Steve: If it’s not the vicious thugs who call themselves heroes today, reminding me how outdated are my old man ways, it’s the amazing inventions that stem from Tony’s mind. Tomorrow’s dreams made real.

Tony: I feel like a snail or a tortoise, lumbering along in my shell, whenever I’m with Steve. So clumsy and so safe, next to his grace and daring.
