Okay, just watched it again.
So, unless I'm hearing it wrong, the Doctor definitely knows a lot more than he's saying with regards to the situation in this episode, even more than usual. The Doctor talks about a crossroads, about making the right decision, and about the Flesh being just the early stages of the technology. So presumably this is another point in history that's in flux and can have a massive impact on the future, and he knows how it originally turned out and decides to undo it.
They're mining acid and shipping it to the mainland. Why? Is this just a MacGuffin and convenient obstacle, or is it going to end up being very important to the plot?
I'm liking Amy less and less.
I wonder if mention of Rory remembering his time as living plastic will come up in the next part, since it could well be relevant to the Ganger's situation.
Did the Doctor deliberately create his duplicate, perhaps to reach out to the Gangers and the humans, show them they can co-operate? It only appears after he ducks into the chapel with the Flesh and uses his sonic on it for quite some time, then simply leaves. Or is it a byproduct of him trying to do something else with the Flesh?
So, Cleaves' crew aren't military, but contractors for the military - so what is the military's interest in the Flesh, or the acid? An ability to field armies where combat losses aren't nearly as bad because the original operator remains, or something even more sinister? The hardwiring of the minds and personalities of the operators by the electrical discharge (especially with Buzzer's mention of the Isle of Sheppey incident) - is that entirely accidental?
Liking the episode a bit more now, but it still feels a little too drawn out.
