"City called Gotham," he answers, for the fact that he can answer it at all. "I'm Rob," he adds-- a half-truth, maybe a fourth of a truth, but the fewer people connecting Gotham and Tim Drake in a strange place, the better. The last thing he wants to be is some rich-kid hostage in another dimension.

Though, if it would get him back to his own world, maybe it wouldn't be the worst card to play. At least Bruce would know where he is, and that he could use a hand getting out. "I'd say wrong place and wrong time, but there's no rhyme or reason with people who show up here, far as anyone can tell."
