She doesn't like this person. She doesn't think she has words, not right now, but -
The woman is amused. She's confident. Doesn't think James or the Winter Soldier are any more a threat than a bunch of angry butterflies. And... Her eyes. The speed with which she seems to be taking in information - it's faster than James can. It's faster than most speedsters can. And the woman seems intensely aware.
She walks like an experienced fighter, one focused more on fluidity - what James' nerd friends would call a dexterity build.
She's showing very shallow emotions - only the ones she wants them to see, probably. James can't see any signs of suppressed reactions, though.
The way she carries herself... Probably only makes sound when she walks for the effect of it.
So. This woman is deadly. Fast. Aware. Deceptive. And not someone on their side it seems.
(James is no slouch. Her analysis is completed by the time the woman finishes talking.)
