Batman vs joker 2nd generation

Eleven

On our way to the crime dad says" Hel I'm sorry I didn't tell you but I wanted everything to work out first. I want to tell you we are getting a new robin. It is Barbara and Dick Grayson's kid. His name is Jason." I am about to say something but then we get to the place. And we see Jj in the middle of a fire with a police man his wife and  their two children. Jj yells" give me joker and Harley  or they get burned alive. Oh and to make things interesting I'll send the kids out but only if you send in batgirl to take their place." I turn to dad and say "I have to the kids are scared and I am trained if all goes wrong I have ice pellets in my belt. I accept." I turn towards Jj and leap in then get the kids out.
      Jj looks at me and says"quite brave for a girl." I ignore him and check on the cop and his wife. They have mild burns. I give them burn ointment and then turn to Jj. I ask " why are joker and harley Quinn so important to  you?" He just turns away. He keeps checking his watch and is anxious. The flames rise higher around us but then I notice. He has a mini sprinkler system that douses the water when it gets to close to any of the hostages. Is mile and think he does have a part of him that doesn't want this.
      I turn to him and say"does the joker have your parents or someone close to you because I know you don't want to do this otherwise you wouldn't have sprinklers and be so anxious.We can help you but only if you want to be helped." He turns to me and says" they don't have anyone I love. But their the closest thing to family I got." Suddenly it all clicks. I gasp then say" they are your birth parents. That's why you work for them." He just nods and stares off into the distance.then shouts" batman you've got an hour until I start killing hostages."
