In Eternals' post-credit scene, Dane Whitman ponders wielding the Ebony Blade only to be interrupted by a mysterious voice: Mahershala Ali's Blade! He asks if Dane is ready for what comes next, and seeing as the box has an ominous carving that reads "Death Is My Reward," Sersi's human boyfriend might be unrecognisable when we next see him.
Talking to Variety, Kit Harington revealed how much he knew about Blade's MCU debut when that stinger was being shot. "I knew the line that was being said, because it was said out loud and it was in the bit of script that I got," he confirms. "I only knew that was Mahershala’s voice just about three weeks ago. Chloé texted me saying that’s what they were doing. It really excited me, hearing that. He’s one of my favorite actors out there at the moment."
"Up until that point, all we’ve seen is a really good guy that we hopefully like," Harington says of Blade's apparent warning. "I like the idea that this thing is not good for him. With that sword, and what I’ve read about it, what I wanted to capture in that moment was this idea of addiction."
While that line coming from Blade may have been a surprise to the Game of Thrones alum, he confirms Marvel Studios hinted that a team-up with the Daywalker might be in his future. "I had some inkling that there was going to be a kind of crossover there, from early conversations," he teases. "I don’t know what the future is, and I have no idea. There’s nothing written. Nothing I’ve been told."
Director Chloé Zhao, however, was a little more willing to tease the ramifications of this stinger. "All I can say is it does have a very big repercussion on the future of the MCU..."
The Blade movie putting Black Knight front and centre now seems inevitable, and as these two do have a history in the comic books, this unexpected team-up could take us to a lot of very interesting places. Hopefully, Marvel Studios will no doubt reveal more about those plans in the near future.
Eternals is now playing in theaters.
