The more I think about this episode, the more I think it's pretending to answer a lot of question but not really.
For  example, how on bloody earth did they get from the Warehouse situation  to Canton pretending to hunt them down? Or from the Doctor telling  Canton to look behind him at the Silence (what a rubbishy name) to  having the Doctor all chained up?

With a rubbishy beard 
and a self satisfied little smirk, completely cool and collected and charismatic in the face of 
anything.
And  where exactly did they get the materials to build the knock-off  Pandorica? And when exactly did the Doctor and Canton have time to cook  up this plan? And how did they get the TARDIS into Area 51? And where is  Future!Eleven's TARDIS?
Shit has happened in that warehouse and now we're going to have to wait to figure out what, exactly, happened.
Bollucks.
Just amp up the anticipation and the suspense why don't you.
Though, I have to admit, when "three months later" scrolled down at the bottom and it showed Amy running

the first thing that popped into my head THANK THE TARDIS THERE IS NO BABY BUMP.
And I was very happy. And then Amy was like oh I was mistaken and I was even happier.
Even  though I think the Silence is a bollucksy name for them, I do admit  that they work fantastically as television monsters. I mean, I don't  think their effect would be quite the same in like a novel.
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.
Oooo. Shivers.
But this scene here, with Amy, in the orphanage? Chills when I watched it. 
Chills.

First, everything is fine. Creepy, but fine.

Hands! Oh my god! And then the very next frame:

!!!!!
WHAT HAPPENED TO YOUR FACE
And of course, the weather doesn't help a bit: it was a dark and stormy night. Oooooo.
Though, this entire orphanage scene also raises more questions than it actually answers.
A).  Where did Amy actually get the pen? In the beginning, the episode  always showed a pen dangling from their necks. But there is no pen  anywhere on Amy's person that I noticed -- just a flashlight. So, who  marked her up -- or was it just a continuity error?
B). If the  pen-less-ness was just a continuity error, then why would Amy mark up  her face? That just seems like it would be awkward and unnatural because  it would be even harder to see the tally marks (no peripheral). But  then Rory was all marked up on his face too, so maybe I'm just  overanalyzing it. The marked up faces are more compelling than arms and  hands -- but I'd still like a reason. /pout.
C). And what  happened in the lost time? Something significant or Amy just counting  how many of the creepy Silence are haunting the "orphanage" (if it's  even still a real orphanage, herrrumph)?
And who is this woman?

Who's  dreaming and what's the dream -- though, to be honest, I'm hoping it's  not something similar to what happened in the Library episodes.
Still. I'm going to guess there's a perception filter at work here. I bet that bedroom wasn't even real.
I hope not because there's this:

It's  like -- ah, can't get away from the pregnancy! But, the closing scenes,  the one where it showed the bio scan oscillating from negative to  positive gives me hope that a) there won't be a pregnancy period or b)  even if there is a pregnancy, there'll be a rousing good story behind it  which will hopefully be ultra light on the soap opera aspects so many  of these arcs tend to take. (And apparently, the tumblr-verse is calling  it Schrodinger's Uterus, which kinda made me smile, I admit it.)

