Clocktower: Donna/Cassie
[Over the years, Donna spent a lot of time in Gotham. Or mostly going in and out of it, since Bruce didn't like sharing his city. With anyone. She didn't know it like the back of her hand, but she knew their Gotham enough to recognize this wasn't entirely correct. It was different. The clocktower at least was very difficult to miss, because otherwise she might end up in the wrong spot.
Donna was already in her suit as Troia and she landed on top of the clocktower, looking down over the city. She'd gotten a quick update from the others, but seeing Cassie was a priority.]
