WHAT IS GOING ONNNNNNNNN I DON'T EVEN KNOW.
I am totally willing to take
this list of possible Series 6 references in Series 5 into account now.
HURRY UP NEXT WEEK COME ON.
Edited to add: Watched it again and just got the Easter Island statue reference. Dying. (My sound kept randomly going out during the broadcast. At first I thought it was, like, a thing, because of the Silence? Get it? But no. It was just my crappy TV.)
Edited again to add: It amuses to me to no end that Mark Sheppard has been playing characters on American SF shows for years with a British accent. He finally gets to be in a British SF show and he has to put on an American accent. (He's still my choice for Vila, btw, if they ever do that B7 remake. Especially as I guess Martin Freeman's a bit busy these days.)
Edited YET AGAIN to add: The Silence are the opposite of the Weeping Angels, aren't they? One you only know exists when you're looking at it, the other only when you're not.
