This right here. Joss Whedon writes women who are real, who have weaknesses and hopes and fears and flaws but at the end of the day they push past all that and they’re badass anyway (see: Buffy, Willow, and Faith in BTVS). Courage isn’t not being scared, it’s being scared and doing what you know is right anyway because it’s right. Everything is a clusterfuck in this moment and she doesn’t have to answer, she can run away and hide, she has the skills to disappear but she made a decision to be one of the good guys, and even if she hid until it was mostly safe then slipped back to the control room, no one would have noticed, she could have said she was busy doing something else, she’s a master at lying. She didn’t. She is literally shaking with fear because she was almost killed by a huge impossibly strong mutated rage monster that could break her in half but she hears that she’s needed and knows that she can take out Hawkeye and help get something else under control so she pulls herself together with a deep breath and goes where she’s needed and gets shit done. Natasha fucking Romanoff.
