A quick addendum: Fortunately, the aforementioned YouTuber refrained from going too deep into specifics. But as it's already out there now, I'm thinking that the scene in question takes place during Batman's heated brawl w/ the GCPD (the same one that's been shown in early promo images and trailers). Assuming she didn't misspeak, and some random cop does, in fact, manage to unmask the Bat, it'll be very interesting to see how he recovers from that. I'm guessing that he'll simply pull out something from his utility belt and use it to obfuscate his identity or scamper off into the night before anyone gets a good look. We shall see.
