"From our Gotham? Four, including you. Myself, I'm from that night that Butch revealed his true colours. Victor Zsasz, he says he's from some time on, maybe a year? After Sofia Falcone returned to Gotham." He glances at Oswald for recognition of who she is. "And Pennyworth, who is from some time later, but I've never found out much more. Usually there's more pressing matters, like his impending arrest."

He hums for a moment. "There's at least four others from a Gotham, but they all seem to be from several decades ahead of us and a different history than our own timeline. None of them have known the name Galavan, or that you were Mayor. That's Tim Drake-Wayne, Jason Todd from the Narrows, Dick Grayson, of the Flying Graysons, apparently, that clown and acrobat who got engaged in the police station are his parents and Roman Sionis, who is Richard Sionis' son who was obviously not ever conceived in our Gotham." He ticks them all off his fingers.

"Now, them aside, I've met several people who know of Gotham, which a lot of these people and their worlds don't seem to, but they're further ahead than us, again, and seem to be closer to contemporaries with Tim and the others." He nods firmly. "I think that's most of them. I know I've just given you a lot of information. The most relevant are Victor and Pennyworth."
