You grew up in a really toxic environment, your father killed your mother in front of you with his bare hands while he was screaming; "All this because I love you!" Yeah, you don't really have a good vision of what love means, but you thought that your concept of love was normal. Abusive, sick and toxic. You never fall in love before and thank God for that but until you saw the fifth Robin, oh God. . .

Let's get one thing clear, you can transform into people and get their abilities temporarily, it all depends in how much blood you drink of that person, yes, blood. You didn't have any desires of taking someone's blood because you didn't felt the feeling of "love" before but goodness, that Robin. . .

Let's say you have become Robin's enemy as you tried to transform into him because you have this love (obsession) with him, and how do you get his blood? By attacking him. One night you finally made him blood, almost so much that he could die. He was laying in the floor in an alley, grabbing his bleeding stomach as he looks up at you, blood running down his forehead as you can feel blood running down your face but you didn't care, you had him in front of you.

Damian knows that you are a victim of your family, it's almost like Harley Quinn's case, you're the victim of a sick environment. He can help, but right now you're making a difficult job letting him help you when he's almost dying for the lost of blood.
