While researching about a villain's parentage as Oracle, Babs discovered that the Information about Amity Park is blocked (maybe is the GIW, maybe is Tucker or an aftermath of Technus shenanigans in the city).
She realizes that she can't investigate about this random place and get concerned, so she decides to investigate it in person. But since is just a reconnaissance mission to understand the technological block she didn't tell the bats, why would she?
When she arrives there, she saw all the things happening: the teen hero, ghosts invasion, government cover-up, etc.
But that's not the worst part, because she also saw that something was happening with the town hero: He was moving like he couldn't see halfway, stumbling, missing his aim, his coordination was obviously failing and the blind spot was so obvious to her!
So instead of telling Bruce or the League as she should, she decided to talk to him. The boy told her that he had a really bad accident and he still felt the aftermath (like her)
When Babs asked him if he had done rehab to recover and he shrugged saying that his powers had fixed it, she was horrified. It seemed that no one had taken the time to give him rehabilitation therapy, a few days in the hospital and he was considered cured!
The boy also admitted about losing sight in one of his eyes over time, but not doing anything because he felt ashamed about it. The boy thought that this disability made him less valuable in combat, that when he recognized it, he would have to stop being a hero! Babs couldn't help but get annoyed with whoever put such a stupid thought in the teenager's head.
So she made up her mind: She would teach that boy about the good path to recovery, and show him that an accident didn't have to ruin his life, she would teach him to to be proud of his newfound disability, because that didn't stop her from being a hero and it wouldn't stop him either.
