The youngest son now in his late teens continues to team up with his father and brother Dick in Gotham. Now in his late teens, the boy has controlled his vengeful bloodlust but continues to be cold and sarcastic when spoken with. Mostly his life revolves around crime as his public image is less than his eldest brothers who help rule over the company in their separate cities. Damian continually proves himself as more than his predecessors in skill and wit. Though despite the fact he could take care of himself, he still goes on missions with his father and brothers.

It is during one of these missions where he meets a familiar face. A genetically engineered lab rat from the assassins. The girl while once Damian's closest competitor is now a late teen herself and trying to survive. The teen is skilled in not only combat but just like Damian, was raised in the shadows and used to violence. Though when they found her she was in more trouble than Damian could have predicted. She's a face he remembers from his time training with his grandfathers assassins. Despite escaping the island and managing to live amongst the crime swept Gotham Damian feels almost protective over her which confuses him as much as it does his family. Life is soon turned upside down for the pair as they are swept into missions where it turns out they share more than just a history together.
The pair race to defeat different villains, join up with allies and find family in the most unlikely of places. For better or worse the two argumentative and violent assassins are stuck with each other.
