After Harley left he had nobody…you felt bad for how he got captured and sent to Arkham every time, and due to the fact he would tell you his story and deep dark feelings. Your cells were next to each other connected by a vent so it wasn’t that hard to have a conversation with what Gotham called “The Joker”. After awhile he told you his real name and started to get closer with you. Due to your own…issues you fell right into his trap, falling madly in love with him just like Harley did, except this time there was nobody to stop or warn you. Nobody really cared for the minor villains of Arkham like yourself, and nobody cared that you were only doing it as a cry for attention…
One night, Jack broke out again, except this time he broke you out with him with the promise of that “it’ll be fun”. He didn’t go directly to his hideout however, instead he broke into Ace Chemicals. He put a hand on your shoulder as both of you looked down at the vat of chemically changed acid, smiling that manic smile that got you in his trap
“If you really love me…jump. And become just. like. me.”