I adore the framing of this scene, just fyi.
I love Rory. What a beautiful man.
Rory:  She can always hear me, Doctor. Always. Wherever she is, and she always  knows that I am coming for her, do you understand me. Always.
Amy: Doctor, are you there, can you hear me? Doctor -- oh god. Please, please just get me out of this.
Rory: He's coming, I'll bring him I swear.
I  love how the show still highlights Rory's insecurities, but how it  never dwindles into some machismo bullshit. How, even when he's not sure  whom Amy loves in that one scene, it seems like his love for her  transcends the territorial, melodramatic relationship patterns that is  so stereotypical of so many shows these days.
And that's so, so beautiful. (Though, now that it's established that Amy loves Rory, I hope the show won't keep on pointing it out to the viewers, no matter how sweet it is.)
And I love this weird, little, simple, beautiful relationship that is beginning to form between the Doctor and Rory.
Especially when they talked about Rory as a roman in more than an off-the-cuff sort of joke:
Rory: Rome fell.
Doctor: I know, I was there.
Rory: So was I.
Doctor: Do you ever remember it? 2000 years, waiting for Amy - the last centurion?
Rory: No.
Doctor: You're lying.
Rory: Of course I am.
Doctor: Of course you are. Not the sort of thing one forgets.
Rory: But I don't remember it all the time.
And  in this moment, Rory becomes more than the boy who waited for Amy all  those years, but he becomes someone more -- it's acknowledged  (understatedly, which are the best kind of statements), that Rory is,  technically, 
older than the Doctor. That he is, in some ways,  equal to the Doctor -- and yet, in many ways, not because he doesn't  remember it all the time, unlike the Doctor. But, I thought this would  be an interesting aspect to have in the companions (because Amy isn't  typical either, what with the whole of time pouring through her head  growing up) and I wasn't sure if it'd be ignored or what -- but, here it  is. And it's so lovely.
And it's part of what makes this  relationship between Eleven and Rory so endearing that I can't even  describe it -- it just, made my heart melt whenever I saw him interact  with Rory, how he sort of looked at them out of the corner of his eye  when they were kissing their I-love-yous. It was just.
That's true love, there. In all its forms.

River: My old fella didn't see that did he? He gets ever so cross.
Rory: So, what kind of doctor are you?
River: Archeology. Love a tomb.
Oh, River Song. You are cooler than the sum of Indiana Jones and Lara Croft put together.
Also? Why don't Americans use the word "cross" more often? What a lovable word.
And the Doctor's description of her:
This  is my friend River. Nice hair. Clever. Has her own gun. And unlike me  she doesn't mind shooting people. I shouldn't like that, kinda do a bit.
Aw. Excuse me, I'm going to go melt into a puddle of goo at their little relationship/flirty/type-thing they've got going on.
I  suppose it'd be a rubbishy sort of review/musing/squee-fest if I didn't  talk about the girl, the nameless girl, the Time-Lord-Girl:

Couple thoughts:
1).  The girl is the "honour" that the Silence spoke of to Amy, maybe? ("We  do you honour. You will bring the Silence. But your part will soon be  over.") Except a pregnancy isn't exactly "soon," unless they were  planning to go all 
Fringe-y on her.
2). The girl is out of  time -- because of the photo Amy found. So, how did she get into the  time she is now? With the knock-off TARDIS? But why would the Silence  need a space suit if they had the technology to make a knock-off TARDIS?
3).  Speaking of the life-supported Space Suit, perhaps the girl needs it to  live -- which is why she is dying six months later. But why would it  take her six months to die if she needed the suit to live? And if she  needed the suit to live, why would she just regenerate? Unless the  process would fix why she was dying or why she needed the suit in the  first place? If something happened in the six months, then what and why  weren't the readers privy to it. *grumble (but only the good kind of  grumble)* I also noticed that with the three months later notation at  the beginning of the episode + the six months later at the end = nine  months, which is always a significant number because of the whole  birthing metaphor-imagery-thing at work. Balls.
Doctor: Incredibly strong and running away -- I like her.
(aside,  I do like that the show isn't always gung-ho about its heroes having to  be strong and bold and facing whatever's coming with squared shoulders  and what-not; it doesn't mind celebrating the Trickster nature of the  hero, and that I love.)
Misc. ThoughtsI love how  the show establishes how Nixon became so paranoid (record everything!)  which basically is a fan-fictiony explanation for Watergate:
Doctor: Oh, Dickie. Tricky Dickie. They’re never going to forget you.
Oh, excuse me while I giggle.
Also, I wasn't really expecting this:
President: This person you want to marry. Black?
Canton: Yes.
President: I know what people think of me, but perhaps I'm a little more liberal --
Canton: He is.
And,  despite the Doctor's wishes, it still hasn't happened yet! Hello,  Social Commentary. And they science fiction isn't relevant. ;)
Also: Eleven and River kissing. I love how he doesn't know what to do. It's so adorkable. I just melted inside.
