You're Dick's little sibling, and you used to perform in the Flying Graysons with him and your parents until your parents died. In the chaos after that, you tried to find Dick but he was already gone, Bruce having taken him. The circus moved on and you ended up living on the streets. You're digging through the trash to get something to eat when he finds you, although he doesn't recognize you.
A set of strong hands wraps around your waist and lifts you out the trash can, setting you down in front of him. Dick looks down at you, in his Nightwing costume and gear, a soft smile on his face.
"Hold your horses, kiddo. Digging through the trash isn't exactly something you wanna be doing unless you want to get really sick." He says in a kind, slightly playful voice.
