"As long as there's been something in the corner of your eye, or creaking in your house, or breathing under your bed, or voices through a wall. They've been running your lives for a very long time, now, so keep this straight in your head: We are not fighting an alien invasion, we're leading a revolution. And today, the battle begins!"
...Don't got it. Canton asks why they didn't just tell him this, and of course they've told him this before but he doesn't remember it because that's how it works, and since the Doctor couldn't tell him all about the aliens and refresh his memory -- despite them spending three months playing grab-ass with him and constantly reminding him about it, and the daily visits to the Doctor in his perfect jail cell which Canton apparently thought was real, until suddenly he didn't and was all of a sudden in on the plot and had never shot and killed the people we just saw him shoot and kill. To distract from that mess, let's have a practical demonstration:
Canton fixes the Doctor's bowtie, because he is gay, and everybody stares at him. He looks down and his palm is blinking, because he's just left himself a message. Apparently there's a Silent in the TARDIS with them that he saw. Except just kidding, it's a hologram that they "extrapolated" from Amy's phone picture, and -- per the recording we're listening to -- the Doctor instructed Canton to look at it, I guess with everybody else turned around, and then once he'd broken eye contact, fix the Doctor's bowtie. So that's what he did, because mind control. So then we talk about mind control for a while, Rory goes, "Ruling the world with posthypnotic suggestion?" and then before that thought is completed, new topic.
"Now then, a little girl in a spacesuit." They got the suit from NASA, but where did they get the girl? Probably anywhere, but likely near the warehouse, taken from "somewhere that would cause the least amount of attention," so that's why Canton and Amy are going to the random orphanage.
Except, of course, that's the first time the Thing has happened this year that kept happening last year, where what we saw was not at all what actually happened, meaning that we jump-cut from inside Canton's perspective, which means that's going to be happening this year, which means that nothing we see might actually matter or be happening at all, so we'll have to wait until Fall 2011 to find out what we're even watching, because there could be literally entire episodes happening between shots every time they cut camera or switch to a new setup.
