This is so great and compelling so far!!! Of course it just makes me want moooooooore. :) Especially a scene where they realize they're all actually time travelers, oh man! I'm just completely in love with the idea of them as this little family unit. <3

(Not sure if this is relevant to your story, but in my head River has always known that Amy was their daughter - since Amy's birth would be in her past - but kept it hush-hush because it was still in the Doctor's future... which makes canon complicated but it's AU so who cares! lol. Just a thought. :)
