It's right after they have stolen the mask and Macdougall said the stuff about, "Now its time to play, truth or dare!" After he pushes Gin's head down for the last time, watch her hair. She begins to tell him about the money and what he gets out of it. Watch her face. Her hair is completely in her face, but when the camera gets a shot of Mac, and then back to her again, it is wiped away. It happens again, but the next time, the hair is back in her face.
