#jay!robin

After dying and coming back to life it was Joker that found him robin(or he revived him himself) and recognized the scars he had as the ones he gave. Then to prevent Harley from leaving decided to make him into Joker Junior (he already had the plan to do it to the new bird but why not use old material to make a new joke plus he was already a clean slate!). He tried just talking to him at first thinking that it was like amnesia and maybe he wouldn't remember and would just learn to talk and such like a baby new to the world. When that didn't work he decided to use shock therapy to get his brain working and it did work. Slowly the kid started to remember and have new thoughts put into his brain that he was Joker Junior or JJ. His past memories were weird and mostly different and only really remembered in dreams or when told by Joker(false memories there). Batman didn't know that Jason was alive and Joker didn't advertise him at first until he new he had him under his control so Batman didn't know to come save him. Eventually Batman does find out and that's where I leave off
