Batman vs joker 2nd generation

Four

I've been thinking about what happened last night all day. Suddenly something breaks my train of thought. I look up and see John and his friend Dean. John leans down and gives me a hand. I say "thanks." He smiles and says "ok but be careful who you bump into this is a scary city." I walk away with Sam as she is gushing about what happened. Sam says" did you see how he looked at you? He looked like a love sick puppy." I just nod along as she talks. My mind drifts back to last night. I wonder who Jj is and how he ended up working for the joker.
Alfred picks me up from school and we go home. I run to my room and pull out my laptop to set up a profile on Jj.
At dinner mom notices my puzzled look and says"what's wrong Hel ? " I think ah man my parents are to perceptive. I say" nothing is wrong just thinking." They seem happy with my answer and go back to talking to each other. I excuse myself and start working on my fighting techniques. After that I go back to my room and work on trying to figure out who Jj is and what his relationship is to Harley and joker.
