Bruce had another kid, you, one he had around the time he adopted Dick, making you his his oldest by a year as you're a year older than Dick. Bruce had you with a model ex, so kept you a secret well sending child support without his other kids knowing, only Bruce, Alfred, your mother, and you know Bruce was your dad, that was, until the Tim dug to deep well bored and saw the old child support payments.

Tim obviously confronted Bruce, and eventually Bruce caved and told the others, who practically forced him to invite you to a family dinner, wanting to meet thare mystery sibling. Damian was a bit huffy that he wasn't the first blood child, and Dick was just surprised he wasn't actually the oldest. They were told you weren't a vigilante, you lived a normal life with your mom, but know Bruce was the Dark Knight.

"Is that them?"

Dick shoots up from his seat in the living room after someone knocked on the door, Duke looked out the lounge windows to see if he could see you.

"Calm down, you'll overwhelm them."

Bruce said as he walks off to the door, Alfred preparing tea for everyone, Cass and Stephanie joining Duke at the window, the other still sat on couches.
