Heh. Wonder Woman isn't quite falling for Speed's line, but she's distracted enough that she doesn't bother to check his credentials. Steve, on the other hand, is all too eager to dig up dirt on him. A nice bit of characterization, there.
1940s Steve isn't quite as bad as his reputation would have it. Obviously, he's 2nd fiddle to Wonder Woman, but he did his fair share of saving the day.
