Police
After nothing happened for a few moments, the security guard called the police to remove Jess from the train. While the police were on their way, people were still trying to convince her that she didn’t have to do this and could just move her bag. At this point though, she seemed to have already made up her mind.
Even though you could see that Jess knew that the police were coming to take her off, she acted like she didn’t care. We think that her inflated ego was massively damaged during all of this, along with her self-pride and entitlement. It would take a lot for her to now admit defeat.
