Just noticed that for the majority of the episode Amy's hair was wavy, but for some of the scenes within the bowels of the Tardis it was poker straight. It jared when I seen it.

I have no idea if it could mean anything but just something that stuck out to me

re watched a bit and her hair is a different style in the scene when she is in the dark an Rory see's her in the light. maybe it was a pick-up
