Shit he's been found out- wait. This isn't the guy he stole from. He can't quite help the flicker of a frown crossing his face. If she wasn't that guy, did he actually steal somebody else's target? Part of him is thinking, 'if you snooze, you lose,' but technically speaking he doesn't need either items he stole.

"What? Gonna knock me out in an alleyway?" He can't help being difficult either. But he's pretty certain he can get out of this, even if it does go sour. So he starts moving away from the crowd.

Once they're a far enough distance away, he speaks in hushed tones. There might be less people, but that means the people who are there are quite capable of listening in. "Did I steal your mark?" He seems at least a little concerned.
