Hmmmm. So does that mean she was normal!pregnant (by Rory, one assumes), then got kidnapped in the orphanage and her captors did something to make it a Tiembabby? That kind of... blows a hole in my hunch that Amy was being used as a surrogate for a Tiembabby created out of the Doctor's DNA.

And this is all assuming the Tiembabby in the spacesuit is in fact Amy's kid.

*shakes fist* MOFFAT!!!
