"You look Time Lord."

I remember somewhere Moffat saying that he felt the second half of a two-parter should never open exactly where Part One left off. His reasoning is that since it'd been a week since the viewer had last seen our heroes, there should at least be a change of scene -- also that he didn't care for the opening of "The Doctor Dances" for just that reason.

::shrug:: It's clearly one of his personal writing rules.
