Stacy has not moved an inch
Stacy was still squared up against Eric. She stopped screaming at Eric, but she did not look away from him for a moment. She was aware that all of these men in suits were approaching and she was waiting for them take action.
Eric did not want to wait.
Get out of there
He realized that he was wrong for whistling at this woman, but he was about to just willingly face the consequences of his actions. He quickly looked around him and saw an alleyway that none of the suited-up men were close to.
It was his opportunity!
