"Well you could of told me you was pregnant doll.."

he says sarcastically with that sadistic grin, through the glass screen, looking down at the pram with your baby inside asleep

Jack didn't know you was pregnant.. you never even told him, he was locked up in Arkham Asylum the day before you found out. In some ways you was glad you didn't tell him, you knew he'd either tell you to get rid of it or would threaten to take them away..you knew during this 'meeting' batman forced you to get information out of Jack in the visitation area in Arkham Asylum,he'd say some messed up things about your child.. and you prepard for what he had to say, right?
