Amy finally gets to ask the Doctor the question that has been plaguing her since DW: Space: how can she remember two distinct histories of her life since the universe was rebooted in DW: The Big Bang? The Doctor in part answers her question by giving her a chance to do a good deed for herself when she was a child.
