I am basically not thinking too hard about such things. There are mind things going on and timeline things and altern-universe things and then there is Moffat doing WTF?Moffat! things and . . . and there was this time when the Pandorica opened and Amy was inside and *then* it got complicated but somehow it all made sense in the end, so . . . . Probably it will be ok. Symbolism says she's their daughter.

(Did the Silence steal the child and mindwipe them both? Because they would tear the universe to pieces...)
Remember that episode that was made up entirely of BORING and HEAVY-HANDED? And there was that pirate-y guy who the story kept trying to be like *nudge, nudge* 'isn't he kinda like the Doctor?" *nudge* but then there was unexpected!kid, and he was like WTF? kinda do not want? go away! And then kid was sick and got disappeared and he had to hurt himself and get taken away by the thing that came out of the water so he could go get him back and they could be space pirates together?

Yeah, that happened. I don't know why I brought it up. Just felt like complaining.
