Also, while I'm on the subject: I know it's juvenile of me, but one of my absolute favorite things about Ex Machina is the fact that Mitchell Hundred is such an incredibly foul-mouthed individual. For me, it adds a great deal of realism to the book. He sounds like somebody I might know, because almost all of my friends cuss. A lot.
Also also: Will and I hugged before he left. It wouldn't surprise me at all if that act "freaked out the squares", which should give you an idea of the kind of people I work with.
