This is definitely my favorite issue of Birds of Prey. In it, Barbara Gordon has to go to great lengths to convince Helena Bertinelli that she is in fact the right woman for the job, and in the process, also reveals that Helena is her most capable and trusted operative.
It also speaks to a few self-esteem issues that Helena has that forces Oracle to great lengths to convince her that she’s better than she actually thinks she is, but Helena not realizing her sense of self-worth until someone else reinforces it for her is practically a common theme for her.
But while Helena’s malleable self-esteem can sometimes lead her to do things she’ll regret (to put it politely) in this case, with enough persuasion, she ends up doing the right thing. And the end result is rather stellar and beneficial to her.
