I was thinking last night that perhaps Amy is being set up for a fall - because all this stuff about her knowing the Doctor so well is actually starting to tell ME that in fact, she doesn't know him AT ALL. When she saved the day in TBB there was a lot going around about how she'd been dreaming of him for years, so she knew him (which is bollocks), so of course she could see things he couldn't etc. But now I'm wondering if we're meant to see that her ideas about him are just a fantasy.
