One of the moments that sticks out every time I watch Iron Man is that brief second we Tony pitch forward and drops his head onto Rhosey's shoulder. I love it so much because everything about his body language says that he knows he's safe, he doesn't have to fight, because someone he trusts with his life is watching over him. It's important to me that a person so armoured both physically and emotionally has this moment of vulnerability. I love seeing tough as nails badass Tony get to have that kind of security.
