Ok the episode blew me away, seriously.

First up good call to Penelo Ratsbane, you called River Song as Amy's daughter, something I myself had begun to consider around the 3rd episode. Especially once the riddle of "the only water in the forest is the river" riddle came up. As soon as River said she couldn't go and then you see the name "Melody Pond" on the side of the incubation crib you know, you just know that it's River.

This also put a damn good spin on the whole first two episodes. We know it was River Song/Melody Pond in the space suit now. We also know that adult River shoots at it with her magnum, 6 shots which seemingly miss, except River Song is the one person in the universe where missing I doubt is actually possible. Perhaps she didn't miss but it was deemed impossible for her to kill herself? I don't know. It also makes me think of every River episode ever, she told Rory that she went to prison for killing the best man the Doctor had ever known, I've long suspected she killed the Doctor himself. Now it's confirmed......

my head just entered thermo nuclear meltdown after a good few beers, 2 movies and a Doctor Who episode watched at 2:30 am. I'm just going to say "lets kill Hitler" now and end before my mind goes critical.
