Wow.
1) Bethany, as many of you have so rightly believed, is not dead. It was a faux death all conjured up in the mind of Bob, with allusions made to the scene in American Psycho where Patrick Bateman decapitates Paul Allen to the tune of "It's Hip to be Square" by Huey Lewis and the News. That was the music playing in the background. I mean, come on, he even quoted directly from the movie ("Try getting a reservation at Dorsia now you fucking stupid bastard!"). Russ and George just duped most of you into believing that she did, for the sake of this major publicity rouse to which I am currently contributing. So let's get this clear: Beth did not die (she didn't get enough votes as said before by other posters).
2) Roger, on the other hand, is most certainly dead. We are foreshadowed to the indelibility and credibility of this death by the appearance of the words Ex Machina from the phrase "Deus Ex Machina", translated from Latin to mean "God out of the Machine". Someone has said this before but it is a plot device that appears spontaneously (suicide) to correct a situation in the story (Roger being alive)
3) "Goodbye, Farewell and Amen" is the final episode of M.A.S.H. where Hawkeye Pierce reveals that he, like Bob, silences a compatriot within a vehicle. Just a cultural reference here.
4) The author of the book on law, A.Macris, is one of the executive producers.
5) The Suicide Kit of David Carradine (as first featured in Knives-R-Us) was what Roger used to off himself. Any relation to the actual Carradine's death?
6) Noticed a stand in the background near the beginning before the roadkill. Any explanations?
7) Some voices in the background. Sorry but I can't really get this one; can anybody?
Overall, lovely episode. Shame about the background voices though; hopefully someone can help me on this one.
