Interesting approach to the Jeremiah story, they found a way to sort of merge the canon events with the "Joker did it" history from Batman 89. I haven't noticed before if they've done it but Bruce's trenchcoat has leather sleeves evoking Batman's bracers. I'm assuming Barbara (who looks frickin' amazing in this episode) is going to meet a bad end by the end of the series forcing Gordon to raise the child (who he'll name Barbara in her honor) to set up the canon status quo.
