My thoughts: If the flesh replicates blood clots should it not also replicate a foetus? I think Amy was replicated before she was pregnant. When Amy tells the Doctor she's pregnant and then says she's mistaken, that's the ganger being run by captured Amy - trying to send a message or just confused?

I dearly love the way Matt Smith works his mojo, talking to captured Amy through ganger Amy: we will find you. And, of course, I just want to pet and hug Rory's reactions.
