So that's where the Tenth's control room appears. We'd seen pictures of Amy and Rory in the old control room and here it appears as an archived room in the TARDIS. A back-up, as it were.
This week's episode was all about the Doctor's relationship with the TARDIS as 'she' finally found her voice. And what a fantastic episode it was. Just brilliant.
When the only complaint I can make was that the only bit of the TARDIS we saw (other than that old control room) was lots of the same corridor then it can't be bad. Well, sometimes it went a bit too fast to keep up as well I suppose...
Still all I can say is marvellous!
Then there was that little prediction at the end: "the only water in the forest is the river". What with a river, a forest and the silence this all sort of points towards the Silence In The Library/Forest Of the Dead episodes from a couple of series ago. Are they still in the library then? Perhaps saved in the computer like River?
And, of course, a pond is made of water. So does this mean River is Amy Pond? Or that Amy doesn't really exist, only River?
Yet another mystery to add to the rather large list.
Next week there's another two parter and it looks pretty spooky!
