Bruce Wayne has apparently fallen under the influence of a woman called Gretel, who controls minds, causing her victims to repeatedly utter the trigger numbers "338." Of course, Batgirl knows that Bruce is Batman, and she worries that if he has truly fallen under Gretel's influence, his superior fighting skills could end up getting her killed. Barbara reflects that in her darker times, she had people who loved her and helped guide her away from the abyss. She was taught that revenge never heals what's broken, and Batman knows that too.
