The unsung heroes.
How many of these people joined SHIELD because when they sat alone at night in the dark after a history lesson or watching a biopic or reading a biography, they asked themselves “if Captain Rogers asked me, would I have gone?” and found the answer to be “yes”? How many people had already had this conversation with themselves, years ago, hashing out their fear and hesitance and ideology with the idea of the man before they ever heard his voice? And how many of them didn’t, how many of them joined up to get out or pay for college or be good at something, how many of them asked themselves the hard questions in different ways or never at all and still found within themselves something that answered?
I’m not into the bulk of the Captain America symbolism, most of the time. But the idea that there is something in people that can rise up and answer when asked not to shoot? That, I’m into.
