Nora entered the elevator with her four security details hot on her tail. Other people who didn't know who she was looked at her with curiosity wondering who she was. Only royalties and important people were seen walking around the city with security details following them around so they assumed that she was one of them.
Other people who knew her knew to steer clear of her way. Nora Parker's family is a known philanthropist and while people from the lower and middle classes looked at them with respect and high reverence, the people in the higher class were cautious of them. Especially Nora who is now rumored to be the next leader of the Robin Hood Society.
If you were someone who was part of the elite circle but with a questionable background, you wouldn't want to catch the Robin Hood Society's attention. But if you were someone who has a clear conscience, you do not have anything to worry about.
