[It wasn't much of a slap, didn't even hurt him any. It did give him information such as the fact that this man clearly had no gun callouses or any to speak of that would indicate the kind of time and practice needed for weapons. That confirmed the fact that, unless HYDRA had some weird obscure breeding program (unlikely), this was not anyone that he knew personally.

And yet, that was definitely his name. It wasn't one that he normally gave out in full and hardly used his first name unless he simply wanted to blend in. He flexed his fingers and finally dropped his hand to his side.]

And you would be? Because I don't know you regardless of your accusations, and I assure you, I'm very good with faces. [He was just as good cutting them off.]
