jl eh?

Was rewatching the Snyder 'cut' of Justice League in preparation for The Flash and still can't get my head around this scene:

"What are your super powers again?"

 

"I'm Rich"

 

But I thought his name was Bruce, is Rich his middle name or is it Bruce his middle name and he just prefers it? 

 

Or is Rich his other alter ego? 

 

Was he born Bruce, became the Batman and then realize he was Richard all along. 

His name Rich being his superpower in a kind of an homage to the Superman/Kal-El/Clark trichotomy?

 

Anyone?
