Harley Quinn "Relationship"
I hope the Harley Quinn romance actually leads somewhere like her potentially ditching Joker for Bruce. In this Batman universe it seems like Harley & Joker have basically flipped roles and now she is the manipulator. I'm not sure if I buy the whole "serious talk" we had in her office, its really hard to tell whether she was actually serious or not about apologising its like she has two personas right now. Anyway I tried rejecting her in my second save file and her angry outburst really demonstrates that she would rather have you over Joker.
Hope we can pursue this further while continuing to make Joker jealous, it would be hilarious if this relationship is what pushes John Doe into taking the persona of the Joker but yeah anything can happen I guess?
