.
If you can’t wait until Eternals 2 to find out more about this mysterious Marvel character, you can read Black Knight: The Fall Of Dane Whitman on Hoopla.
