i think that whats gonna happen with "mr j" is that he stays dead and harley has a baby, hinted cuz she sings lulibay at end, and scarecrow come out of hiding to be the father figure ( he really haz selfish motives, pherhaps testing gas on baby?) or i guess riddler could be father figure (using baby to answer his version of what walks on 4 legs in morning, 2 in afternoon and 3 at night (  his answer is baby, cut off arms, let it walk then give it a walking stik) ), or they could both help raise (and terrify) the baby.

oooh and theres that story where harley beats and tortures robin and turns him into "joker jr"

that could happen if scarecrow and or riddller kill baby with experiments and riddles, then thered be gang war between riddler\scarecrow team up and harley\poison ivy\catwoman\ any other (mostly female) villains who feel bad for harley, of course all jokers rivals would team up with r and s (riddler and scarecrow) to try and finnish off whats left of harley and jj ( joker jr)

then turn on each other like wild dogs who have run out of food
