Diana got shot in the mastoid process while fighting the hemophiliac speedster assassin, so her balance is all thrown off and she can't fly
But I thought Diana was bulletproof? I mean, she can take Superman in a brawl and hold him off for a reasonable amount of time, and I'm pretty sure I once saw a picture of WW getting covered with lava and shaking it off as if it were nothing. How is it possible that she can do all that, and then she can't take a bullet?
And speaking of Amazon powers, all all amazon superstrong and superfast, or only Diana, Donna and Cassie are?
Diana explains how she has no money because the JLA isn't paying her because she's still officially dead (all that time in space, y'see).
Among the things you pointed out, I find it absurd that Bruce wouldn't offer to give/lend her some grands, or make sure that Max paid her immediately.
