Picture this: a scenario where the JL doesn’t know Batman & Robin’s secret identities yet. Maybe they don’t even know if Robin is real or just a rumor online. And they’re discussing a time for their next meeting when Batman just interjects:
“Saturday won’t work for me. My son’s baseball team is having a bake sale.”
The entire room goes silent, because no one realized Batman even had a kid. Or went out in the daylight.
“What?” one of the others asks, still shocked.
“A bake sale,” Batman says slowly, like they’re all a little stupid. “It’s a fundraiser.”
“I know what a bake sale is! But since when do you have a kid?”
“Have you not met Robin?” he asks, sounding genuinely surprised. “He’s been to the Watchtower several times now.”
“Robin’s your kid?” gets asked first, followed closely by someone else asking, “Robin is real?”
“Can’t you just drop him off?” Superman asks, trying to calm the situation.
“Well I’m also the coach, so that probably wouldn’t be setting a very good example for the kids, Superman.”
“You’re the coach?” Someone asks.
“Of a little league team?”
“Are we in the Twilight Zone?” Hal whispers to Barry, who shushes him.
“Will Sunday work?” Superman asks quickly, wanting this to get resolved.
“So long as it’s over with by 4pm.”
“I told Robin I’d take him to the Gotham Knights game.”
Everyone’s heads are spinning. Batman is actually acting like a normal guy with a normal kid. This is not at all what they imagined he was like outside of the cowl. Some of them didn’t think he ever actually took the cowl off at all.
That Sunday, Bruce Wayne and Dick Grayson are seen on TV arriving a little late to sit behind home plate at the Gotham Knights game. Dick, 9 years old, looks very grumpy about being late until Bruce gets him a giant ice cream to make up for the fact that his meeting ran long. It still takes a few years before the JL find out Bruce Wayne is Batman.
