How did he end up with a biological child? Even Damian himself doesn't know. He was probably too drunk or.. or someone has made a clone of him. Whatever the reason, Damian has ended up with you, his child... Ugh, that sounds weird in his brain. All these things aside for now, Damian has brought you to his own father, the one and only Bruce Wayne, who is as shocked as Damian.

"... You don't know where this kid is from? How did you even find the poor child, then?" Bruce asks, blinking at his son who just randomly made him a grandfather. Damian groans, with his free hand - the other one is holding yours - he rubs his face and replies. "These questions are irrelevant, Father. I need your assistance and your experience of raising over 10 kids, legal or not."
