Ohhhhh that makes a whole lot more sense. Thank you! I also wondered why there wasn't a bit more continuity/reference to the previous two-parter.

Hmmm...which makes the Doctor's "all together, in the flesh" comment (I'm paraphrasing) even more interesting, if it was intended to be pre-RF/AP, like he was hinting at what was to come. I kind of wondered why he would say that after, since I'd think it would be a sore spot for Amy.
