Father?

Yes, Damian, I said as I turn around in my chair.

I have you seen Y/n, I want to take her to the park, Damian asked?

She is around here somewhere. I just saw her couple of minutes ago, I said.

What are you doing Father, Damian said as he looks up at the bat computer.

I was looking up your sister real parents, Bc I haven't told her that I'm not her father, I said .

Ik that y/n is adopted. But I don't care if she isn't blood. She is a Wayne and I'm her big brother Father, Damian said.

Yeah. She is a Wayne, I said.

I was surprised at you. When I told you and the other's that Selina and I were adopted a little girl. I was a little worried about you and how you would react to y/n since Catwoman is her adopted mother, not your mother Talia, I said.

At First. I was hurt that you adopted another kid, but Ik that you love Selina, It doesn't matter at all. She is my baby sister, Damian said.

Daddy?

Hello My favorite Bat, I said.

Hey, Damian said.

You look at your big brother with a smile.

I chuckled.

Do you want to go to the park with me, Damian asked?

Yes!

Go ahead. I will meet you upstairs, Damian said.

You run happily out of the bat cave.

I thought that you were going to tell her, What happen, Father, Damian asked?

She looks so happy. I couldn't ruin that by telling her that I'm not her father, it would kill her Damian, I said.
