... On rewatching, right at the beginning, with the closing Tardis doors and then Amy opening her suitcase; was that deliberately meant to evoke opening Pandora's box?

And the structure is even more striking on rewatching. Loved that the "young lovers' curse" line applies to both Amy/Rory and River/the Doctor. (Seriously, that bit just made me wibble, because River/the Doctor is such a tragic relationship...)

Also, d'you mind if I rec this? It's utterly fantastic.
