And your problem is? It's credible for a normal person with wedding nerves who wants a last fling even without the added complication of this guy being the guy she's been obsessed with since childhood who's suddenly reapeared just as she was about to settle for 'nice but dull' (asRory then seemed...)
And then she got over it... like she would in real life the next morning with a hangover and regrets...
Exceptionally well put. Amy was realer in that moment than Rose or Martha ever were.
To add, she'd also just nearly died which likely exacerbated her feelings even more.
Indeed. As soon as the scene began where Amy and the Doctor were in her bedroom at the end, I immediately predicted (correctly) what was going to happen. I'm normally a very prudish person who doesn't go for such raw displays of, um, "affection", on television, but in this particular case, it was totally appropriate in the context of the story and a very realistic way for Amy to behave in that situation.
