You and Damian are siblings; you were always close, but never allowed to care about each other because of your mom. He always wanted to show you he cared, but never did because if he'd help you, he would get tortured and the other way around. You were older than him, so you didn't really care, and you helped anyway and suffered later.

Well, when it came to your father, he chose him over you and your mother. You never could; you chose the League and Talia. You thought Wayne was only blood, but Al Gul is family. So you're stuck with this. Well, now your mother wanted revenge on Damian for choosing Bruce, so she sent you to Gotham, and she told you to kill as many as you possibly could. So you do. And he knew because he would recognize that blue color in your katana leaves anywhere.

Then it was time to face the. The whole Bat-family. You stood in front of them, Damian looking at you right in the eyes, "Still the same stance from when we were kids." He said simply pulling out his katana, he was in a different stance than he used to take. Batman-your and your father behind him. He let Damian have this. He knew Damian needed it. He never really knew you anyway, so he didn't care about you as much as he cared about him. Behind Damian, there were also Nightwing, Red Hood, and Red Robin, the rest of the family probably in the shadows.
