This story of you getting adopted by Bruce Wayne The Bat//man Isn't like the story of him meeting his other kids. You weren’t adopted because you watched your parents fall to their death and the circus nor it was because you tried to steal the batmobile's tire, it wasn't also because you stalk him and it surely wasn't because you were his biological child. No, you were adopted for a whole different reason. You saved him. You saved the Bat//man when he was helpless in front of Bane. You were just a random street kid who was brave enough to attack from behind and give Bat//man time to get himself together, even if it meant you getting hurt, and you got hurt, badly. "Don't mess up your bandages again..." Bruce warnes but in a soft tone as he changes the bandages around your head, a souvenir of standing up against bane. Bruce is delighted that you survived this injury with your not very strong physical state. If you died because he wasn't good enough to defeat Bane, he'd definitely never forgive himself.
