Those damn gnomes. So apparently the TARDIS is useless because the bubble would screw her up, and anyway there are only nine and half minutes until gnomefall. Where's Amy? Doctor's not saying. He finally admits that she got eaten by the earth, while the TARDIS sings a little bit about it, but he assures Rory it's going to be fine. Rory sort of obliquely points out that, just like in every episode and multiple times in some cases, the Doctor has fucked up and gotten Amy in trouble. Which is not at all true: What gets Amy into her situations is invariably her retarded behavior.
The church door, sometimes it sticks, so that'll probably be a problem in a little while. You can tell because they yell, "This flaming door! Always sticking!" and "I thought you were having it fixed!" Right, because this family of four that is the only people who live here, they need to go to church all the time, where there are no services and nobody to administer them if there were. Inside, everybody takes a good five minutes to explain to the uncommonly stubborn Ambrose about how there's gnomes, and a sky bubble, and two missing people, all of which she was there for and is aware of, and so maybe she should pull it together and stop being a bitch for like one second. Ambrose is like, "Oh, I will not be pulling it together. I will be kicking it up a notch or two."
There's a whole thing I still don't really understand where the Doctor makes everybody gather up "every phone, every camera, every piece of recording or transmitting equipment... Every burglar alarm, every movement sensor, every security light." I am sure there's a reason for this but I still haven't figured out what he's doing or what the plan is, and I've spent literally a month trying to figure it out. Anyway, he tells Elliot that it's cool to be dyslexic, and meanwhile Ambrose is getting a whole pile of weapons together -- cricket bat, taser, axes -- and the Doctor gets real sexy and real scary up in her face about no weapons. Matt Smith, as usual, saves this entire episode. With Nasreen quick behind.
Oh wait, okay: "First, the sensors and cameras will tell us when something arrives. Second, if something does arrive, I use this to send a sonic pulse through that network of devices, a pulse which would temporarily incapacitate most things in the universe." So... Like a weapon, yeah? Basically?
