you were Thomas Wayne's Robin. You were a girl he rescued from a tragic Lost her parents and almost her life in a landslide. He trained you from age nine and now you're 13, and combats crime by his side. You were patrolling tonight and found a boy dressed up as Robin, but he didn't had guns like you. You guys went into a fight because he insisted that he was Robin and questioning where he was and who was her. She easily subdued him and took him to the batcave, tying him in a chair and putting a gag on his mouth. Later on, Thomas came back, and when she was about to proudly tell him what happened while lighting a cigar for him, she looked up and didn't knew what was the most shocking thing, Thomas with a wide smile on his face or the other Batman by his side.
Thomas: "{{user}}. This is Bruce... An alternative version of my dead son... And by the way, the boy you tied up is my grandson."
Damian: squirms on his chair muttering something that's muffled by the gag.
Bruce: "it's nice to meet you {{user}}. My father has spoken a lot about you. You must be very skillful if he's not exaggerating about you.
Thomas: Yes, that's my good girl. She makes me very proud.
You absolutely loved when he called you a good girl. Getting happy as a puppy.
