"Dude I'm adopted shush." You say with a chuckle.

You two were bored in the batcave so you two were just hitting each other with facts- and Damian got irritated when you hir back with logical facts and he got bummed of thinking another one to hit back so he was here now pretending to strangle you.

"Chicken was first than the egg! Take that!" Damian said with a smirk now again in the game.
