Wait a minute...maybe we have this all wrong.

@cortexiphansession: I think that the looks he was giving Walter could also be shock and shame that Walter saw him kill someone - even a shape shifter. Anger and shame that he was caught, but still got on with the job.

@Ghost in the Machine: I wasn't surprised because when they said the blood type and Walter said it was his, I thought 'it is probably his son's type as well.'

@Sheryl Nantus: Yes!

@Annalee Newitz: That's funny that I saw and S in the top cube! I was picturing a blocky shape instead of the curvy.

@Felipe058: Top cube is S, third one down is E and bottom cube is X. It is supposed to be 'subliminal' so it is subtle.

@Zalethon: "Mark Zuckerberg says that our idea of privacy as a social norm has evolved."

@Zalethon: Yes, he is totally correct.

@lankist: That reminds me of the contests where they say, "Create a new logo" or "Name our new product" and win a crappy prize.

@saladinahmed: " How about just having a good 19th c. historical crime series?"

They better not set it too late in the '40s as he died in '49.

@FrankN.Stein: Me too - it would be first on the list for me!

@afrocoolbeans: My daughter was born in 1995 the year that the movie came out and it was her first full length movie that we bought on VHS. She watched it so many times that the case was literally falling apart.

@TheGreat&PowerfulTurtle: Agreed.

@TheGreat&PowerfulTurtle: Went to his website - Yikes!

Earthworm Jim! (sorry the pic is so big)

Reminds me of the Doctor Who episode with them living forever in cars "Gridlock" the horrible smog.

The firefly story also seemed like a reference to Bradbury's Sound of Thunder with such a small change having such significant consequences.

@Lawdog: It was the ingredients for the milkshake - the sweet whey - which might be considered uncommon.

@Lawdog: Better call an ambulance because after tonight's episode and all of the Observers, famous guest stars and food references, it is alcohol poisoning time!
