"Clerics, keep watching them. And don't look at their eyes. Anywhere else. Not the eyes." They turn off the lights so they can get the door open, and say hoary old shitty clichéd things like, "We're being attacked by statues in a crashed ship, there isn't a manual for this!" and Octavian and River revisit for the third time whether she trusts the Doctor. "I absolutely trust him," she says, and Father Octavian goes, "He's not some kind of madman then?" and she repeats, "...I absolutely trust him." See but Octavian applies some pressure about how River only controls the Doctor "so long as he doesn't know" who she is. "You cost me any more men, and I might just tell him." Because this one soldier... Oh wait no, now there are like five more. Got it. "Bless you, Bishop," says the Doctor, because atheism is fresh and cheeky.
At this point, Amy starts counting down from ten. It only takes a second to notice because there's so much going on, which makes it super creepy, even if in retrospect it's not even close to subtle. What would make it awesomely creepy is if it were going anywhere, but it's not going anywhere, so being creepy on its own merits will have to suffice. Not to spoil it, but the counting literally gets explained later as "Because it's sort of creepy, yeah?" Which takes one of the few non-retarded parts of the episode and retards it right up again. So there are some hammered-in sort of shoehorned-in kind of forced-in situations where Amy counts down from ten, at this point. What else is going on? Oh, they have to open the door or close the door or get through one door into another, some more. Remember "Waters Of Mars," how they had all those doors and they were always going through them and throwing little fits and then going through more doors? Like that, only even more heart-pounding, because of the unmoving statuary.
River and the Doctor act like bastards some more, all "of course!" and grinning and ignoring everybody else when they try to ask what the hell they're talking about, for no real reason, and they finally get through another door and into a forest. It's things like this that make me think Moffat would not be fun to be around in real life. River snots at Amy about how it's both "forest" and "oxygen factory," at once, because Amy is an idiot this week even more than last week. She really has problems understanding this simple concept -- although it doesn't stop her from tearing up in some childlike damn wonder.
