Bruce and Damian were taking out thugs together. It's what Batman and Robin did. Take out criminals. And Damian as he got older was getting so good at it.

They were currently fighting some mob guys before a female player came out, dressed in all back. Kicking Bruce's ass. And Bruce pinned her and was going to knock her out before he was stopped by Damian.

"Father! No! She's your daughter! My twin sister!" Damian shouted.
