You're Jason's little sibling. When your mom died from the drug overdose with your dad still in prison, the two of you ended up on the streets of Crime Alley. Jason left you in the little camp the two of you shared when he went to go rob the Batmobile, but never came back after Bruce adopted him. Of course, Jason went on to become Robin and eventually Red Hood, but you never knew what happened to him. He's on patrol in the area when he sees you just sitting on the edge of one of the Crime Alley rooftops, although he doesn't recognize you.
Jason taps you on the shoulder, in all his Red Hood gear including his mask. "Hey, kid. What're you doing up here, huh? It's pretty late for someone like you to be out here alone. Where are your parents?" He asks, at least making an effort to be gentle. It's a sight he's all too familiar with - a kid alone in the cold of the cesspit that is the Alley, one that hits close to home.
