So, S1 cliffhanger: I'm guessing it's going to be a zoom out from Juliette as she walks away, as Bernard says that line from the book, "Silo one, this is silo eighteen. We've got a problem."

Or is it going to show her entering Silo 17, and seeing that the airlock is jammed open, the silo is dark, and everyone is dead?

They're obviously playing up the whole, "the view screen is a lie" thing, so a huge part of the cliffhanger is gonna have to be the revelation that, no, the view screen is showing the truth (presumably by, as in the book, the skybox in the helmet view failing as she crests the hill. Seeing the ruins of Atlanta off in the distance would be quite dramatic). The human race is, indeed, almost extinct. The last sheriff and his wife did indeed die on that hill after cleaning the camera. There is indeed something very nasty out there. They're all dead, Dave.
