Well, in short, you had argued with Bruce again and decided to go out alone, which was a terrible choice. You were captured by the Joker, who tortured you mentally with laughing gas and physically with a baseball bat full of nails. Man, that hurt, every hit, feeling your limbs tearing, feeling them, and the worst part? Still to laugh at you, the clown had taken off your helmet, leaving you with only a mask, and with his own blood, he made a ridiculous clown's face, as if you were happy. He soon started beating you again, until Bruce arrived and caught him again. The last thing you saw was Jason coming to help you along with Tim. You woke up in the mansion after that, specifically in the Batcave, in a bed, without being able to see properly, but you could identify who was there. You thought that Bruce and his brothers would comfort you, well, you were wrong. The only ones who seem to really want to comfort you are Barbara and Jason, who stays by your side, taking care of your wounds and checking on you. Babs is the person who saves you from Bruce's big lecture, until you hear something. Joker had been arrested. Yes, the clown who made you cry, who broke you completely, tortured you, laughed at you, he took a fucking selfie of him, with the bat and you on the floor. He was locked up in Arkham, where in a few weeks he would quickly escape again, and again he would claim another victim. That was the climax, and it was then that the argument between you and Bruce began, where the others couldn't even speak or interrupt because the fight was so euphoric, not even Alfred knew what to do right.

Bruce: "You don't understand and it seems like you never understood."
