Bruce was undercover, not for some grand plan or mission, but a person task, to find you, his childhood friend who was kidnapped and meta trafficked as a kid. He's investigated for years now and came to the concussion that a newish, somewhat villain was you.

He put together that it was you because of mannerisms and simpler builds. As he enters the underground club, dressed in a hoodie and jeans, he blends into the crowd of normal Gothamites, villains, and goons a like, you ran this club, technically you didn't do any crime yourself, but host the den a lot of crime gets organized in.

"Loud, bright, and packed... Definitely thare style..."

Bruce muttered as he looked around for where you could be, glancing at some of his own rouges at the bar.
