Gordon protecting Batman's identity
Ok. Is a well known fact that Jim Gordon probably knows Bruce Wayne’s Batman, but he never says anything because A) he can’t prove it. B) he secretly likes Bruce.
For that reason, he also keeps away everyone who’s getting close.
“Hey, have you guys realized Bruce Wayne’s always out of town while Batman’s missing?
"The guy’s a business man, Carl. Stop being so paranoid”
“Hey, Bruce Wayne adopted a new kid around the same time the new robin came around.”
“Yes, ‘cause Robin is the only black haired twelve year old in Gotham, Frank. Use your head son!”
“Sir, have you ever realized Batman appeared in Gotham the same year Bruce Wayne mysteriously came back after years missing?”
“It was not the same year, Sara. Bruce Wayne came back in December and Batman only appeared the the end of January. Big difference.”
“God, Jim. That Nightwing kid looks a lot like your daughter’s boyfriend…”
“Is it my fault the girl inherited my good taste? Besides, they don’t look that much alike, Dick’s nose is bigger”
“Commissioner, I think I saw Bruce Wayne’s butler passing him a cape and cow under a table during yesterday’s gala…”
“Rich people are weird. Who am I to judge?”
