Much ink has already been spent on last Saturday's Nu Who episode, '
The Girl Who Waited'. Not wishing to add much which has already been said, here instead is another reading of the episode:
Rory has an
Oedipal relationship with the Doctor who he sees as the father figure getting in the way of his 'mother', Amy. (How else to explain his obsessive love with her?) This reaches crisis point when he meets the older Amy who really is now old enough to be his mother. The Doctor forces Rory to choose between the young Amy (who's the right age for Rory and so represents a social norm that the Doctor, as father figure, is trying to enforce) and the old Amy, who is a physical manifestation of Rory's libido.
This explains Rory's anger - 'you're trying to turn me into you!', he says, and what is meant is that the Doctor is, by hook or by crook, trying to make Rory an adult who identifies with his 'parent' and so social norms. That he is forced perform the Doctor's adult responsibilities - to fill his shoes and see things through the Doctor's glasses - is revealing too.
