I think that's all it is. Essentially secret SHIELD technology that's an abomination to man and God.
The question is, is that "man and
God" or "man and
god"? I took it to mean the second way.
I honestly don't follow. I mean I get that you capitalized one and not the other, but I otherwise don't know what you're talking about. Although, if it helps, I meant it as a figure of speech.
That's what I'm thinking. Again with the "man and God" and "moved heaven and Earth" comments, it seemed to me that they were implying alien-tech, Asgardian or otherwise.
Did they say man and God or just me? I thought I said it. The technology might be extraterrestrial in origin (probably not Asgardian given a) I don't think Asgard has been shown to have anything like this and b) the relatively small connections between Asgard and SHIELD, limited to pretty much Thor), but it seems to be an original invention for the television show. However, SHIELD is portrayed as collecting the weird, strange, and unexplained from both our planet and outerspace with no hesitation to try to use it for their own purposes. Given that, it could certainly be alien or simply invented by a mad scientist.
To be honest, it was a legitimately powerful moment on its own that can stand on its own two feet without needing to steal something from a comic. And, to be honest, I don't think there's anything like this to steal. Many comic explanations didn't explain the whole "he can never know thing" anyway. A Life Model Decoy would have worked (I find the whole "am I really me" debate to be a bit tiresome these days, though).
The only one I could think of is something involving "Death" the character. But Marvel, while is has fantasy, hasn't been fantastical so far and I doubt the show would be where they take the leap to go that far. Maybe after Dr. Strange, we'll be able to go down that route, but I don't think we're there yet. Keep in mind how much the first Thor movie (the second to a much lesser degree) had to emphasize that they were just aliens not gods. That's because Marvel thinks the audience can accept aliens, but won't accept gods. Likewise, I don't think they're prepared to introduce death unless they can think of a way that would make her just an alien and that would probably cheapen death too much to be a good thing.
Yes, it is. My question is: Is it just a figure of speech or is it a hint of something more?
Well, I've been only giving my opinion, but I thought it was pretty clear my answer was, yes it's just a figure of speech, no it's not a hint of something more.
