I think this is for the video game, and so it's not the usual origin story, or not exactly what I'm used to anyway. Still, it's fairly solid, despite the whole 'knowledge could get a young girl into trouble,' aspect.
And yeah, being Batgirl could get her into trouble, but it could get a younger Bruce Wayne into trouble. So if it's okay for him, why isn't it for her?
Which is why I definitely think this could have been much better.
