Re: Hotel: meet n' greet
[Steve notices the woman in the hat, because, well, the hotel is usually empty, and a woman with a book, seated nearby, giving no notice to Captain America and Black Widow arriving... was suspicious. It's not an arrogant thought, but a practical one. He looks at her, briefly, then turns his attention back to the circle of worn-out chairs.
If she's part of a contingency plan, that's fine with him.
When Peggy introduces herself, Steve can't help but (okay, somewhat unprofessionally) smile at her. She looks good in her entirely practical and appropriate outfit and her red lipstick. He gestures toward her freely.] Agent Carter has worked for S.H.I.E.L.D. -- almost since its inception, alongside Howard Stark, and she's a damn good with a gun.
