I missed this when I saw The Winter Soldier. Natasha grabs Steve and pulls him away from one stream of bullets and then proceeds to shove Sam out of the way of more bullets with her foot. <<< Yet another demonstration of Black Widow's awesomeness.
My name is Natasha Romanoff. I'm look to be in my mid-twenties, but I was actually born circa 1928. I am know as the "Black Widow" in the Avengers. I'm a kickass fighter, who excels in really any type of combat.
