I could see this as a perfectly feasible and whoppingly fantastic DW episode. I loved the way you described the TARDIS, very much from a curious human's perspective. You also remind me of the reasons why I like Amy (and it took me till The Pandorica Opens to warm to her), insofar as you show her imagination, her vulnerability and her innocence. Very lovely. (Just an ickle more married-couple-awesomeness from Doc and Riv next time pwetty pweeeasse?)
