In the latest commentary, Russell T Davies, Julie Gardner and David Tennant talk of some stuff which MAY be of very interesting interest; so interestingly mad that I can't even type at the moment! :D
Russell: ...because long ago the Ood said, "I think your song is sending soon,"
Russell: They knew, but how do they know? How can Ood be that psychic and that intelligent? How? What's happening? What's going on in the universe?
Julie: You big, big tease.
David: Time is running away with itself somehow.
Russell: You'd think something is bleeding, coming through from the other side. Very strange...
David: We'll have to come back and see what happens there...
What could this mean?! Many have suggested the parallel universe ("the other side")??
You can listen to the commentary HERE.
And also a warning, that the Children in Need sneak peek will not be online! What is this outcry I hear? More viewers for Children in Need (and quite right too! :D).
