It's a little difficult to know everything when you don't know how to monitor the city for fluctuations and breaks in the normal flow of time. Not his fault, and it's certainly not Terry's. While it's true that he sometimes (see: often) goes looking for trouble, this was just something he stumbled into — or fell through, is more like it.

Had he not tripped, fell, and stumbled into the past in the middle of this classic bout of criminal activity, he would've had time to yank the batsuit out of his bag and find somewhere to haul it on. But there hadn't been time for that, and Terry had learned a while ago that it wasn't the suit that made him Batman. It was what he brought to the table. Batman was Batman, with or without the suit.

And speaking of...

"You have got to be kidding me."

Terry pushes himself up, bracing himself against the wall to avoid slipping on the floor again. Someone really ought to put up one of those wet floor signs.

"That's the look you're going for? Really? Am I ever glad you lost touch with your armored warrior side."
