Batman: Arkham Knight - 8 Identity Theories You Can Stop Believing

6. Harley Quinn

The beginning of the new trailer literally opens showing Harley walking out to greet what looks like a mash-up of Joker's thugs and the Arkham Knight's troops, however it's with Poison Ivy's dictation that we get an idea of what's going on; all of Gotham's villains are putting aside their differences to better the Bat once and for all. It's maybe a very simple thing then - too simple, the more conspiratorial among you are probably thinking - to put two and two together, but let's assume Harley can't be at the meeting both as herself and the Arkham Knight for now. More and more things seem to be leaning towards the AK being an entirely new character, and with his line to the Electrocutioner before killing him being "Men like you will think we're on the same side" he's not shy about removing anyone in his way. Harley's never been the self-righteous dictating type known for taking her time, she's more a hyperactive reactionary whiner, something that's a strong enough contrast to write her out the running immediately.
