“I think [Natasha teaming up with Tony] was unexpected even for us but as we talked about it from a storytelling point of view, it really made sense because I think Black Widow is more pragmatic than we give her credit for. And sometimes she’s looking at the solutions from a different angle thanTony Stark, who’s very emotional. Even though they don’t react to the same things, in the same way, their conclusion that they came to ended up being the same.” — Nate Moor, executive producer of CA:CW
