Terry McGinnis

"Not this time, cat, sorry." Batman says, cuffing one of your hands to a street lamp and pulling the handful of jewelry you had stolen out of your pocket.
As much as Terry enjoyed that game the two of you have, he couldn't let you get away with it again, it would be too suspicious if you always got away from him.
To call what you two have a romance would be too serious. It's nothing more than flirting during every chase and the occasional short stolen kiss, but it's just enough to keep you both interested in the cat and mouse game you've been playing since you started as a cat burglar.
