Stephanie Brown is a danger to society

Usually Batman wouldn't be too concerned, he hadn't been... up until they had found video of when the last note dropped. The spy was a teen aged girl. Or at least someone who had the appearance of a teenage girl, it was difficult to tell over the grainy black and white security footage, Batman thought to himself, can't be too careful. Still he was sure that if there was even a chance of her being a teen they would have to approach her. It would not be safe for her to continue this path, especially alone.

Batman meets Stephanie for the first time to try to talk her out of vigilante work and ends up almost falling off a roof three times in less than an hour. Also Stephanie talks everyone's ears off and breaks her Dad's stuff.
