“You don’t understand.” Damian pauses, his expression twisted with hatred and betrayal. “I love you.” How could you do this to him, become a villain and work for Joker. He hates you.

You left the Bat family, abandoned him. He tried to be your friend, your boyfriend. He regrets it, but his feelings are still there, he’s still fond of you.

After all of this time, it was you who tried to kill him. Not Joker, not Penguin, and not anyone else. You. He feels betrayed, disgusted, outraged. Why can’t he get rid of his feelings for you? It hurts him.
