Bathroom scene question
The scene in which Warwick is having sex in thin air while John is in the bathtub really confused me. First of all, I wonder why we didn't get to see the "person" he's having sex with since we've constantly seen his "mind-people" during the party. And it makes me wonder if he had sex at all (in his mind, i mean). Because he had his underwear on. I seriously thought he was going to rape John. I'm probably not making myself clear here, but if anyone has any input... what is happening in this scene? And why is he having sex (if he is) in front of John?
I really liked the dinner party part of the movie so I'd like to understand exactly what's going on.
