I loved this episode, but one. basic. question: WHY THE HELL DID HE GO BACK THROUGH THE FIREPLACE?!
Seriously, if he knew he was gonna bring her with him, why didn't he just open it up again? Why? I mean, apart from the whole "negate the entire purpose of the episode" thing. Just... this is me being frustrated. I knew what was coming even more than common sense said, and so... frustrated.
I also clearly love everything Steven Moffat writes from Press Gang onwards -- and I loved the throw-backs, with both bananas and dancing (the Doctor couldn't afford to carry a banana here in Oz -- they're worth their weight in gold right now).
Hee. Just on Wikipedia and someone compares this episode to The Time Traveler's Wife; clearly, I was meant to love this episode.
