Amy finally drops on the ground and has a big dramatic lie down. Octavian is not interested in dealing with that. River yells, out of nowhere. "Father Octavian, when the Doctor is in the room, your only mission is to keep him alive long enough to get everyone else home. And trust me. It's not easy. If he's dead back there, I'll never forgive myself. And if he's alive, I'll never forgive him." But it's hilarious, because the Doctor is standing right behind her. How embarrassing for River Song!
The Doctor tells Amy that the crack in the wall is the end of the universe, and then yells at her and frankly is a real jerk for no reason. I'm not interested in this part at all, where the Doctor yells at people to shut the fuck up while asking them questions because he's thinking so hard. I think that's going too far, it's neither funny nor meaningful because it's so shitty. Maybe if you have no social skills that wouldn't seem like a really terrible thing to do, but it is. Just take it on faith. On the other hand, it provides a texture that rubs up against the only actually important scene in this episode, coming up in two paragraphs, that makes it really quite effective, so it gets a pass.
Amy rolls around on the floor with Angels in her eyes, something we've known about for awhile now, and they explain it to us literally one thousand times, and Amy's pretty sure she's dying, and why's she counting? Because it's creepy. This is where Angel Bob explains that the counting is meaningless, except as manipulation. Of Amy or of us, you be the judge.
Suddenly Amy can't open her eyes or she'll die, because she'll keep counting. That sort of makes sense. The Doctor leaves Octavian and the Clerics to look after blind Amy, and takes River off toward the Primary Flight Deck, where they will stabilize the wreckage, stop the Angels, and cure Amy. How? He'll do a Thing. What Thing? "It's a Thing in progress, respect the Thing. Moving out!" Am I wrong or is the third time he's made that joke? Octavian doesn't want to let River out of his sight, but doesn't explain yet that he is her chaperone and that she's officially still in jail. Why? So it will be more mysterious.
"I'll be back for you soon as I can," the Doctor promises, and blind Amy says, "You always say that." They say goodbye and take off, and Amy worries to herself, but then suddenly the Doctor appears, wearing his jacket, more worried and compassionate than he was a moment ago. He begs her to trust him, at length. "If I always told you the truth, I wouldn't need you to trust me... Remember what I told you when you were seven?" She doesn't. He begs her to remember, holding her temple against his own, nearly weeping, and then kisses her forehead and disappears.
