I think the "we" includes other young women that know who Lucas is. They may be at a restaurant, or at their place of work, and Lucas comes in. They may be down town and see Lucas. It's likely that he does film young women he sees for his "personal pleasure" when he gets back to his fart room. He's done it before when he went to the Globe.Dream chaser comes off as something of a nut herself. I still don't get what her issue is in all of this. Is she somebody he was creepy with on a dating site or did something weird at her work or something? It just seems like there is something personal going on and its getting rather obsessive on her part. That said its not all that hard to get a restraining order against someone doing insane shit outside of a business. Though I don't think most would bother unless he goes further with it or has a history involving someone working there. They'll just boot him from the property and if it doesn't work they'll pull a starbucks on him and have the cops talk to him and if that doesn't work then he has become a problem for the business and they can get a restraining order. All that aside, it can't be good for business to have someone like him standing out in front ranting and raving and recording people like that. I know if I owned a business he did that in front of I would be doing something about it real quick
Also somehow I suspect that 'we' refers to her and her fiance she keeps bringing up. Though that brings us back to the 'what is her stake in all of this' question
