Cant agree on the the timing. Again, I guess.
There was a teeny bit too much fluff topad it to two episodes, but I wouldnt have cut a lot.
This one was edgy and kept me happy all the way through.
Not sure how many sonics were floating about though: Im sure it showed up in the wrong pocket at one point.
I didnt see ganger Amy coming, although at one point I was expecting a ganger Rory.

Well, I thought it was tense and riveting. I was horribly uncomfortable (in a fun way, I guess) at how Ganger doctor (or was he) was treating Amy in that one scene. And the twist that they switched shoes, very clever.

And that twist makes sense after the twist at the end! OMG! I think everyone and their dog figured that Amy is pregnant. But I don't think a person on the planet figured that Amy was a Ganger!

So, at what point do people thing she was kidnapped? She first say the eyepatch woman in episode 2, right? But she told the doctor that she thought she was pregnant in episode 1. So, in that three months between, perhaps that's when she was taken. Then again, the Silence instructing her to tell the doctor something . . . maybe she was kidnapped before the very start of the season.

One question though, why ? Why did the Doctor "kill" the Amy gangers. He could have kept her. I think that kind of breaks the moral of the episode

So they really had a bit of Jon Pertwee as well what with reversing the polarity.

Oh and Hartnell as well

According to Dr Who Confidential, Beth Willis says near the start that Amy has been a Ganger throughout the whole series, so before the Silence.

The Doctor said that the TARDIS had stabilised all of the gangers into being 'real' humans.
Obviously didn't work on Amy then.

I think that the Ganger Amy was being "run" by Amy herself - not independent as the other Gangers at the factory had become. The Doctor needed to separate that link between Ganger Amy and the real Amy, probably to save her during birth. Clearly, Ganger Amy was sensing some physical distress, but wouldn't handle the process of a proper birth since Ganger Amy wasn't pregnant.

I thought it was pretty startling to watch Rory's response to the Doctor's command to step aside. Pretty strong showing of trust.

I agree with MrGrumpy. There's was enough for 2 episodes. I like that the pace was able to really settle down for a bit before jumping back to full throttle; that makes it more effective. And, of course, more classic-Who.

So, how many Amy deaths and Doctor deaths do we have now? They're not just picking on Rory. Some days, nobody dies. Some seasons, everybody dies, again and again.

I'm sure we'll understand later why the Doctor had to kill ganger-Amy, but what puzzles me most about it is why Rory accepted it.

Reverse the jelly baby of the neutron flow, I'm, would you like a Doctor? "One day we will get back, yes, one day. Reverse the polarity of the neutron flow. Would you like a jelly baby? Why? Why? Why? Hello, I'm the Doctor. No, let it go, we've moved on!" OK, so that's 1, 3, 4, 5, 7, and... ? And where was Matt Smith's favorite Doctor, 2? Couldn't he at least have wrung his hands and said "Oh my" or something?

I really liked this episode, so much more than I did The Rebel Flesh. Yes, there was a LOT of padding, but the episode didn't slow down because of it, something the previous episode did do. It was perfectly creepy and had a good mix of talky-talky scenes and action.

Was The Doctor mumbling something about cybermats at one point?

Yes, he was. He asked the Ganger Doctor about the Cybermats to see if he really was the Doctor. He wanted to know if the Ganger Doctor actually had his knowledge, to be sure that they were one and the same.

After Rory saw his friend (I forgot her name already) be killed as he thought she was the ganger but it was actually the other one, that's why he trusted the Doctor when he told him to step aside from Amy; Rory had been fooled once already and besides Rory trusts the Doctor.

Poor Amy, I thought I'd never say that. To find she's been kidnapped probably the entire series and pregnant and alone in that crazy woman's clutches, that's the only part of the episode that actually scared me as I’m frighten for Amy.

I can't wait to see what happens next.

Yet I have a concern that the series is starting to look like one of those old Mission Impossible episodes. The series has been easy to follow so far but I hope the rest of it doesn't get more convoluted than this.

How come the Doctor spends so much emotional effort on telling people that Gangers have as much right to live as anyone, then blows up Amy without even giving her the chance to help find her actual body?

@MrGrumpy:
He had to kill off the ganger Amy so that the real one could give birth. It's one Amy in two bodies, she was controlling the one that wasn't pregnant, which is seemingly very dangerous when the real one is in labour. Hope that makes sense.

Yep I'm with you on that one Sean.

This ep was much better than the last, and better than everything else this series save for the Moffat eps.

I wonder how they'll explain the way Amy could "control" her ganger across multiple times and dimensions. It breaks my suspension of disbelief when a show breaks its own internal rules.
