You know who he is right? Anyways it just seems strongly hinted, such as: 1. How he didn't know how to fight, like in his original debut 2. He was a kid, about 12 years old like Batman Jones 3. He was a Batman Fan 4. He looks similar to Batman Jones

I'm thinking it's more of an easter egg type thing than an actual appearance though.
