But despite the fact that Nathan is no longer a Cayde-6 expert, he still decided to talk about the robots death with Kotaku, while they were discussing that aforementioned fan film. And he is firmly of the mind that Cayde-6 is alive, and hes got some pretty solid logic backing up his arguments:
"How do I feel about Cayde-6? I absolutely love him. How do I feel about that character dying? I don't personally believe it. He's a Guardian. He should be able to come back. I mean, that's their whole thing, they come back, right? The whole thing is the resurrection."
A good point. You could argue that consistency of video game resurrection is always plot-dependent (IE, not using a Phoenix Down on Aeris/Aerith), but one would like to believe that Bungie would have thought of this ahead of time. So either they did and well get some sort of in-universe explanation, or everyone is in for a massive surprise-not-surprise when he comes back from the dead.
In any case, if you miss Nathan Fillion in Destiny 2, dont worry: apparently hes coming back.
"In that case, my go-to would be, I'm really excited to work with Activision again and do the prequel of how we get to Caydes 1 through 5. Cayde-6 prequel. That's what we need to start talking about right now."
Do we, though? Do we really?
