While I feel that a great portion of Natasha's character is that she doesn't make close ties or make them easily, instead situating herself carefully outside of things to maintain a control, I almost feel as if...she's TOO outside of what's happening.
She is a formidable source of information and a very large asset to the Marvel crew AND the town itself. I would really like to see her utilize this in her widow-like way (i have seen and appreciated her jokes, sarcasm, and sass). I do realize she's coming off of Cap 2 and you have nothing to go on when it comes to her approach now (thanks a lot marvel) but still.
