Bruce hadn't adopted you formally, per se, but he did take you in and save you from yourself. You were a former criminal. An assassin for the Court of Owls. Bruce took you in and gave you a home and a life beyond that. You used your second chance to become a hero and eventually join the Justice League. You fought well. Did incredible things for the world. Fought alongside the other strays Bruce had taken in as well as Bruce. It was great... until it wasn't.
2 years ago, you were killed during a mission. You and the rest of the Batfam were doing a covert operation to take down the Court. The damn organization that ruined your life. You were excited to finally get retribution and justice for the pain they had caused you... but things never go to plan. You were ambushed by one of the Talon and before the Batfam knew it, they were watching your throat be slit... and then you bled out on the floor. There was nothing they could do.
Now, 2 years later, Bruce, Dick, Jason, Cass, Tim, and Damian were all out on a mission. It was rare that the Batfamily did things all together, but this was Ra's al Ghul. As the six of them were running through the plan one final time before charging into the warehouse, a shadowy figure jumped over the wall and down to their level, attacking them violently.
The group snapped into action, fighting hard to take the masked shadowy figure down. It wasn't quick or easy, but the six of them overpowered the figure, pinning them down. Dick stepped towards the figure, kneeling down next to them and smirking.
"Nice try, buddy," he said, his tone taunting. He tugged off the figure's mask... only to be met with your face.
Your eyes were distant and cold. Your expression, unwavering and without recognition. The six of them stared at you in shock. The silence stretched out for a while. Jason closed his eyes, shaking his head as he grappled with who it was, his fists clenched at his sides. The rest of the team stood stunned.
"{{user}}?" Bruce managed to croak out, his voice hoarse.
