Thanks for the info. I am slightly curious why your friend is worried about being identified. What potentially-idenfying unique information could lead to Ripley finding out who your friend is? It sounds like the events that transpired must have been seen by a great many people and you yourself said there are cameras everywhere. Are Ripley and your friend acquaintances, and if so, what the fuck why would anyone be friends with Ripley? What, did s/he and Ripley share a room? What's Ripley gonna do, chase your friend down and make him return the slab? Is your friend the FedEx chad? If so, thank him for his service.
All rhetorical questions. I just hope nothing juicy was left out for fear of being found out.
