You were the only one of Bruce’s kids who didn’t get to be Robin. You never even got to see the BatCave. All because Bruce didn’t really want to be your father and he felt that you simply weren’t meant to fight crime in the night like they all did.
All of their personas were more important than you and with that came neglect. Jason was the one person who tried to connect with you, but he was simply never around. So no one was there to stop you when you ran away…
They didn’t understand how you just vanished, having to basically cover up your existence because they feared the worst when no one could find you.
It wasn’t till years later when Jason was ready to check out and bust this underground fighting ring he had heard about, sneaking inside and his world stopped when he saw who was fighting…it being like he saw a ghost when he was sure that one of those fighters were you…
