Chris and Rob have somewhat plausible reason for being there, for Chris it's checking up on Anna and David in disguise of stealing panties, for Rob it's being a friendly neighbour could be for invitation for a dinner at Rob's for Anna and David or for the reason you've said.
Jake have minimal reasons for him to be there in the morning if Anna wasn't drugged the previous night, if she was I can understand him being there but unlikely as he already made sure she was alright the previous night. Chip and Dale makes absolutely no sense, can you imagine the convo "oh we liked squeezing your ass in the office, so here we are at standing at your door step 7 in the morning". That's borderline Kendra level of insane.
Club guys and the photographer were paid for a job, they already completed their job.
Lmao. I doubt anyone thought they were anyone of them.
I would be angry if it's a new character, what a waste of time that will be. It can be Anna's bro explaining the situation and asking money asap or too much money, that will put pressure on Anna to accept whatever terms Grant puts. It still will be a waste of a preview tho.
She's a women, unless I'm wrong and what?
Certainly unless it's Chris.
