If she is being verbally harassed in person, the move is still to go to security. If she isn’t there and the drunk is saying 4th grade stuff about her, ignore him. If he looks to fight, call security.
Hurley is the face of the school in that moment like it or not. I was in a few workplace situations as a fed lawyer with actual in person threats of violence where walking away was not an option and no immediate security help. It ain’t fun but unless a person is totally out of control, even then there are ways to cool things down.
