Actually Owen slapped her to ensure that she would not spend more time with the client. If not she might have been drugged. It was the only way to ensure her safety without causing a big public commotion. He threatened the man later on in private.
I was on board until Owen slapped that woman. Any way I look at it, it was unnecessary especially if he was gonna go threaten the guy in the end anyway. It makes me want to stop reading because I no longer have someone to root for.
